此外，由于气体的分子运动依赖于温度，在木星行星的低温下，即使是最轻的气体也不可能获得逃逸所需的速度。

Also, because the molecular motion of a gas depends on temperature, at the low temperatures of the Jovian planets even the lightest gases are unlikely to acquire the speed needed to escape.

简单地说，如果气体分子达到逃逸速度，它就能从一颗行星上“蒸发”。

Simply stated, a gas molecule can "evaporate" from a planet if it reaches a speed known as the escape velocity.

通量管为太阳风等离子体向磁层输运和磁层粒子向行星际空间逃逸提供了通道。

The flux ropes offered channels for the transport of the solar wind plasma into the magnetosphere and the escape of the magnetospheric plasma into the interplanetary space.
