水蒸气含量 meaning in English

water vapour content

Standard test method for water vapor content of gaseous fuels using electronic moisture analyzers
使用电子湿度分析仪测定气体燃料中水蒸气含量的标准试验方法
Since the distance from any given radar to each of these reflective surfaces ( which may be as much as 50km , or 30 miles , away ) is known precisely , the time it takes a beam to get there and back is a measure of how much water vapour it contains
因为可以精确获取某一雷达到这些反射物体中的任一表面的距离（可能有50公里，即30英里远），人们便可以通过雷达波往返两地所需的时间测得反射物的水蒸气含量。
The weather in east china , hot and humid , is quite different from that in scandinavia region . since the indoor environment is closely related to the outdoor natural condition , many conclusions on displacement ventilation drawn in other countries may not be suitable for applications in china . therefore , it is necessary to study further effect of the existence of water vapor on displacement ventilation and to analyze humidity control problems
已有的关于置换通风的研究大都是植根于欧美自然气候条件下进行的，而我国华东大部分处于亚热带地区，夏季炎热潮湿，这和北欧地区干燥的气候有很大的差异，有必要进一步研究空气中水蒸气含量对置换通风系统的影响以及与系统的湿度控制相关的问题。
