| 摘 要： | 为研究城市小区域空气负离子的分布规律,以陕西科技大学西安校区内多处典型环境为测量样本,分别在不同天气条件和不同时间段进行测量.统计分析表明,天气由晴转雨时的空气负离子浓度会迅速提升;雨中,空气负离子浓度最大;室内空气负离子浓度远低于室外;中午,空气负离子浓度最高.研究认为,空气负离子浓度主要受温度、湿度、气流、水流、空气悬浮物等环境因子影响.

| Abstract: | In order to research for distribution regularities of air anion in small region of city, it is measured in different places of the Xi＇an campus of Shaanxi University of Science Technology at different times in different weather. The researches show that air anion con- centration increase quickly from a sunny to cloudy day and reach highest when it is rain. It is higher in the outdoor than room. In a day, air anion concentration is highest at noon except anthropogenic factor. In the last, it is proved that air anion concentration is affected by some environmental factors, for example： temperature, humidity, airflow, water flow, air sus- pension, and so on. |
