双温双压法湿度测量不确定度的综合评定

基于双温双压法的湿度发生过程受到温度、握力、饱和度、增强因子等多种因素的影响，如何解决各参数之间的耦合问题，并将所有因素引入湿度测量不确定度评定模型是提高湿度测量准确度的重要方法。详细分析了增强凶子和饱和器的饱和度对实验舱湿度的影响，提出一种完整的评定模型及解算方法，并通过实例说明该模型的应用及其对评定结果的影响。

The General Evaluation of the Humidity Measurement Uncertainty Based on Two-temperature and Two-pressure Method

Humidity generating based on Two-temperature and Two-pressure method could be affected by temperature, pressure, saturation and enhancement factors and so on, it must be effective method of raising the accuracy of humidity measurement to deal with coupling of all factors and construct a model used in the evaluation of the humidity measurement uncertainty including all factors. An integrated model is introduced together with the solution with the analysis of the influences on the humidity of the artificial climate box caused by enhancement factors and saturation in detail, whose application is known to us with an example, as well as the influence on the evaluation.
