relative molecular mass distribution

When polymer relative molecular mass and its distribution width are the same, the polymer displacement efficiency increases with the increment of the core permeability variation factor.

当聚合物的相对分子质量及其分布宽度相同时，随着岩心渗透率变异因数的增大，其聚合物驱采收率也随之增加。

The polyether polyols prepared by these DMC catalysts are of low unsaturation, high relative molecular mass, narrow molecular distribution compared with traditional KOH catalysts.

实验发现，用DMC催化剂合成的聚醚与用KOH催化剂合成的聚醚相比不饱和度低，相对分子质量高，相对分子质量分布窄。

It shows that the solution viscosity drops and the relative molecular mass reduces with narrow distribution.

结果表明改性栲胶溶液黏度下降，相对分子质量降低且分布集中。
