The major content of the thesis is to simulate the mechanical interaction between two contacting fibers according to the experimental results obtained by petrich and koch . the initial model does n ' t accord with the experimental results well without an additional drag incorporated into it 本论文的主要内容是根据petrich和koch实验观察到的结果，对两纤维直接接触相互作用的过程建立了数学模型，增加了一个与速度相关的阻力，并对这个附加阻力进行了详细阐述。
