/etc/nginx/nginx.conf.这个装置可以防倒吸吗?除了防倒吸,可以向上排气收集气体吗?忽然想起来了，是不是加上瓶塞就可以防倒吸和收集气体了？
清枫品撯漀
这个装置不可以防倒吸.不可以向上排气收集气体（按照气体流的方向） 加上瓶塞：没有作用,不可以防倒吸,但可以向下排空气收集比空气重的气体.但不可以收集轻的气体,就是向上排空气法（不可以）.

这个装置丝毫作用都没有，即不能收集重的气体也不能收集轻的气体。氢气收集只能是向下排空气法。
倒吸的原因是因为气体大量溶解，使得装气体的容器内压强降低，倒吸液体（水）。要是HCl气体先经过CCl4是不会被吸收的，那么装氯化氢气体的容器内压强就不会降低，那么就不会倒吸。这个装置可以向上排气收集气体，但不能防倒吸。
