So, T ds is dx, dy.

所以Tds就是。

youdao

In other words, t surrounding ds has to be greater than zero, and of course temperature is always positive.

换句话说这就意味着，环境温度T乘以dS必须大于零，当然环境温度t是正的。

youdao

If it's a reversible process then the equality holds, but if it's irreversible, which means it happens spontaneously, t then ds is greater than this.

对于可逆过程，等号成立，但是如果是不可逆过程，这些不可逆过程是自发进行的，那么dS大于dq除以。

youdao

So then, just like we saw, analogous to what saw just before, dS/dp it's T dS/dp at constant T.

就像我们看到的,就像我们刚才看到的一样，结果是T乘以恒定温度下的。

SdT This has minus T dS minus S dT, but the dT part is zero because we're at constant temperature.

这一项包含负的Tds和，但是dT的部分等于零,因为温度为常数。

TdS It comes from the fact that dq reversible is T dS, pdV and dw reversible is minus p dV.

这个结论来自于：可逆过程下dq等于，做功dw等负的。

Fortunately, the devices are still compatible with normal DS games from outside China, though normal DS devices can't play games released by iQue.

Iwata expects the Revoltuion to help people make unique content like the DS. He hasn't hinted at what exactly will allow that to happen.

Since none of the five PCs we own has two VGA-out video ports (and we couldn't be bothered to track down a DVI adapter), we ended up hooking the DS-1500 up to both of our Media Center PCs.
