碳电阻温度计经验公式的选用比较

The Comparison Of Selection For The Experimental Formula Of Carbon Thermometer

碳电阻温度计是低温温度测量的常用温度计之一。在碳电阻温度计标定过程中 ,经验公式的选用对碳电阻温度计标定曲线的正确性有着重大的影响。文中针对这一问题 ,同时结合对现有几十个碳电阻温度计的标定实验 ,得到了碳电阻温度计经验公式的选用受碳电阻温度计本身的材料和其所处的温区等因素制约的结论。

The carbon thermometer is one of the commonly used thermometers that measure temperature in cryogenic engineering. In the course of calibration of carbon thermometer,the selection of the experimental formula of carbon thermometer will affect the validity of the calibrating curve greatly. In order to answer this question, we take dozens of experiments of calibration of the carbon thermometers. The test results show the selection of the experimental formulae of carbon thermometer depends on not only the mateiral of the carbon thermometers, but also the temperature range in which the carbon thermometer is used.
