. 溫度一低 ,生長速率就慢下來。 1) It has been shown that climb milling results in better surface finish. 已經(jīng)表明 ,順銑可以獲得較好的表面光潔度。 4) It is apparent that the design engineer is a vital factor in the manufacturing process. 很明顯 ,設(shè)計工程師在制造過程中起主要作用。 1. Pig iron is an alloy of iron and carbon with carbon content more than 2 percent. 生鐵是一種鐵碳合金, 其含碳量在百分之二以上 。 四、狀語分譯 當(dāng)原文的狀語太長或不宜譯成漢語的狀語時,可將其分譯成小句。 2.這種坐標(biāo)繪圖儀能在本身的工作范圍內(nèi)定出一點的位置, 精確到 。 10.鉆床 除了用來鉆孔以外 ,還可加工許多零件。 6. 在學(xué)生開始做實驗之前不久 ,他就把所有儀器都放在桌子上。 3) The head of a drilling machine is mounted on the column above the table. 2) Not having been discovered, many laws of nature actually exist in nature. 雖然自然界的許多規(guī)律尚未發(fā)現(xiàn), 但它們確實存在于自然界中 。 3. The flexibility and versatility of numerical control have led to the development of a new type of machine tool called the machining center. 數(shù)控系統(tǒng)的靈活性和多用性導(dǎo)致一種新型機(jī)床的發(fā)展, 這種機(jī)床叫做加工中心 。 試比較:一個物體的重量已被發(fā)現(xiàn)在地球上因地而異。 3) It should be noted that the life of the cutting tool is most affected by the cutting speed. 2) It is obvious that a greater force should be applied to start a motorcar than a motorcycle. 顯然 ,開動一輛汽車比開動
