w we have the environment doing work on the system OK, now we've assumed that epsilon prime is greater than epsilon.

大于零，that，is，in，this，one,在这里环境对系统做功,好，现在我们假设,ε’比ε大。

OK, so w, first of all, work is being done to the system on the left hand side here.

好的，首先,我们通过左边对系统做功。

OK, any questions? All right, so we've described the system with these properties.

好，有没有问题？，好的，我们已经用这些性质描述了系统,这些性质。

OK, so that means heat is being imparted to the system, right, from the surroundings in a manner that compensates exactly the amount of work done.

好，这表示系统,从外界吸热,吸收的热量与系统,对外做功的值相等。
