摘　　要：在定粒缫丝工程中采用粗细茧丝搭配的方法进行配茧缫丝时,需要根据落绪茧及茧丝粗细搭配状况选择适当的接绪茧接绪,以保持厚薄茧型的搭配,减小生丝纤度方差.本文对该缫丝动态过程进行数学建模,给出差微分方程组及其平衡状态下不同茧层茧粒数的分布.通过对定粒缫丝动态过程的计算机模拟,对获得的理论结果及其在缫丝工程管理中的应用问题进行了讨论.Matching thick cocoons with thin cocoons is often used during the reeling process with fixed number of cocoons. In order to keep the satisfied size and minimize the size deviation of raw silks. right cocoons are added according to the dropped cocoons and the cocoon number of different layers. By modeling the reeling dynamic process. the paper gave the system of differential-difference equations and derived the distribution of cocoon number of different cocoon layers in the balanced condition. By simulating this process on computer, the paper discussed the theoretical resutls and its＇ application in controlling reeling process.
