It seems very unlikely that large portions of the nebula were heated to such extreme temperatures, and huge nebula areas could not possibly have lostheat so fast.
星云的大部分都被加热到如此极端的温度似乎是不太可能的，而巨大的星云区域不可能这么快就失去热量。

If adopted, heat pipes can recover lostheat so as to save energy.
如果采用热管换热技术，对余热进行回收，可达到节能的目的。

The faster that water moved past a filament, the quicker the filament lostheat.
