1·In the process, oil is top gas (often reduced pressure), chemical is butadiene unit, the torch gas recovery system, oil and chemical are used.
工艺上用的，石油是塔顶气(常减压)，化工是丁二烯装置，火炬气回收系统，石油和化工均采用过。
2·Reduced Pressure Zone Assemblies must be inspected and tested periodically, in accordance with local codes, to ensure proper operation of check valves within the unit.
减压区总成必须按照当地有关规定定期检查和测试，以确保这种装置内的止回阀能够正常运行。
3·The solvent was evaporated under reduced pressure and water (100 ml) and acetic acid (12 ml) were added to the residue.
溶液减压蒸馏，在残留物中加入100毫升水和12毫升醋酸。
4·The single pressure sensor detects an actual reduced pressure at the tissue site.
单独的压力传感器探测组织部位处的实际 减压。
5·The concentration under reduced pressure brings short time of concentration and prevent the destruction of the effective content in the thermal sensitive material.
由于采用减压浓缩，故浓缩时间短，且不会破坏热敏性物料的有效成份。
