And when it's deorbited, it basically acts in the same way that a meteoroid does.

当它们脱离轨道时，行为基本上与流星相同。

One of the reasons none of this typically presents a danger is that when satellites reach the end of their useful lives, they can be deorbited in a controlled way, sent on suicide dives to the middle of the ocean.

但这些因素通常并不会带来危险，原因之一在于卫星的有效寿命接近尾声时，人们可以控制它们脱离轨道的方式，将它们以自杀式飞扑的方式送入茫茫大海。
