For the trip continually of pulverized coal feeder during operation,through noting,statistic;and analysis on trip phenomena,it is found that the main cause is bad coal,the efficient causes is short acceleration time setting of transducer.

The analytical solution and the numerical one of the acceleration time and the acceleration length are given for particles under the action of Klyachko and Putnam forces.

Based on Arrhenius relationship,the linearized relationship between life and tempera- ture is derived,and the meaning of activation energy and B parameter,and the acceleration factor are discussed.

To the point set obeying even distributing,which lie in the most problem,using an acceleration factor to optimize the method,it can work even better and the runtime reaches O(n).

Based on Arrhenius Relationship, the relation between linearization life and temperature is extrapolated, the meanings of activation energy, B parameter and acceleration factor are discussed.

In order to control the global and local search of particle swarm optimization(PSO)efficiently,this paper mainly analyzed the effect of acceleration coefficients in PSO and pointed out that dissymmetrical and arc cosine method could effectively enhance the performance of PSO.

This paper mainly analyses the effect of linearly varying acceleration coefficients in Particle Swarm Optimization(PSO)and presents a recommended setting of acceleration coefficients.

Based on the condition of constant distribution and const logarithmic standard deviation for Lognormal distribution, the Bayes method is used to analyse the accelerated factor of accelerated life test.

By adjusting the scaling factor and the accelerated factor,generalized projective synchronization between the fifth-order hyperchaotic circuit system and the hyperchaotic systems,chaotic systems and periodic signal can be rapidly realised,and the fifth-order circuit\'s hyperchaotic circuit system can also be driven to arbitrary periodic orbits or fixed point rapidly.
