**（或霜點）溫度：指空氣在水汽含量和氣壓都不改變的條件下，冷卻到飽和時的溫度。形象地說，就是空氣中的水蒸氣變?yōu)槁吨闀r候的溫度叫**溫度。**溫度本是個溫度值，可為什么用它來表示濕度呢？這是因為，當空氣中水汽已達到飽和時，氣溫與**溫度相同；當水汽未達到飽和時，氣溫一定高于**溫度。所以**與氣溫的差值可以表示空氣中的水汽距離飽和的程度。 </p> <p> 改變已知濕度氣體（主要是指飽和濕氣）狀態(tài)的方法。我們知道，氣體的狀態(tài)由壓力、溫度和體積來確定，對于飽和濕氣，如果狀態(tài)條件不變，那末水汽的含量是恒定的，反之，若狀態(tài)改變，水汽含量亦隨之改變。于是可以利用熱力學 P 、 v 、 T關系配制出所要求的濕度的氣體，基于這一原理的方法有改變壓力的方法，即雙壓法；改變溫度的方法，即雙溫法；以及同時改變壓力和溫度的方法天津濕度發(fā)生器分類</p><p
