实践证明这种控制模式能够较好地实现中继气体加压站稳压供气和节能运行。

The practice shows this control method can achieve stable mixed gas supply and ensure the economic running for relay gas pressing station finely.

为了大幅度降低触点的氧化，玻璃管内的环境往往是采用不含氧气的气体加压的。

In order to reduce the oxidation of contacts greatly, the environment inside the glass tube is often pressurized with a gas that contains no oxygen.

I'm pressing on the gas. So I expect that to be a positive number. The pressure is constant 0 p. The V goes from V1 to zero.

我们对气体加压,所以这应该是一个正数,压强是常数，p，V从V1变成。
