As a result, the number of OH radicals increases with the intensity of electric field and the density of water vapor 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 vapor density at the evaporation temperature.
由于水的蒸发压力低、比容大使得水作为制冷剂直接用于压缩式制冷系统还有很大的困难。
