優化!優化!/ reverse-engineered

The local government asked a university’s sports department to lend it an old German-made bobsled, which members of Mr. Hosogai’s group then reverse-engineered. Within two weeks, they had made their own parts, which they said were stronger than the German ones because they were shaped from single pieces of steel, instead of welded from separate pieces.
當地政府請求一所大學的體育系把他們的一架德國製造的舊雪橇借給細貝的團隊，隨後他們將其拆開，以便倒序製造雪橇。兩周內，他們造出了自己的部件，他們說這些部件比德國造的更堅固，因為是用整塊鋼材塑造的，而不是用分別製造的零件焊接而成的。

Beijing will also give room to China's refining industry to pass on the cost to consumers, according to the statement on the State Council's website. China strictly controls fuel prices, which limits the ability of refining companies to easily pass on the cost of refinery and antipollution upgrades to consumers. 

中國國務院網站上的這則聲明顯示﹐北京還將給中國煉油業一定空間﹐使其可將成本轉給消費者。在中國﹐燃油價格受到嚴格控制﹐因而對煉油企業產生一定限制﹐無法輕易將煉油廠升級改造和優化治污措施的成本轉嫁給消費者。( WSJ)
