事实上，在太阳风——一股不断从太阳上吹落的带电粒子流——的影响下，太阳的质量一直在下降。

Actually, the Sun is constantly losing mass through the solar wind, a stream of charged particles constantly blowing off the Sun.

最终的结果是一股持续的气体流，开始是星系间的热气体，结束时是一股被称为“冷却流”的少量冷气体，落入星系中央。

The net result is a continuous flow of gas, starting as hot gases in intergalactic space and ending as a drizzle of cool gas called a "cooling flow," falling into the central galaxy.

当这些负电荷距离地面不到100米时，会遇到一股来自地面的正电荷粒子流。

When a stream of these negatively charged electrons comes within 100 meters of the ground it is met by a stream of positively charged particles that comes up from the ground.
