Weight average molecular weight
Mandarin:
重均分子量 (zhòng jūn fēn zǐ liàng)
重均分子量 (zhòng jūn fēn zǐ liàng)
Explanation in English Language (EN):
The weight average molecular weight (Mw) is a way to express the average molecular weight of a polymer sample. It is calculated by summing the products of the molecular weight of eac 1 h chain and its weight fraction in the sample. Mw gives more weight to the larger chains in the distribution. Mw is often used in conjunction with the number average molecular weight (Mn) to characterize the molecular weight distribution of a polymer.

Explanation in Mandarin (ZH):
重均分子量 (Mw) 是表示聚合物样品平均分子量的一种方法。它是通过将每条链的分子量与其在样品中的重量分数的乘积相加来计算的。Mw 对分布中较大的链赋予更多权重。Mw 通常与数均分子量 (Mn) 一起使用来表征聚合物的分子量分布。
