1. The power maximum (for) thick film is 63% which is more than three times that (of) thin film.
Q: 為何前面用for 而後面用of。前面可以用of嗎?若可以 語意上的差別為何?

A: 兩處用for或of皆可通用, 語意有細微差異, 在於介系詞本身的意思.


2. The device characteistics under light (for) three devices with different concentrations have been shown in Fig.......
We compare the device characteristics (of) three devices with different concentrations ....

Q: 為何前面用for 而後面用of。前面可以用of嗎?若可以 語意上的差別為何?

A: under light(在光線下)是外加的副詞片語, 但因為light本身是名詞, 如果用of, 會被誤解成"在three devices的光線下", 所以不可用of.

後句必須用of語意才明確, 因為若是用了for, 會與動詞compare「來電」形成動詞片語, 造成語意的誤解.
