1. The harder rocks push against each other, the hotter they become; in other words, pressure itself, not only the rocks' properties, affects frictional heating. 岩石相互推挤得越厉害,它们就会变得越热;换句话说,不仅是岩石的性质,压力本身也影响摩擦加热。
2. So there is also a frictional force. 所以这个是摩擦力。
3. How does the frictional force do that? 摩擦力是怎么做的?
4. So I know what the frictional force is given by this result. 由此我得到,摩擦力的大小。
5. An alternative model ascribes the stream to frictional forces. 另有一种模型将气流归因于摩擦力。
