气闸

Air pressure differentials should be such that there is no flow of air between the work area and the external environment or risk of contamination of outer clothing worn outside the area; f an air lock system for the passage of equipment, which is constructed so that there is no flow of contaminated air between the work area and the external environment or risk of contamination of equipment within the lock.

f 设备的进出要有气闸系统，其结构要保证没有工作区和外界环境之间污染空气的流通，或气闸室里的设备没有被污染的风险。

According to the requirements of the glass furnace, this system is proposed to use computer and PLC build up into one new control technique. Using this system, the technical requirements of varying of Petroleum, Pulverized Air and Exhaust Fume in the operation are guaranteed effectively. The system has overcome the disadvantage of the traditional control system.

本文针对玻璃熔窑运行过程中的要求，采用计算机控制技术与PLC组合成一新型的控制系统，快速准确地实现生产过程的控制，有效的保证了运行过程中重油、雾化气、助燃风及废气闸板的换向要求，以实现火焰换向的自动化控制。

The transient air gap magnetic fields under different conditions are also calculated and analyzed. The novel finite element method directly using magnetic induction as unknown variable has many advantage. It is analyzed theoretically in detail. Nonlinear eddy current field equations and finite element equations using magnetic induction as unknown variable are developed.

直线电机的磁场是一非均匀、非线性的涡流场，文中对非均匀磁场及材料的非线性进行了分析，提出了相应的解决办法，采用以向量磁位为求解量的传统有限元法，对不同合闸角下筒式复合次级圆筒型直线感应电机的瞬态特性进行了计算与试验分析，对不同条件下瞬态气隙磁场进行了研究。

It is different with the manual exhaust Slurry pumps valve is not required to run the wind man, it must be installed on the location of gas pipeline set point, the so-called water gas gathering point is the top horizontal tube of the highest point, this horizontal pipe 3 ‰ gradient requirements, does not allow for local conditions such as depression and bending, when the air into the valve, the valve automatically opens, the air removed, the water level rose, it will automatically close the valve, hot water can not spill, from a virtually eliminating Manual exhaust is not timely, easy to form a "vapor lock" effect caused by hot water heating effects and huge loss of the state.

它与手动排气闸阀不同点是不需要人为跑风，它安装的位置一定要在管路集气点上，所谓集气点就是顶层供水横管的最高点处，对此横管有3‰倾斜度要求，不允许出现局部凹陷和弯曲等情况，当空气进入阀体后，阀门会自动开启，调节阀空气排除后水位上升，它会自动关阀，热水不能外溢，从根本上消除了手动排气不及时，易形成"气阻"影响供热效果和造成热水大量流失的弊端。

Urban systems generally use a large number of low-pressure valve, and to environmental protection and development of energy-saving, that is, by the use of low pressure over the last steel valve towards environment-friendly plastic valve, balance valve, metal sealed butterfly valve and the center line butterfly valve seal transition, oil and gas to the pipeline of development projects, which in turn requires a large amount of flat gate valve and ball valve

2城建系统一般采用大量低压阀门，并且向环保型和节能型发展，即由过去使用的低压铁制闸阀逐步转向环保型的胶板阀、平衡阀、金属密封蝶阀及中线密封蝶阀过渡，输油、输气工程向管道化发展，这又需要大量的平板闸阀及球阀

Closing an airlock between a loading chamber and a plurality of process chambers arranged about an axis

关闭加料腔与多个按轴布置的工艺腔之间的气闸

The astronaut waited in the airlock until it was safe to enter the space station.

太空人在气闸舱内等候，直到能安全进入太空站。

Tests in the airlock later showed no contamination, and the spacewalk officially ended at

事后在气闸内进行的测试显示在宇航员身上没有受到氨水污染，此次太空行走正式结束时间为美国东部时间下午六点零九分

Because of the pressure inside there would be no need of airlocks or doors.

因为内部的压力，所以不需要气闸或门），故C是正确答案。

It involves the use of rooms with specially designed air handling, the existence of airlocks and/or sterilisers for the exit of materials and secure operating procedures.
