其原因是：黨政不分不是提高或加強了黨的領導，而是降低、削弱了黨的領導，黨政分開才能真正提高黨的政治領導的水平和質量；黨政不分使黨政分散了抓好自身建設的精力，只有黨政分開才能真正做到「黨要管黨」 ，使黨委擺脫各種繁雜事務的干擾，集中力量抓好黨建；黨政不分使黨委處於行政工作第一線，甚至成為矛盾的一個方面，黨政分開，可以使黨處在超脫的、駕馭矛盾和總攬全局的地位，從而發揮「總攬全局，協調各方」的領導作用；黨政不分使黨委自己成了行政工作的執行者，黨政分開才能使黨委真正能夠履行監督的職能。Calculation method of reducing water level equipment outflow for incomplete disturbance well
