Mandarin:
聚合度 (jù hé dù)

Explanation in English Language (EN):
The degree of polymerization (DP) is a fundamental concept in polymer science. It refers to the number of monomer units that are linked together in a polymer chain. The DP directly affects the molecular weight and properties of a polymer. Higher DP values generally lead to higher molecular weight, increased viscosity, and improved mechanical properties. The DP can be controlled through various polymerization parameters, such as monomer concentration, initiator concentration, and reaction time.

Explanation in Mandarin (ZH):
聚合度 (DP) 是高分子科学中的一个基本概念。它是指聚合物链中连接在一起的单体单元的数量。DP 直接影响聚合物的分子量和性能。较高的 DP 值通常会导致较高的分子量、增加的粘度和改进的机械性能。可以通过各种聚合参数来控制 DP，例如单体浓度、引发剂浓度和反应时间。
