材料科學工程(化學)的問題!! 可以請高手幫我的忙嗎?

Two important differences between continuous cooling transformation diagrams for plain carbon and alloy steels are: 1) for an alloy steel, a bainite nose will be present, which nose will be absent for plain carbon alloys; and 2) the pearlite-proeutectoid noses for plain carbon steel alloys are positioned at shorter times than for the alloy steels.

本人幫閣下只因不喜歡老師單單抄題目，而要求學生認真做．既然老師可以抄，學生為何不可？話說回來，前幾次都沒有給我分數，這次若沒有，就請閣下自己努力好了．沒有免費的午餐．
