查询词典 weight

The molecular weight and molecular weight distribution of polyethylene were determined by GPC and Viscometry.

对GPC曲线的高斯函数拟合分峰，计算在双组分茂金属催化体系中每种催化剂得到的聚乙烯的重量之比；根据各催化剂的催化活性和按所加的催化剂的摩尔比例假定进行独立反应时，可以计算在双组分催化体系中每种催化剂得到的聚乙烯的重量之比；根据两种重量之比的比较结果和对双组分茂金属催化体系得到的聚乙烯的平均分子量和平均分子量分布的分析结果，可以推测在催化体系CatZr〓/CatZr〓中两种催化剂基本上不存在相互作用；而在CatZr〓／CatZr〓体系中两种催化剂之间可能有相互作用存在。

A Novel Method for Intrinsic Viscosity Determination of Polymer SolutionThere are many methods for molecular weight determination of polymers, among which viscometry is used most, it has been broad applied both in production and scientific research. This method is easy to operate with simple instruments and is applicable for broad-range molecular weight, additionally, it has high precision.

在许多情况下，常需要对同种类聚合物的特性粘度进行大量重复测定，如果都按此法操作，每个样品至少要测定3个以上不同浓度溶液的相对粘度，这是非常繁琐的，而且需时较长，尤其在所得样品量极少的情况下，就难以用此法求得高聚物溶液的，为此，人们找到了更快速的近似方法，即"一点法"。

The conversion rate of the polymerization and the relative molecular weight of the roduct are determined by weight method and Ubbelodhe viscosimeter respectively.

分别用称重法和乌氏粘度计测定了反应的转化率和产物的相对分子质量。
