| 摘 要： | 用核磁和计算机模拟两种方法研究了梯度共聚物的结构量(组成,三元组浓度,序列长度分布)的瞬时值与累积值之间的关系,通过这两种方法验证了组成的瞬时值与累积值之间的传统关系式同样适用于三元组浓度、序列长度分布的瞬时值和累积值间的关系,梯度共聚物结构量的瞬时值和累积值可用此关系式关联.

| Abstract: | We adopt NMR and simulation into research of the relationship between instantaneous structural factors of gradient copolymers(composition percents,sequence length distribution,triad concentrations) and accumulated values.The traditional relationship of composition percents between instantaneous values and cumulative values could be extended to sequence length distribution,triad concentrations.So the instantaneous structural factors of gradient copolymers and cumulative structural factors could be connected by the equation. |

| Keywords: | gradient copolymer instantaneous structural factors cumulative structural factors triad concentration sequence length distribution |
