| 中文摘要: |
| 露点仪测量气体湿度过程中，拉乌尔效应对测量准确性影响很大。使用测量凝结物冰点值估算拉乌尔效应影响值，发现在冷镜表面滴入酒精吹扫并加热蒸发残留酒精清洁表面，可以大大减少拉乌尔效应影响。通过实验可以减少拉乌尔效应露点误差到0.1℃以下。 |
| 英文摘要: |
| The Raoul effect makes a great influence on the accuracy of measuring dew point of gas using a hygrometer. When estimating the Raoul effect by measuring condensate freezing point, we found drops of alcohol on the cold mirror for blowing and heating evaporation residue alcohol to clean the surface can greatly reduce the Raoul effect. It can reduce the Raoul effect’s error of dew point temperature to less than 0.1℃. |
