With the analysis of the principle of calculating floating head flange and the calculation chart based on the numerical solution, the possible 'optimum design and most economical design were determined.

This paperstudies optimum design conditioned equations of four-stage raw material gas quenchedcatalytic reactor and describes optimum design conditioned equations of this reactor.

On the basis of the analysis as above,the consummate osillation condition is given in the first place,and the optimum design to the oscillator is also obtained.

Dynamic Simulation and Optimal Design Analysis for Diesel Engine Governing System;

First of all, the equation of shrunk interface pressure and the condition of diametrical ratio are deduced under the optimal design principle of shrunk double-layers cylinder.

Based on the equation of shrunk interface pressure and the condition of diametrical ratio under the optimal design principle of shrunk-on cylinder, it is found that the diametrical ratio isn t true of the optimal design principle and the distribution of stress isn t very equality through analyzing and calculating the diametrical ratio and stress to a super high pressure cylinder.

n this paper EPDM microwave vulcanization system consisted mainly of microwave vulcanization behaviors,effect factors,microwave heating equipment and optimum compounding technique　atc.
