This process is called convection, and it's an efficient way of transferring heat.

这个过叫做对流，这是一种有效的传热方式。

And slowing down this huge Earth-sized heat transfer system would come with serious consequences.

减缓这个巨的地的传热系统会带严重的后果。

So we don't use that earlier equation to describe the heat transfer while a substance's phase is changing.

所以我们不使用前面的方述 物质相变过中的传热。

So that's our main mission here is who understand how the processes of combustion, heat transfer, and ignition all produce a spreading fire.

所以我们在这里的主要任务是了解燃烧、传热和点火的过是如何产生蔓延的火的。

This is a demo of slash pile burning that was part of an experiment that we did to look at factors influencing heat transfer into soil.

这是一个斜桩燃烧的演示，这是我们做的一个实验的一部分，这个实验旨在研究影响传热到土壤中的因素。
