In bottomheat mode, most of the movement of working fluid is pulsating and one-direction circulating flow, not random reciprocal oscillating in certain straight pipe or U-shaped pipe.
底加热时，热管内的运动多是循环的单向脉冲流动，并不是工质在某一个U型管或直管内的往复随机振荡。

The goal was simple: to discover how the species adapted to the kind of heat that can literally melt the bottom of shoes.
