Proceeding from the principles of hydromechanics and gravity separation, the author of this paper has established a differential equation describing the motion of ideal, column shaped particles in a hydrocyclone under low pressure. Based on this equation of the movement of asbestos fibre bundles is set up.Correction coefficients C_R and C_S, representing the effects of resistance caused by different shapes and forces acting on the particle surface respectively, are introduced into this model, thus this equation can be used for studying the movement of particles in any shape in a hydrocyclonc under low pressure.A FORTRAN program for this model has been worked out and has been run on FELIX C-512 computer. The results show that the axial displacement of asbestos fibre bundles determined by computer are generally in accordance with thoseby moviephotographical analysis.

This paper discusses the behavior of traffic jams with catastrophe theory. In highways, the determination of the specific condition of traffic jams-such as critical density and volumn of traffic flow, critical velocity of cars, etc(?)has been a subject in traffic engineering until now. In this paper, the critical value and the fundamantal equation of traffic jams are discussed and studied, and with an exsample the author defines that catastrophe theory is more close to the objective reality than smooth change...
