back-to-back test

基本解釋

Modern thyristor valves for HVDC are of high power rating and difficult to be tested in a conventional back-to-back test circuit.
現(xiàn)代晶閘管閥的大容量使得難以采用傳統(tǒng)的背靠背試驗回路對其進(jìn)行運行試驗。
Modern power thyristor valves have a high power rating and are difficult to be tested in a conventional back-to-back test circuit.
現(xiàn)代晶閘管閥的大容量使得難以采用傳統(tǒng)的背靠背試驗回路對其進(jìn)行運行試驗。
However, this synthetic test circuit offers several technical advantages and is superior to the Back-to-Back direct test circuit in terms of economy as well.
然而，這種合成試驗回路更具有技術(shù)上的優(yōu)勢，并且在經(jīng)濟上也優(yōu)于背靠背直接試驗回路。

With production estimated to take at least two weeks to get back to normal, the test-flight programme of Boeing's 787 Dreamliner will have to be pushed back (again).
