Molecular weight distribution (MWD)
Mandarin:
分子量分布 (fēn zǐ liàng fēn bù)
分子量分布 (fēn zǐ liàng fēn bù)
Explanation in English Language (EN):
The molecular weight distribution (MWD) describes the distribution of molecular weights in a polymer sample. Polymers typically consist of a mixture of chains with different lengths and, therefore, different molecular weights. The MWD can be determined through techniques like gel permeation chromatography (GPC). The MWD affects the properties of a polymer, such as its viscosity, melt flow, and mechanical properties.

Explanation in Mandarin (ZH):
分子量分布 (MWD) 描述了聚合物样品中分子量的分布。聚合物通常由具有不同长度、因此具有不同分子量的链的混合物组成。MWD 可以通过凝胶渗透色谱法 (GPC) 等技术来确定。MWD 会影响聚合物的性能，例如其粘度、熔体流动性和机械性能。
