Description

A method for detecting moxa mass by combining terahertz wave and combustion temperature

technical field

The invention belongs to the technical field of medical detection, and in particular relates to a method for detecting the quality of moxa pillars by combining terahertz waves and combustion temperature.

Background technique

Moxibustion is highly regarded for its effects on warming meridians, reconciling qi and blood, coordinating yin and yang, strengthening the body and eliminating pathogens. The curative effect of moxibustion is a comprehensive result of many aspects. It generates heat energy by burning moxa, causing changes in the body temperature, which not only affects the surface layer, but also penetrates deep into the body through acupoints and meridians, so as to achieve the purpose of curing diseases and maintaining health. Warm stimulation is a moxibustion method. a very important part of it. In the clinical treatment process, moxibustion mainly stimulates acupoints through acupoints, drugs, heat radiation and infrared radiation, so as to achieve a therapeutic method for preventing or treating diseases.

There are many kinds of moxa on the market. There are differences in the origin, raw materials and production methods of moxa. Various brands of moxa are of uneven quality and mixed with fish. The quality of moxa is different, and its combustion conditions are also different. Therefore, it is an effective measure to analyze the thermal effect of moxibustion and study the quality of moxa pillars by detecting the combustion temperature of different moxa pillars and discussing different temperature changes.

Terahertz wave technology is a technology with rapid development, broad prospects and a wide range of fields. The terahertz wave band is between microwave and infrared waves, with strong penetrability, good directionality, low energy release, and complete non-ionization Features. When the moxa is burning, it can continuously transmit energy in the form of electromagnetic waves. Its combustion spectrum is distributed from the near-infrared to the far-infrared band. The far-infrared wave and the terahertz wave have the same wavelength. After long-term research, the R&D team of column quality detection applied for and authorized an invention patent in January 2020. The name of the invention patent is "A method for detecting the quality of moxa column using terahertz waves", and the patent number is 202010000161.6. The energy level of the terahertz wave generated during the combustion process of the moxa column is measured by a terahertz spectrometer, and the quality of the moxa column is judged by combining the waveform changes. Although the quality detection method of the moxa column is novel, the judgment is still based on a single test, which cannot fully explain the quality of the moxa column. In particular, the terahertz waves generated by the combustion of different brands of moxa column may cross the trend of intensity values in different bands. , resulting in the above single detection because the relative strength of the terahertz wave cannot be distinguished, so the relative quality of the moxa column cannot be accurately judged.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is: for the existence of the invention patent (patent number 202010000161.6, patent name "a method for detecting the quality of moxa column using terahertz wave") published by my research and development team in January 2020 It provides a more perfect moxa column quality inspection method. Since the "method for detecting moxa mass by using terahertz waves" may cross the trend of intensity values of terahertz waves in different wavelength bands generated by the combustion of moxa of different brands, the above single detection cannot distinguish the relative intensity of terahertz waves. Weakness, so that the relative quality of moxa column cannot be accurately judged. Based on this patented technology, my research and development team has further conducted in-depth research on the quality detection method of moxa column. Combined, it can more accurately detect and comprehensively judge the latest research results of the quality of Aizhu, as the main content of this follow-up invention application.

The invention provides a method for detecting the quality of moxa column by combining terahertz wave and combustion temperature. The method uses the nuclear magnetic spectrometer to measure the nuclear magnetic wave energy generated in the combustion process of the moxa column, and uses the thermocouple to detect the maximum combustion temperature, in order to establish a comprehensive judgment of the mass of the moxa column by measuring the terahertz magnetic wave energy and the combustion temperature of the moxa column combustion. method. Since heat and electromagnetic wave effects are the important biophysical basis for moxibustion treatment, a more reliable detection method is provided to detect the quality of moxa column by combining terahertz wave and combustion temperature. The detection and judgment method can better solve the problem that the quality of the moxa column cannot be accurately judged by the single detection of the terahertz wave due to the intersection of the terahertz waves of the moxa column. The present invention provides a more accurate and reliable detection method for the quality control standard of the moxa column manufacturer, and facilitates the accurate judgment of the moxa column user on the quality of the moxa column. The invention has the advantages of simple and sensitive method, accurate and reliable data, short detection time, low detection cost and the like. This patent application combines the terahertz wave with the combustion temperature of the moxa pillar to detect and judge the quality of the moxa pillar, and no relevant reports have been seen yet.

The present invention adopts the following technical solutions to achieve the purpose of the invention.

A method for detecting the quality of moxa pillars by combining terahertz waves and combustion temperature. Before testing, first sample multiple copies of the same moxa pillar to be tested, and prepare items and instruments. The main items are: moxa pillars, fixtures, lighters, candles, Calipers, timers, etc.; the main instruments are: terahertz spectrometer, temperature tester, thermocouple, electronic balance, etc. The detection method includes the following steps:

S1. Take a portion of the moxa column to be tested to measure the burning time and temperature of the moxa column;

S2. Take another copy of the same moxa column and place it in the terahertz spectrometer;

S3, determine the background value of the unburned moxa column;

S5. Data processing: including data processing of moxa-column combustion temperature and data processing of moxa-column combustion terahertz wave intensity value;

S6. Comprehensively judge the quality of the moxa column according to the data processing result.

The quality of moxa pillars of various brands is uneven, and their combustion conditions are also different. Therefore, by detecting the combustion temperature of different moxa pillars and discussing different temperature changes, we can analyze the thermal effect of moxibustion and study the quality of moxa pillars; terahertz (terahertz (terahertz) THZ) wave is an electromagnetic wave with a frequency of 0.1-10THz, which is in the transition band from macro-electronics to micro-photonics. When the moxa column reaches a certain temperature during the combustion process, it will generate thermal radiation, and the terahertz wave is also in the wavelength range of radiation. quality. The effect of heat and electromagnetic waves is an important biophysical basis for moxibustion treatment. The invention combines the combustion temperature and the terahertz detection method to analyze moxa columns of different brands or series, and provides a more reliable comprehensive judgment of the quality of the moxa columns. The detection method is more accurate and comprehensive for the quality evaluation and judgment of moxa.

Further, determining the burning time and temperature of the moxa column described in step S1 is specifically: igniting the moxa column, using a temperature tester to measure the burning temperature of the moxa column, and recording the burning time.

Preferably, the temperature tester is a thermocouple temperature tester; the thermocouple temperature tester is an MT-X multi-channel temperature tester equipped with a K-type armored thermocouple.

Further, the placing in the terahertz spectrometer described in step S2 is specifically: fixing the moxa column on the shelf so that it is located at the center of the terahertz spectrometer launch port, 16 cm away from it.

Preferably, the terahertz spectrometer is Bruker vertex 80v.

Further, the background value described in step S3 is the terahertz band background radiation electromagnetic wave of the earth; the described background value of measuring the unburned moxa column is specifically: calibrating the equipment, detecting the moxa column terahertz wave multiple times in the unburned state , take the average value.

Further, the determination of the terahertz wave energy of different wavebands in the combustion of the moxa column described in step S4 is specifically: 10 seconds after the moxa column is ignited, start the detection with a terahertz spectrometer, and detect the terahertz wave intensity in the 1-50 band of the burning moxa column and repeat the measurement several times.

Further, the data processing described in step S5 includes: data processing of the combustion temperature of the moxa column, and data processing of the terahertz wave intensity value of the moxa column combustion.

Preferably, for the data processing of the combustion temperature of the moxa column, SPSS21.0 software is used for data processing and analysis to obtain the highest combustion temperature.

Preferably, the data processing of the terahertz wave intensity value of moxa column combustion is processed by spss statistics21 statistical software, and the 1-50 band intensity value of each brand is compared with the 1-50 band intensity value of the blank control group, and the comparison is different. One-way ANOVA was used to analyze the terahertz wave energy of different bands produced by the combustion of brand moxa.

Further, the comprehensive judgment of the quality of moxa pillar described in step S6 is: according to the terahertz wave intensity change of moxa pillar combustion, combined with the highest combustion temperature of moxa pillar combustion, the quality of moxa pillar is judged in two dimensions comprehensively, if moxa pillar 1 The stronger the terahertz wave intensity in the -50 band and the higher the maximum combustion temperature of the moxa column, the better the quality of the moxa column; if the trend of the terahertz wave intensity and the highest combustion temperature are inconsistent, the terahertz wave intensity of an moxa column is stronger but The highest combustion temperature is lower, and the terahertz wave intensity of the other Ai column is weaker but the highest combustion temperature is higher. At this time, the quality of the Ai column is judged by taking the terahertz wave intensity in the 1-50 band of the Ai column as the first dimension. The one with the stronger terahertz wave in the 1-50 band can be judged to be of better quality; if the terahertz wave waveforms of the two moxa columns in the 1-50 band are crossed, it is difficult to distinguish the relative strength of the terahertz wave. The highest combustion temperature is used to judge the quality, and the one with the higher maximum combustion temperature of Aizhu can be judged to be of better quality.

Combining the test results of moxa terahertz wave with the highest combustion temperature, it can provide a more accurate and reliable detection method for moxa manufacturer's quality control standards, which is convenient for moxa users to accurately judge the quality of moxa.

It has the advantages of simple and sensitive, accurate and reliable data, short detection time and low detection cost.

According to the terahertz wave detection data of the 1-50 band of the moxa mass and the highest temperature when the moxa is burned, the moxa user can intuitively and accurately judge the moxa mass. If the intensity of the terahertz wave in the 1-50 band of the moxa is stronger and the maximum combustion temperature of the moxa is higher, the quality of the moxa is better; if the terahertz wave intensity and the highest combustion temperature are inconsistent, the terahertz wave of a moxa is inconsistent. The intensity is stronger but the maximum combustion temperature is lower, and the terahertz wave intensity of the other moxa column is weaker but the highest combustion temperature is higher. At this time, the terahertz wave intensity in the 1-50 band of moxa is the first dimension to judge the quality. , that is, the one with the stronger terahertz wave in the 1-50 band of the moxa column can be judged to have better quality; if the two terahertz wave waveforms in the 1-50 band of the moxa column intersect, and it is difficult to distinguish the relative strength of the terahertz wave, then The quality is judged by the highest combustion temperature of the moxa, and the one with the higher highest combustion temperature of the moxa can be judged as having better quality.

Each moxa column was observed for 6 strong. After the moxa column was burned, the temperature measurement program was closed when the temperature dropped to room temperature, and SPSS21.0 software was used for data processing and analysis.

Table 2: Maximum combustion temperature of 15 series of moxa columns based on five brands

(2) Data processing of the terahertz wave intensity value of moxa column combustion:

The spss statistics21 statistical software was used for processing, and the one-way analysis of variance was used to compare the terahertz wave energy in different bands produced by the combustion of different brands of moxa. Specific processing data: each moxa column measures the terahertz magnetic wave intensity value in the 1-50 band, and the intensity value of each band is repeatedly measured several times, and the average value is taken. The 1-50 band intensity values of each brand were compared with the corresponding band intensity values of the blank control group. Figure 2, Figure 4, Figure 6, Figure 8, Figure 10, Figure 13 for the terahertz wave intensity values in the 1-50 band of Aizhu of different brands. in:

Figure 2 shows the intensity of terahertz waves in the 1-50 band of five different moxa columns of Poaitang brand;

Figure 8 is a graph of the terahertz wave intensity in the 1-50 band of two different moxa columns of Qidama brand;

Fig. 10 is the terahertz wave intensity map of 1-50 band of two different moxa columns of Yaoyibao brand;

Figure 13 is a graph of the terahertz wave intensity in the 1-50 band of five different moxa columns with the highest combustion temperature of each brand. Among them, the five different Aizhu are: 5 times Aizhu (Song) in Poaitang brand, 5:1 Aizhu in Aiqinkang brand, Jiang Aizhu in Lvyuantang brand, Aunt Qi in Qidama brand. In September, Aizhu, a gynecological Aizhu in the Yaoyibao brand, was produced.

4. Judgment on the quality of Aizhu in different series of the same brand:

According to the change of terahertz wave intensity, combined with the highest combustion temperature of moxa column, the quality of moxa column is comprehensively judged. it is good.

It can be seen from Figure 3 that the highest combustion temperature of Aizhu in the Song Dynasty (5 times) in Poai Hall is the highest, and the descending order is Yuan (4 times), Tang (6 times), Ming (3 times), Qing (2 times) Aizhu Column (see Figure 3), corresponding to the trend of terahertz wave intensity in Figure 2, the comparison between groups was not statistically significant (P>0.05).

It can be seen from Figure 5 that the highest combustion temperature of the moxa column with the cashmere ratio of 5:1 in Aiqinkang is the highest. The terahertz wave intensity trend in the two groups was the same, and there was a very significant difference between the groups, with statistical significance (P<0.01).

It can be seen from Figure 7 that the highest combustion temperature of Jiang Aizhu in Luyuantang is the highest, followed by ten-year golden moxa and five-year warm moxibustion moxa. The trend changed alternately, the five-year warm moxibustion moxa column was the lowest, the two were basically the same, and there was a very significant difference between the groups (P<0.01).

It can be seen from Fig. 9 that the highest combustion temperature of Aunt Qi produced in September is higher than that of Aunt Qi produced in July, which is consistent with the terahertz wave intensity trend of Aunt Qi produced in September in Fig. 8. Aizhu produced in September was also stronger than Aunt Qi, and there was a very significant difference between the groups (P<0.01).

It can be seen from Figure 11 that among the Yaoyibao brand moxa, the highest combustion temperature of gynecological moxa is higher than that of ordinary moxa, which is also consistent with the trend of terahertz wave intensity of gynecological moxa in Figure 10, that is, gynecological moxa is higher than ordinary moxa. Ai Zhuqiang, there was little difference between the groups, and there was no statistical significance (P>0.05).

From the comparison of the maximum combustion temperature and terahertz wave intensity of different series of moxa columns of the five brands selected above, it can be seen that the highest combustion temperature and terahertz wave intensity of different series of moxa columns of the same brand have good consistency.

The curative effect of moxibustion is inseparable from the warm stimulation produced by the burning of moxa pillars. Under the premise of human body tolerance, care should be taken to avoid adverse reactions such as pain, blistering, and suppuration. If moxa pillars can reach a higher burning temperature, the Its penetrating ability is stronger, it can better exert its curative effect, and the quality of such moxa column is better. If the terahertz wave intensity in the 1-50 band of the moxa is stronger and the maximum combustion temperature of the moxa is higher, the quality of the moxa is better.

Figure 12 lists the results of the analysis of variance for the highest combustion temperature of 15 series of moxa columns for five brands. Among them: Poaitang brand Aizhu 1-5 are respectively 6 times Aizhu, 5 times Aizhu, 4 times Aizhu, 3 times Aizhu, 2 times Aizhu; Aiqinkang brand Aizhu 1-3 are respectively The cashmere ratio is 5:1 moxa, 15:1 moxa, 25:1 moxa; Luyuantang brand moxa 1-3 are five-year warm moxibustion moxa, ten-year gold moxa, Jiang moxa; Qi Aunt brand moxa 1- 2 are the mugwort column produced in July and September respectively; the medicine Yibao brand mugwort column 1-2 are the ordinary mugwort column and the gynecological mugwort column respectively.

From the variance analysis results of the maximum combustion temperatures of various moxa columns in Figure 12, it can be known that:

The maximum combustion temperature of Jiang Aizhu in the Luyuantang brand, the gynecological Aizhu in the Yaoyibao brand, and the Aizhu produced in September in the Qi Aunta brand obviously exceeds 600 °C. If you only consider the maximum combustion temperature from a single dimension, It seems that these three kinds of moxa are of the best quality; while the five kinds of moxa in the Poaitang brand, the ten-year gold moxa in the Luyuantang brand, and the common moxa in the Yaoyibao brand, the highest combustion temperature is 600 ℃ Up and down, if only from the single dimension of the highest combustion temperature, it seems that the quality of these seven kinds of Aizhu is also better; while the three series of Aiqinkang Aizhu, the five-year Jin Aizhu in the Lvyuantang brand, and the Qi Aunta brand The maximum combustion temperature of the mugwort column produced in July is significantly lower than 600 ℃. If only considering the single dimension of the highest combustion temperature, it seems that the quality of these five kinds of mugwort column is poor. However, in order to judge the relative quality of the moxa column, it is necessary to combine the two dimensions of the terahertz wave intensity and the maximum combustion temperature of the moxa column to formulate a unified judgment standard and make a comprehensive judgment.

5. Comprehensive judgment of the quality of Aizhu:

The invention comprehensively judges the quality of different moxa columns by detecting the terahertz wave intensities of different moxa columns in the 1-50 band and combining with measuring the highest combustion temperature of different moxa columns. The comprehensive judgment criteria are suggested as follows: (1) if the terahertz wave intensity in the 1-50 band of moxa is stronger and the maximum combustion temperature of moxa is higher, the quality of moxa is better; (2) if the intensity of terahertz waves is related to the highest combustion temperature The two trends are inconsistent. The terahertz wave intensity of one moxa column is stronger but the maximum combustion temperature is lower, and the terahertz wave intensity of the other moxa column is weaker but the maximum combustion temperature is higher. It is good to judge the quality of the Hertz wave, that is, the one with the stronger terahertz wave in the 1-50 band of the moxa column can judge the quality to be better; (3) If the two terahertz waves in the 1-50 band of the moxa column have crossed, If it is difficult to distinguish the relative strength of the terahertz wave waveform, the highest combustion temperature of the moxa column is used to judge the quality.

Figure 13 is a graph of the terahertz wave intensity in the 1-50 band of five different moxa columns with the highest combustion temperature of each brand. Combining the terahertz wave intensity maps of five different moxa columns with the highest combustion temperatures in the 1-50 band in Fig. 13 and combining the highest combustion temperatures of moxa columns in Table 2, we can see that:

Among the five kinds of moxa, the 5 times moxa in the Poaitang brand has the best quality. Although the maximum combustion temperature of the moxa column (609.30°C) is not the highest, according to the above judgment criterion (2): if the trend of the terahertz wave intensity and the maximum combustion temperature are inconsistent, the terahertz wave intensity in the 1-50 band of the moxa column is used at this time. Weak to judge the quality, because the terahertz wave intensity in the 1-50 band is relatively strongest among the five different moxa, so it can be judged that the quality of the 5 times moxa in the Poaitang brand is relatively best;

Secondly, the quality of Aizhu produced in September in the Qi Aunt brand is relatively good. The terahertz wave intensity of the moxa column in the 1-50 band is second only to the 5-time moxa column in the Poaitang brand, and the maximum combustion temperature of the moxa column is 617.52 ℃, so the quality of the moxa column is relatively good;

The quality of Jiang Aizhu in the Lvyuantang brand is relatively poor. Although the highest combustion temperature of the moxa column is the highest among the five moxa columns (628.85°C), because the terahertz wave intensity of the moxa column in the 1-50 band is relatively weak among the five different moxa columns, the mass of the moxa column is relatively the lowest. Difference;

It can be seen from Figure 13 that the cashmere ratio of Yaoyibao brand gynecological moxa and Aiqinkang brand is 5:1 moxa, and the terahertz wave shape of the two in the 1-50 band is stronger than that of the Luyuantang brand. The Jiang Aizhu is weaker than the Poaitang brand 5 times Aizhu and Qi Ama brand Aizhu produced in September, and the waveforms of the two intersect, so it is difficult to distinguish the relative strength of the terahertz wave. According to the above judgment criterion (3): if the terahertz waveforms of the 1-50 bands of the two moxa columns intersect, and it is difficult to distinguish the relative strength of the terahertz wave waveforms, the highest combustion temperature of the moxa columns is used to judge the quality. Since the maximum combustion temperature (623.63°C) of Yaoyibao brand gynecological moxa column is higher than the highest combustion temperature (562.82°C) of Yaoyibao brand gynecological moxa, which has a cashmere rate of 5:1 in Aiqinkang brand, it can be determined that Yaoyibao brand gynecological moxa The quality of the column is slightly better than that of the 5:1 Ai column in the Aiqinkang brand.
