Based on a large number of dynamic shear tests, several mechanical models of dynamic shear test of bulk materials have been established in this paper.

A Brief Remark on the Interrelation between Molecular Static State and Dynamic State in Organic Chemistry;

The emphasis has been put on the method of controlling silk longth by using high speed register of PLC under the dynamic state.

In order to solve the convergence problem and overcome the difficulties for setting the initial values in the steady state simulation of distillation columns, a combined steady-dynamic state model is proposed by taking the advantage of the distinguishing feature of the implicit integration.
