如果蒸汽干燥或则含有气体，它将无法凝结导致效率降低。
If the steam is dry or contains gas then it cannot condense and its effectiveness is reduced.
如果输送液体含有气体，该系列的泵机可内置或外置排气装置，以保证输送稳定。
If the liquid contains gas or air the pump can be modified with either internal or external gas removal construction which stabilizes the operation.
和隔膜泵相比，单螺杆泵可输送各种混合杂质，含有气体及固体颗粒或纤维的介质，也可输送各种腐蚀性物质。
And diaphragm compared to single-screw pump can transport all kinds of mixed impurity containing gas and solid particles or fibers of the media, but also transport all kinds of corrosive substances.
由于在泡沫水泥中含有气体，其中气体参数又是温度和压力的函数，因此在固井施工设计中不能采用常规固井理论进行相关计算。
Because foamed cement has gas and the properties of gas are the function of pressure and temperature, the conventional cementing theory can not be used in cementing with foamed cement.
