Let's hang on for a little while longer to a set of conditions where we will maintain constant entropy, namely constant entropy and pressure.

我们先继续考虑,保持熵不变的情况，即保持熵和压强不变。

But adding a constant velocity to objects does not change the fact that those which were maintaining constant velocity still maintain a constant velocity.

但是加上一个恒定速度并不会改变下述事实,即,那些正在匀速运动的物体,仍然保持匀速运动

Well that process of control to maintain a constant environment inside our body, whether it's an environment of constant mass or constant composition, or constant temperature, is called homeostasis.

这个控制过程维持着,体内环境的恒定,不论是内环境中物质的量的稳定,或者成分的稳定,或温度的稳定,这种状态叫做内稳态
