reduction 是"还原"还是"降低"?

FR level(阻火剂用量)一栏中的 3 parts reduction/6 parts reduction(parts为份数)

倾向于还原

从后面的数据看,密度比标准的还大,所以不会是稀释吧。

Sorry, 刚才没看懂你的数据。

《英汉大辞典》:

6. 浓缩变稠【应该是这个吧?】

7. 稀释

实在头大

稀释---dilute
浓缩--concentrated
所以暂定为“还原”,因为有的表面活性剂活性太大,在一般条件下会发生反应,所以产品要溶解在其它化学品中,用的时候再还原。

I don't think it is "huanyuan"

"Huanyuan 还原" ( = reduction) is a chemical reaction, the opposite of oxidation.

Here I think it refers to a process that is similar to "reduction" (稠化?)in cooking, such as in making hong2 shao1  rou4, the final step of which is to boil the sauce down (reduction) to make it thicker and more concentrated.
