| 摘 要： | 研究了在自然条件下温度、湿度和温湿度同时改变时空气负离子浓度的变化规律。实验表明,湿度对负离子浓度有明显作用,随湿度逐渐升高(相对湿度10%～80%),负离子浓度从200个 cm3升至8000个 cm3以上,负离子浓度上升的幅度随湿度增加逐渐增大;负离子浓度也随温度升高而升高(在5～40℃之间);温湿度同时变化时,负离子浓度变化率增大。

| Abstract: | The ion concentration in the air is closely correlated with the environment.The variation rules of negative air ion concentration with the change of temperature,humidity or simultaneous change of temperature and humidity were studied under natural conditions.It was found that the negative ion concentration rose quickly with the increasing relative humidity(RH) and it could change from 200 ions/cm~3 to above 8 000 ions/cm~3 when humidity gradually increased(RH:10%～80%).The negative ion concentration also went up with temperature rising(5～40 ℃).The variations of concentration were even greater with simultaneous increase of temperature and humidity. |
