在大气参数中折射率结构常数是一个重要的参数,有多种测量方法,其中利用温度脉动仪进行 测量是一个重要的测量方法。但是可以精确控制的微温度脉动源较难产生,所以至今还没一个标准的温度 脉动源对温度脉动仪进行定标。从热力学原理出发,采用绝热压缩和膨胀气体的方法,研制了一个温度可以 控制的温度脉动源装置,并且对其不确定度进行分析,认为这个装置可以用来标定温度脉动仪。

Refractive index structure constant is an important atmospheric parameter. There are many methods to measure , one is using micro-thermometer, but the precise controlled micro-thermometer source is difficult to be realized. Therefore, there isnt a standard micro-thermometer source for the calibration of the micro-thermometer until now. Based on the principle of thermodynamics, using adiabatic compression and expansion of gas method, a temperature controlled device is developed. The uncertainty analysis of the device is proved that the device can be used to calibrate micro-thermometer.
