Z-average molecular weight (Mz)
Mandarin:
Z 均分子量 (Z jūn fēn zǐ liàng)
Z 均分子量 (Z jūn fēn zǐ liàng)
Explanation in English Language (EN):
The Z-average molecular weight (Mz) is a higher-order average molecular weight that gives even more weight to the larger chains in the distribution compared to the weight average molecular weight (Mw). It is calculated by summing the products of the molecular weight of each chain, its weight fraction, and its molecular weight squared, and then dividing by the sum of the products of the molecular weight of each chain and its weight fraction. Mz is more sensitive to the presence of high-molecular-weight chains in the sample.

Explanation in Mandarin (ZH):
Z 均分子量 (Mz) 是一种高阶平均分子量,与重均分子量 (Mw) 相比,它对分布中较大的链赋予更多权重。它是通过将每条链的分子量、其重量分数及其分子量的平方的乘积相加,然后除以每条链的分子量与其重量分数的乘积之和来计算的。Mz 对样品中高分子量链的存在更敏感。
