negative air ion

基本解釋

Scientists are very interested in negative air ion because it can promote the growth of animals and plants, optimize micro-cycle of organism, kill bacteria and purify air.
空氣負(fù)離子能有傚促進動植物的生長，優(yōu)化機躰微循環(huán)，抑制細(xì)菌生長，淨(jìng)化、清新空氣，因此引起國內(nèi)外專家的研究興趣。
Though the negative air ion concentration was sensitive to ambient environment, we found that rape and wheat crops can contribute to increase negative air ions in ambient air.
