| 摘 要： | 在钢筋混凝土结构的密闭暗房里,空气处于自然静态条件下,用1a时间检测房内空气正(n+)、负(n-)离子浓度,每天检测3次,每次15个数据,取平均值。全年的月平均值和一个月内的日平均值,n+和n-均在700～3200个/cm3之间表现波浪式变化规律,比房外400～550个/cm3高数倍;n+与n-的比值q=1.34。温度较高时离子浓度较高。

| Abstract: | Concentrations of air anion and cation are tested in a reinforced- concrete airtight darkroom without airflow disturbance over a period of one year. The annual average value and monthly mean value are obtained and compared to the concentrations of air ions outside the darkroom. It is concluded that static air ions result from Brownian motion. |

| Keywords: | air ions concentration rule of variation average value |
