A total of 17 amino acids were determined , which mainly contained Gly, Arg, Leu, Lys, Asp et al.
A total of 17 amino acids were determined , and among them Gly, Arg, Leu, Lys, Asp were the main types.
這兩種說法正確嗎 哪種更準確呢？坐等 謝謝

兩個表達應該都對吧！只是第一個用從句，另一個沒有用。一點拙見，老師多多指教。
一般來說是第一種表達更好，如果只是主要包含這4種氨基酸，那et al就應該去掉
I would change "determined" to "have been found", then the second one is better. To say that sth contains ... means that all 17 acids contains all those elements inside them.
"determined"的個人主觀性較牽?/p>
語法沒錯誤嗎
不要沉 英語好的幫忙看看哦 看看語法對不對 急用
語法對的，你這個是研究論文那種嘛，已經(jīng)做的實驗就要用過去式
