空气负氧离子浓度与主要气象因子拟合试验

Study on Curve Fitting of Aeroanion Concentration and Meteorological Factors

利用1年逐小时空气负离子浓度与同期空气温湿度、风速、降水量进行了拟合试验,结果表明:(1)空气负氧离子浓度与上述气象因子的相关并不是简单的线性相关;(2)与负氧离子浓度拟合方程的解释能力由强到弱依次为空气湿度、雨量、气温、风速;(3)与负氧离子浓度拟合方程的显著性水平由高到低依次为雨量、风速、空气湿度、气温;(4)与上述气象因子拟合显著性低于P≤0.05的显著性水平,说明还存在其他更重要的影响负氧离子浓度的因子。

After more than a year by hours air negative ions concentration and air temperature and humidity, wind speed, rainfall over the same fitting experiment, the results showed that： （1） air negative oxygen ion concentration is associated with the meteorological factors which is not simple linear correlation; （2）the relationship between the air negative ion concentration and the air temperature, the interpretation of the negative oxygen ion concentration equationis from the strong to the weak followed by the air humidity, the rainfall, the air temperature and the wind speed.（3） the significance level of the equation of fitting with the negative oxygen ion concentration israinfall, wind speed, tem- perature and air humidity; （4）the temperature of the meteorological factors was lower than that of P≤0.05, indicating that there were other more important factors influencing the concentration of negative oxygen ions.
