摘要

由于空气湿度与大气压有关

在高原地区计算空气湿度时

如果仍用GB311—83和IEC标准中提供的湿度图读取湿度值

将带来不能允许的误差.本文介绍了准确计算空气湿度的公式组和一个修正公式

此修正公式附加于标准湿度图读数可以快速简便地得到准确的空气绝对湿度值.为了保证湿度测量的准确度

干球和湿球温度计的读数误差应分别控制在±0.5℃和±0.2℃以内.

Abstract

As the air humidity is related with atmospheric pressure

an imper-missible error will be caused to the humidity value if using the humidity diagram in GB311 -83 and IEC standards to calculate the humidity in high - altitude areas. This paper introduces a formula group and a correction formula to calculate the hu-midity accurately. Using the correction formula in combination with the standard humidity diagram

an accurate absolute humidity can be gained in a quick and simple way. In onder to ensure the accuracy of humidity measurement

the error of dry -and wet bulb thermalmeters should be controlled within the range of ±0. 5℃ and ±0. 2 ℃ respectively.
