在这一点上残留或灰尘微粒的控制，以建立或不重视热发动机部件或建立在石油以来的粒子悬浮在油。

At this point residue or dirt particles are controlled to not build up or attach to hot engine parts or build up in the oil since the particles are suspended inside the oil.

And these verbal descriptions lead to some pictures that I put up and I'll put up again about how you might try to accomplish something like run an engine or move heat from a colder to a warmer body.

这些言语的描述有助于你们理解我讲过的,而且还要再讲的一些物理图像,比如一台发动机,是怎么运行的,或热怎样从冷的物体传到热的物体。
