The expressions of the molecular weight distribution function and the average degreesofpolymerization have been derived, and four special cases were discussed.
求得了分子量分布函数和平均聚合度的解析表达式,并讨论了四种特殊情况。

Pectic oligosaccharide produced by microwave and autoclave extraction were observed with higher degreesofpolymerization than those by an ultrafiltration membrane enzyme reactor.
用微波和高压提取的方法提取的果胶低聚糖比用超滤膜酶反应器的提取的具有更高的聚合度。
