Wiki上關(guān)于pig的解釋中,其中一條是:
(engineering) A device for cleaning or inspecting the inside of an oil or gas pipeline, or for separating different substances within the pipeline. Named for the pig-like squealing noise made by their progress. 參見(jiàn)http://en.wiktionary.org/wiki/pig
粗譯:(工程領(lǐng)域)一種用于清理或者檢測(cè)油氣管道設(shè)備,或用于分隔管道內(nèi)不同的介質(zhì)。因其在操作過(guò)程中產(chǎn)生類似于豬的振鳴聲而得名。
