水蒸气压力 meaning in Chinese

water vapor pressure

Two typical examples analyses are conducted for the average conditions both of winter and summer climates under vapor diffusion and air leakage . a further discussion is set forth to determine the main factors that the moisture accumulation in wall is affected . it is found that the factors are the relative humidity at the wall surface , indoor temperature , permeability , air pressure difference and rate of the infiltrative or exfiltrative airflow
本文首先研究了墙体内的湿气迁移过程，详细分析了湿积累现象形成的原因，通过对夏、冬两季平均气候下墙内温度、水蒸气压力、相对湿度及湿积累在仅有扩散、扩散与空气渗透同时存在等情况所作的具体计算，发现墙内、外表面的相对湿度、室内温度、渗透率、空气压差以及空气的渗流速度是影响墙内湿积累的主要因素。
