这个得根据这个语句所出现的场合来译,PSA是一个缩写,他有可能是就压吸附,这个PSA ROOM 可能就是吸附机房吧,当然PSA也可以是 美国摄影协会(photographic society of america),也可能是其它缩写,这都不一定,所以你最好把他出现的地方的整句话都写出来,可能会好明白是什么意思,另外这个缩写在前文一定出现过是代表什么的缩写。谢谢!
原文:
Inert Gas System:
A nitrogen production plant of the PSA type shall be installed The oxygen concentration can, if necessary, be lowered to a residual value of 0,1 vol. %. . The oxygenenriched gas released in the process with a medium concentration of about 30 - 35 vol. % O2 is blown into the atmosphere. After a 1-minute cycle the regenerated absorber is loaded with raw gas and the other absorber is regenerated.
