T '=2 π (1/9)
1/2, 1 is pendulum length in the formula, and unit is a rice, and g is an acceleration of gravity, and unit is a meter per second
2Half period T=T '/2=π (1/9)
1/2Pulsewidth t is relevant with the amplitude of oscillation, and the amplitude of oscillation is big more, and the pendulum of single pendulum 1 is short more through the time of sensitive zones, and t is short more; Otherwise the amplitude of oscillation is more little, and t is long more.The unit of t is second.The scope of t can be represented with inequality:
0＜t≤T。
When the input B of alarm 3 obtained constant positive voltage, IC 31 the 4th foot obtained positive bias (as 9 volts), makes IC 31 enter duty, because the bias voltage of the 2nd foot is 0, be lower than 1/3 supply voltage (as 3 volts), therefore, the 3rd foot output high pressure (as 9 volts).IC 32 is worked because of the 4th foot obtains positive bias.During beginning, capacitor C 31 is uncharged, and its voltage is that the bias voltage of 0, the 6 foot is identical with the 4th foot, is 9 volts also, is higher than 2/3 supply voltage (as 6 volts), therefore, and the 3rd foot output low pressure, (as 0 volt).IC 33 obtains powering through the 3rd foot of the 4th, 8 feet from IC 32, and at this moment, the former does not work because of can not get power supply, and IC 33 is audio oscillatores of band speaker, the blocking of oscillator, and speaker Y31 is sounding not; Process T1 time delay is after second, along with capacitor C 31 is charged through resistance R 32, the bias voltage of the 2nd foot of IC 32 reduces, this bias voltage is lower than 1/3 supply voltage (as 3 volts), the 3rd foot converts the output high pressure to, IC 33 thereby obtain the power supply and vibrate, the audio signal of output is through the 3rd foot, capacitor C 35 is added in the two ends of speaker Y31, and speaker Y31 shouts a shout.Can estimate with following formula time delay:

1, t＜T: in during t, the input signal of alarm 3 is a positive pulse, and the bias voltage of the 2nd foot of IC 32 descends, but permanent in 1/3 supply voltage (as 3 volts), the 3rd foot output low pressure, and IC 33 is not worked, and speaker Y31 is sounding not.After 1 end, alarm 3 input signals become 0, the 3rd foot output low pressure of IC 31, filled electric capacitor C 31 through discharging to the 3rd foot of IC 31 along the diode D31 that connects, extremely low along the impedance of the diode D31 that connects, discharge process lasts of short duration, the terminal voltage of capacitor C 31 almost side promptly reduces to 0, the 3rd foot output low pressure of IC 32, IC 33 is not worked, and speaker Y31 is sounding not.State when so far circuit is back to this section beginning again.The amplitude of oscillation of expression single pendulum 1 is big, judges tested focusing on.
2, t=T: alarm 3 input signals are constant positive voltage, and alarm 3 postpones to send the cry that frequency is f behind the T1.The amplitude of oscillation of expression single pendulum 1 is minimum, and pendulum swings near sensitive zones all the time or single pendulum 1 stops, and judges that tested attention is concentrated.
Two, T1＜T.
1, t≤T1: same, 1, situation, just do not repeat here.
2, T1＜t＜T: t-T1 during this period of time in, alarm 3 sends the of short duration cry that frequency is f, t approaches T1 more, cry is lasted of short durationly more, t approaches T more, cry is lasted long more.The pendulum of single pendulum is every through sensitive zones once, and alarm 3 just sends once cry.The amplitude of oscillation of expression single pendulum 1 obviously reduces, and judges that tested attention tends to concentrate.
3, t=T: same, 2, situation, just do not repeat here.
