跟踪式热平衡温度测量

Temperature Measurement by the Method of Tracking Type Heat balance

介绍了跟踪式热平衡温度测量的原理：当检测头与被测体靠近时，通过对流换热形成梯度为零的温度场，因而二者温度相等。这种梯度为零的温度场是通过对检测头的一端制冷（或加热）跟踪被测体的温度形成的．最后给出了静态和动态实验的测试结果。

This paper introduces the principle of temperature measurement by themethod of tracking type heat banlance. When a detecting headis close to a measured object,auniform temperature field with no gradient will form through heat convection. Therefore,their temperature is equal.The uniform temperature field with no gradient is formed by re-frigerating(or heating)one side of the detecting head,and tracking the temperature ofmeqsured object.To end with,the static and dynamic test results are given.
