在气象探测领域，温度传感器受到太阳辐射会导致其温度高于真实的大气温度，从而引起辐射误差。为提高测温精度，本文提出一种低辐射误差温度传感器设计，利用计算流体动力学方法（CFD）分析温度传感器在不同条件下的温度场分布情况。仿真实验结果表明：低辐射误差温度传感器具有较高的防辐射性能，其辐射误差低于传统温度传感器的辐射误差，银丝直径越小，辐射误差越低，有望降低辐射误差至0.05℃以内。

In the field of meteorological observation, when air temperature sensor is affected by solar radiation, the measuring result is greater than the actual temperature, which induces radiation error. In order to obtain high precision measurement, a novel temperature sensor with reduced radiation error was proposed and a computational fluid dynamics (CFD) method was used to analysis its temperature field distributions.The simulation results show that the radiation error of this new design is lower than that of traditional temperature sensor. The radiation error can be reduced in response to the reduction of the silver wires diameter. The radiation error can be reduced to below 0.05 ℃ by utilizing this technique.
