同时温度控制是PCR的关键技术之一，也即是PCR芯片的关键技术。

At the same time temperature control is one of the keys of PCR technology, which is of PCR chip.

缩小地同时温度变得更得高，这样就加剧了太阳外层的燃烧并使其膨胀。

When it contracts the core will get hotter, which will heat up the sun's upper layers and make them expand.

然而现在，一种新型的钢已经被开发出来，它可以在更低的温度下抵抗断裂，同时保持其强度和韧性，而不需要昂贵的添加剂。

Now, though, a novel type of steel has been developed that resists fractures at much lower temperatures, while retaining its strength and toughness—without the need for expensive additives.

What that means is we want to run the hot reservoir as hot as possible and the cold reservoir as cold as possible.

也就是说我们希望高温热源温度尽可能高,同时低温热源温度尽可能低,从原理上说。

V2 So, if one goes to two and V1 goes to V2, and it's constant temperature, just what we've specified there.

如果状态1变到状态1并且体积从V1到，同时温度保持不变，这就是我们这里要讨论的问题。

You could take a continuous path, where you have an infinite equilibrium points in between the two, a smooth path, whereyoudrop pressureand temperature simultaneosly in little increments.

你可以选择光滑的连续路径，在初末态间有,无数个平衡态的点，压强和温度同时一点,一点地下降。
