The proper analysis of the mixed queuing system is given.

Among these model,the queue modle of multil-windows and mixed system is better than others.

A knowledge based hybrid control system for plate rolling process;

Design method study of hybrid control of passive tuned mass damper in combination with viscoelastic damper based on model of recurrent neural network with bias unit;

Structural hybrid control with MRD and sliding base-isolation under bi-directional earthquakes;

A new mixed control strategy for induction motor drives;

Nonlinear mixed control for silicon contents of hot metal in BF ironmaking processes;

A mixed control pattern is introduced that logical control with motional coordinate control is combined in single chip microcomputer control system.

This paper discusses on the method for measuring the content of the effective components in the mixed preparation of Procymibone and Chlorothanil under the same gas chromatographic condition, and points out that the method is simple, quick and accurate, and the variation coefficient of Procymibone and Chlorothanil is 2.

In combination with the process characteristics of Stainless Steel Branch's 1780mm hot rolling mill,the stainless steel and carbon steel mixed rolling was adopted to improve stainless steel's surface quality and productivity.
