Based on predecessors'work, and the plant data of total conversion rate and number-averaged molecular mass, the Cauchy distribution of micro cores is proposed in terms of the principle of probability and statistics. The macro kinetic model with expressions of the total conversion rate and number-average molecule mass is derived from the macro mixed method.

在总结分析前人成果的基础上，利用生产现场采集的转化率与平均分子量的人工分析值，基于概率统计原理提出了丙烯腈连续水相聚合过程中聚合体微团转化速率的Cauchy分布，并由此用宏观混合法导出了由总转化率和平均分子量的表达式组成的动力学模型。

If necessary, nylon, acrylic and polyester fibers may be bleached with sodium chlorite under acidic conditions.

在必要时，尼龙、丙烯腈、涤纶纤维可在酸性条件下用氯化钠漂白。

We analysed precursor solidification mechanism,pointing out that solidification mechanism is crystallization,congelation and glass transition.

文章分析了纤维的固化机理，指出固化机理有三个：冻胶、结晶和玻璃化转变，其中蕴晶结构对聚丙烯腈基碳纤维原丝结构有重要影响。
