In other cases, the extra pathway can set up a reentry circuit.

还有一种情况，额外通路可建立起一个折返通路。

They can be caused by abnormal automaticity, reentry, or a triggered afterdepolarization.

可以由异常自律性、折返激动或被激发的后除极引起。

The plan involves developing a new spacecraft to safely guide the ISS during its final reentry through Earth's atmosphere.

该计划包括开发一种新的航天器，安全引导国际空间站最后一次重返地球大气层。

The vehicle will aim to guide the ISS through a final reentry into Earth's atmosphere.

该飞行器的目标是引导国际空间站最后一次重返地球大气层。

Then it will be all programmed to come back to Earth where it will burn up on reentry.

然后这个垃圾将会被程序带回到地球，在重新进入地球大气层时被烧毁。

NPR's Ted Robbins says most of the charges were illegal entry or illegal reentry into the U.S..
