And there were hundreds of release mechanisms on the sunshield that all had to release at just the right time in just the right way.

遮阳罩上有数百个释放机制，它们都必须在正确的时间以正确的方式释放。

There were quite a few single point failures so that if one release mechanism didn't work, there would be nothing we could do to fix it.

有很多单点故障，所以如果一个发布机制不起作用，我们将无能为力。

One of the main threats was the German tanks,   so the Russians decided to train dogs to run bombs under the tanks, bite a release mechanism  that dropped the bomb, then return to the ranks.

主要威胁之一是德国坦克，因此俄罗斯人决定训练狗在坦克下方运行炸弹，咬住投下炸弹的释放装置，然后返回队伍。
