The cable incorporates a tube for compensation of the ambient pressure.

该电缆采用了对环境的压力补偿管。

But in a higher ambient pressure, the flame-spread rates are independent of ambient pressure.

在较高压力下火焰传播速度对环境压力不敏感，即火焰传播速度几乎不随着压力变化。

Calculation method of viscosity for pure gas, mixed gas and liquid at ambient pressure is discussed.

介绍常压下纯气体及混合气体，加压下纯气体及混合气体以及液体粘度的计算方法。

The device is readily removed and installed at ambient pressure without venting the mass spectrometer.

该设备易于在环境压力下安装和拆除，而不用对质谱仪抽气。
