Description

Пробирку 8 наполн ют на 1/2 своего объема водой и замер ют термометром ее температуру.The tube 8 is filled to 1/2 of its volume with water and its temperature is measured with a thermometer.

Затем пробирку с испытуемым образцов 9 через отверстие в крышке 6 кожуха 5Then the test tube with the test sample 9 through the hole in the lid 6 of the casing 5

ввод т в нагреватель 7.injected into the heater 7.

Поворотом кронштейна 3 устанавливают шток индикатора 4 на торец образца 9, стрелку индит.атора став т в нулевое положение .By turning the bracket 3, the indicator rod 4 is installed on the end face of sample 9, the individual pointer of the indicator is set to the zero position.

Включают прибор и нагревают содержимое в пробирке 8 до кипени .Turn on the device and heat the contents in the tube 8 to a boil.

При кипении водь, в пробирке испытуемы образец нагреваетс  до 1ОО°С. Увеличение длины образца определ ют по отклонению стрелки индикатора от нулевого значени .When boiling water, in the test tube, the sample is heated to 1OO ° C. The increase in sample length is determined by the deviation of the indicator arrow from zero.

Рассчет коэффициента линейного расширени  производ т аналитически.The linear expansion coefficient is calculated analytically.
