Dispersity
Mandarin:
分散度 (fēn sàn dù)
分散度 (fēn sàn dù)
Explanation in English Language (EN):
Dispersity (Đ) is a measure of the distribution of molecular weights in a polymer sample. It is defined as the ratio of the weight-average molecular weight (Mw) to the number-average molecular weig 1 ht (Mn). A dispersity of 1 indicates that all polymer chains in the sample have the same molecular weight (monodisperse). Higher dispersity values indicate a broader distribution of molecular weights. Dispersity affects the properties of a polymer, such as its viscosity, melt flow, and mechanical properties.

Explanation in Mandarin (ZH):
分散度 (Đ) 是衡量聚合物样品中分子量分布的指标。它定义为重均分子量 (Mw) 与数均分子量 (Mn) 的比率。分散度为 1 表示样品中的所有聚合物链都具有相同的分子量（单分散）。较高的分散度值表示更广泛的分子量分布。分散度会影响聚合物的性能，例如其粘度、熔体流动性和机械性能。
