摘要
介绍用绝对零度球体与压力传感器和温度传感器配合,在定容条件下测量气体的压强与温度,采用外推法估算理想气体可以达到的最低温度(绝对零度)的摄氏温度值,替代原先用玻璃管测体积和水银温度计测温度。使用新的绝对零度实验装置,可以更明显地观察分析热力学现象,并使测得的绝对零度值较为精确。
The introduction coordinates with the absolute zero degree spheroid and the pressure transmitter and the temperature sensor, Surveys pressure and temperature of the gas under the volume condition. Uses extends the law estimate fire gas may achieve most low temperature（absolute zero degree） centigrade temperature value. The substitution originally uses the glass tube to measure the volume and the mercury thermometer measures the temperature. Uses the new absolute zero degree experiment installation, may obviously observe the analysis thermodynamics phenomenon, and causes the absolute zero degree value which obtains to be precise.
