| 为了提高露点温度的测量准确度，寻找不同露点温度对应的最佳变化量，设计并进行了光电信号特征参数试验。使用自主研制的精密露点仪，调整不同的电压变化量对露点温度进行测量，将测量数据与MBW373型参考精密露点仪采集得到的数据进行对比，并计算误差，得到-30 ~ -10 ℃温度区间内的光电信号特征参数与露点温度对应的关系表，分析得出该温度区间的光电信号特征参数，证实了光电信号特征参数试验方案的可行性，为之后进一步研究露点测量过程提供了数据参考和理论支撑。 |

| In order to improve the measurement accuracy of dew point temperature and find the optimal change corresponding to different dew point temperatures, the characteristic parameter test of photoelectric signal was designed and conducted. The test uses a self?developed precision dew point meter to adjust different voltage changes to measure the dew point temperature, and MBW373 cold mirror precision dew point meter as the reference. Then, the collected data was analyzed and the error was calculated. Finally, the relationship table between the photoelectric signal characteristic parameters and the dew point temperature in the temperature range of -30 ~ -10 ℃ was obtained, and the photoelectric signal characteristic parameters in this temperature range were analyzed, which confirmed the feasibility of the test scheme. It provides data reference and theoretical support for further research on the dew point measurement process in the future. |
