respectively 用來修飾句中後面的 items, 說明跟前面 items 的關係時, 一般不用逗號間隔.
The cups and saucers cost 5 and 3 respectively.
兩樣東西, 各自不同價錢

但有些時候我們只有一句主詞:
The weights of the two experts are 0.600 and 0.400, respectively.
此時 respectively 就不是用作修飾後面兩個 items, 而是統觀地補充了整句句子的意思.
此句中的 respectively 可以省略.

假如我們分開兩個主詞, 就要寫成:
The weight of the expert A and the weight of expert B are 0.600 and 0.400 respectively.
這時候就不需要 逗號了！

Dan and Don are dumb and dumber respectively.

Her first and second sons were named Mark and Anthony respectively.

The values of prostaglandin, EP-12, and catechin in the cholesterol-treated and control groups were 12.6, 4.8, and 3.2, respectively.

用不用逗號主要是看句子的結構跟複雜程度˙

假如句子不是很複雜˙ 不用逗號也可以˙ 頭兩句是簡單句˙

假如句子結構比較複雜˙或數要表達的內容複雜˙ 那就用逗號加強清晰度˙ 第三句比較複雜˙
