把这一句，留给此刻的你
All I know is that these two gases both had a quite extraordinary effect, and that there was no respirator, and no protection against them that we knew of. So the soldiers would have been unable to protect themselves against this gas in any way.
我所知道的是，这两种气体都有非常特别的效果，没有呼吸器，也没有我们所知道的防护措施。所以士兵们无论如何都无法保护自己免受毒气的伤害。
