In order to reduce the impact to the measurement accuracy of sensors inside the radiosonde by the changes of atmospheric temperature at different altitudes, the steady-state temperature field of the radiosonde in the high-altitude is analyzed by the finite element analysis software ANSYS. Successfully loading different loads by the ANSYS Parametric Design Language (APDL) , The temperature distribution of the radiosonde in the high-altitude and the heating time of heat loading inside the radiosonde could be obtained. Finally, a feasible temperature control strategy is proposed which is instructive to improve the internal environment temperature and design of the radiosonde.%为了减小探空仪内部的传感器件测量精度受外部大气温度随高度变化的影响,采用有限元分析软件ANSYS对探空仪高空中稳态温度场作了计算研究,并利用其中的参数化设计语言(APDL)实现了不同载荷的加载,获得高空中探空仪温度场的分布和其内部因加载热量后所需的升温时间,并得出了一种利于改善探空仪内部环境温度的可行温控策略.对于实际设计制作探空仪有着指导意义.
