Number-average molecular weight (Mn)
Mandarin:
数均分子量 (shù jūn fēn zǐ liàng)
数均分子量 (shù jūn fēn zǐ liàng)
Explanation in English Language (EN):
The number-average molecular weight (Mn) is a way to express the average molecular weight of a polymer sample. It is calculated by summing the molecular weights of all the polymer chains in the sample and dividing by the total number of chains. Mn gives more weight to the smaller chains in the distribution.

Explanation in Mandarin (ZH):
数均分子量 (Mn) 是表示聚合物样品平均分子量的一种方法。它是通过将样品中所有聚合物链的分子量相加，然后除以链的总数来计算的。Mn 对分布中较小的链赋予更多权重。
