As a result, the number of OH radicals increases with the intensity of electric field and the density of watervapor molecules.
电场强度的增强和适当增加水蒸气分子的密度有利于OH自由基的生成。

Thought water is a good refrigerant, it is difficult to be used directly in a common compression refrigeration system due to its very low pressure and vapordensity at the evaporation temperature.
