英语语法分析

It will then go on to react with the urethane links to form a structure known as an allophanate (see Reaction 4.13).

然后，它会继续发生反应，形成聚氨酯链接称为脲的结构(见反应4.13)。

The presence of allophanate crosslinks can be proved by the highest molecular weight of 20 series copolymers, followed by 40 (in Table 2).

脲基甲酸酯交联键可以从20系列的共聚物的分子量最高，其次是40系列的分子量而得到证实。
