摘　　要：该文通过调节空间电场阴极聚水装置的异极距,采用测量泄露电流的方法,研究了不同异极距(1.5m、1.8m、2.1m、2.4m、2.7m)下,空间电场的分布规律。试验结果表明:在环境温度、湿度及高压直流电源电压一定的情况下,异极距不同时,空间电场分布曲线的形状相同,电极垂直(水平)距离相同处的泄露电流大小相同。在垂直方向电极垂直距离大约1 150mm处的泄露电流接近于零;在距电极线同一高度的水平方向上,泄露电流在电极线水平距离大约为1 500mm处接近于零;提出了空间电场在垂直方向上可分为电离区、中间区、逸散区3个区域,其中逸散区的大小影响土壤水份的蒸发、植物的蒸腾以及植物的生长。In this paper, by changing the heteropole distance of electric field in the cathode poly water device and using the method of measurement leakage current to study the distribution regularity of the electric field under different heteropole distance（ 1.5,1.8,2. 1,2.4,2.7 m）. The experimental results show that the heteropole distance not affect the shape of the distribution curve of the electric field at the same environmental temperature ,humidity and the HVDC power supply voltage, and the leakage current was the same at the same electrode wire distance. In the vertical direction the electrode wire was close to zero at the electrode wire distance approximately 1150mm; The same height with the electrode wire in the horizontal direction,the leakage current was close to zero at electrode wire distance approximately 1500mm; In this paper, electric field in the vertical direction for the three regions： ionization zone, middle zone, dispersion area, The size of dispersion zone had strong influence of soil water evaporation and plant transpiration and plant growth.
