摘要:

全温域、全量程下空气湿度的测量一直是大气探测领域一个世界性的难题,露点仪以其独特的探测原理,能够在全温度量程内进行测湿,具有广阔的推广前景,但在实际中却一直没有实现业务化应用。文章在对当前国内外冷镜式露点仪发展现状详细介绍的基础上,详细论述了露点仪在业务化应用过程中需要重点解决的关键技术和问题。

Abstract:

Measurement of humidity in the full temperature and working condition is a difficult problem in the field of atmospheric observation all the world. Dew-point hygrometer can measure humidity in the full temperature field; however, it has not been put into operation application at present. In this paper, based on the analysis of the development of chilled-mirror dew-point hygrometer in China and abroad, the key technique problems in operation application are discussed in detail.

Key words: chilled-mirror dew-point hygrometer, temperature of dew point, thermoelectric cooling, photoelectric method
