I also want to assume for our present purposes that there's only pressure volume work going on, which is to say I want to put pdV p dV in here minus p dV for dw.

同时假定,对于我们目前的目的而言，只有压强做功这就是说,我要把这里的dw替换为负。

And the cycle it's going to undertake is called a Carnot cycle, and it works the following way: we're going to do pressure volume work.

它的循环过程，叫做卡诺循环，过程如下：，这是个压强体积系统。

Increased blood volume makes your heart work harder to move more blood through your blood vessels, which increases pressure in your arteries.

血量的增加将加重心脏负担，血管内的血量也会随之上升，进而加大动脉的压力。
