查询词典 back seat

If the back-pressure valve counter-export access, back pressure will grow exponentially, bringing harm to the system and may be dangerous.

若背压阀进出口接反，背压将会成倍增加，给系统带来危害并可能发生危险。

Pairs of back-pressure valve prior to any maintenance, should stop functioning equipment, the release of pressure, close the back-pressure valve valves associated with the system, while recognizing that there is no pressure pulsation damper.

对背压阀进行任何维护以前，应停止运转设备，释放压力，关闭背压阀与系统相联的阀门，同时确认脉动阻尼器内没有压力。

And pulsation damper used simultaneously, the pulsation damper to be an in between pumps and back-pressure Bellows Seal Valves valve in order to absorb the pump and back-pressure valve between the flow peak.

与脉动阻尼器同时使用时，脉动阻尼器应安在泵与背压阀间，以吸收泵与背压阀间的流量峰值。

Warning: The back-pressure valve prior to any maintenance, equipment operation should be stopped, release the pressure, close the back pressure valve valve associated with the system, while recognizing that there is no pressure pulsation damper.

警告：对背压阀进行任何维护以前，应停止运转设备，释放压力，关闭背压阀与系统相联的阀门，同时确认脉动阻尼器内没有压力。

For the stability of the flow metering pumps, metering pump flow rate, as some big changes with pressure, you can set the exit of metering pump back-pressure valve, so that the output of metering pump flow rate stability, and then usually selected back-pressure valve The Reducing Valves pressure of the actual use of a metering pump metering pump pressure or slightly less than the use of pressure.

用于稳定计量泵的流量，如某些计量泵的流量随压力变化较大，可在计量泵的出口处设置背压阀，使计量泵的输出流量稳定，这时一般选择背压阀的压力为计量泵的实际使用压力或略小于计量泵的使用压力。

If the back-pressure valve ANSI Bellows Seal Gate Valves counter-export access, back pressure will be doubled, bringing harm to the system and may be dangerous.

若背压阀进出口接反，背压将会成倍增加，给系统带来危害并可能发生危险。

On the back-pressure DIN Y-Strainers valve prior to any maintenance, equipment operation should be stopped, release the pressure, close the back pressure valve valve associated with the system, while recognizing that there is no pressure pulsation damper.

对背压阀进行任何维护以前，应停止运转设备，释放压力，关闭背压阀与系统相联的阀门，同时确认脉动阻尼器内没有压力。

Warning: The back-pressure valve prior to any maintenance, should stop functioning equipment, the release of pressure, Plug Valves close the back-pressure valve valves associated with the system, while recognizing that there is no pressure pulsation damper.

警告：对背压阀进行任何维护以前，应停止运转设备，释放压力，关闭背压阀与系统相联的阀门，同时确认脉动阻尼器内没有压力。

Though, to achieve both at the same time is not easy, otherwise Chinese wouldn't have invented the back-scratcher, a tool with which one can scratch his own back.

不过，这也不是一个容易的事情，要不然怎么中国人要发明那种自己挠自己背的老头乐呢？

Among the analysis methods, back-titration with Ca 〓 was adopted other than direct-titration or back-titration with NaOH. Because Ca 〓 method is carried out in acidic condition, in which the hydrolysis of ester-linkages could be neglected.

该法的分析测定是在酸性条件下进行的，多羧酸纤维素酯在酸性条件下基本不水解，可以忽略酯键存在对测定结果的影响。

More direct, directer ; most direct, directest
