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

这个过程叫做对流，这是一种有效方式。

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

减缓这个地球小系统会带来严重后果。

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

所以我们在这里主要任务是了解燃、和点火过程是如何产生蔓延火。

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.

这是一个斜桩燃演示，这是我们做一个实验一部分，这个实验旨在研究影响到土壤中因素。

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方程来描述 物质相变过程中。
