准确测量低温,特别是100开以下有时是十分困难的。安装于被测物体上的低温测温元件所指示的温度,几乎总高于稳定的实际温度值,其基本原因有三:1.测温元件受热辐射和热对流作用而被加热。如果测温元件还和另一个处于不同温度的物体
Accurate measurement of low temperature, especially below 100 to open the following is sometimes very difficult. The temperature indicated by the low-temperature temperature measuring element installed on the measured object is almost always higher than the stable actual temperature value for three basic reasons: 1. The temperature measuring element is heated by heat radiation and heat convection. If the temperature measuring element and another object at a different temperature
