It has DSP technology for crystal clear sound and an automatic volume control that keeps volume constant even when you move between quiet and noisy environments.

DSP 技术让它拥有高保真音质，而自动音量控制则让您感受到稳定的音量，即使穿梭于安静和嘈杂的环境之间。

Then we can take the derivative of that quantity, when we vary the temperature, holding the volume constant.

即恒定体积，改变温度，这里恒定温度下。

So the first path then, the first path, 1 constant volume constant V, so I'm going to, again, let's just worry about energy.

首先，是路径，等压过程。

I take V1 to V2 first, keeping the pressure constant at p1, then I take p1 to p2 keeping the volume constant V2 at V2. Let's call this path 1.

容易计算的路径，第一条路径，是首先保持压强不变,体积从V1压缩到。
