The results show that the number of OH radicals decreases rapidly and the number of o atoms follows a rule of increasing firstly and then decreasing from arc root to arc tip.
结果表明:沿等离子体从弧根到弧梢位置,OH自由基数量迅速减少,O原子数量呈现先增多后减少的规律。
As a result, the number of OH radicals increases with the intensity of electric field and the density of water vapor molecules.
