high compression ratio pump

基本解釋

• [能源科學(xué)技術(shù)]高壓縮比泵
• [物理學(xué)]高壓縮比泵

英漢例句

雙語(yǔ)例句

• As the Roots pump is a non-vacuum inside the compression, the compression ratio is usually very low, so high, medium and vacuum pumps need to pump before.
  由於羅茨泵是一種無(wú)內(nèi)壓縮的真空泵，通常壓縮比很低，故高、中真空泵需要前級(jí)泵。
• But there are some shortage of ordinary single-stage heat pump in low-temperature environment, such as high compression ratio, devoid heating power and low efficiency.
  但普通單級(jí)空氣源熱泵熱水器在低溫環(huán)境下運(yùn)行中存在壓縮比過(guò)大、制熱量不足和制熱傚率太低等問(wèn)題。
