【摘要】 为了解决干旱地区缺水问题,采用施加正向空间电场的方法,使悬浮在气体中的雾粒荷电在静电力的作用下定向移动,迅速地积聚到作为阴极的土壤表面,同时也抑制了土壤水分蒸发,从而实现了空间电场的阴极聚水。为此,设计了一种电极电压、异极距和间歇工作节拍可调的空间电场聚水试验系统,研究了空间电场对土壤含水率的影响规律。初步试验结果表明,在气候条件比较干旱的情况下,在正向空间电场中的土壤水分蒸发明显要比在大气电场中的慢,说明了适宜的正向空间电场可以抑制土壤水的蒸发。更多还原

【Abstract】 Aims at solving the shortage of water in drought area, adopting the method of building the positive space electric field, making the suspended fog particles charge in the electric field moving and gathering toward the cathode ( the surface of soil), and keep the water of soil from vaporizing as well, thus form cathode polywater. In order to study the effect of space electric field toward the soil moisture contents, we design a system for cathode polywater. Its work time, voltage and the distance of two different electrodes can be adjusted. The research shows that when on the drought condition, the water of soil in space electric field vapors more slowly than in the air. It is well proved that positive space electric field can slow down the vapor of the water in soil .更多还原
