The efficiency score is a general indication of how close your operation is to the virtual input minimizer. 效率值代表你倉庫的運作離虛擬投入最小倉庫的接近程度。
In particular, the fuel exhibits a higher specific impulse, a measure of fuel efficiency that describes how much momentum a given weight of propellant can impart. 特別值得一提的是，甲烷的比衝量較高，這個燃料效率值代表特定重量的推進燃料所能產生的動量。
Calculate your personal efficiency ratio. 計算你的個人效率比。
Now we have achieved office automation, work efficiency is much higher than before. 現在我們也實現了辦公自動化，工作效率比過去高多了。
