Operating principle is introduced of isolated switches production model 500 kV GL of Japanese Mitsubishi Corporation,and the causes of the operating anomaly are analysed,counter-measures are given.

By using mutation and extending searching space, an efficient single loop SAA is improved.

We propose a modified genetic algorithm(GA) without mutation operators in order to reduce computation time and to simplify designing.

Considering that the organisms have the phenomena of escaping from the original cradle when they find the survival density is too high to live, this paper uses a special mutation –escape operator to make particles explore the search space more efficientl.

Two effective crossover and mutation operations based on the structures of chromosome are designed for the genetic algorithm.

Furthermore,a mutation operation is added to the iterative process to initialize the positions and velocities of the unable particles in order to keep the diversity of particle swarm.

Also,a mechanism of generating the initial solutions and two effective crossover operators and mutation operators are designed for the genetic algorithm.

This article first carries on the elaboration of Web service,then analyzes the web service standard,and proposes four kinds of asynchronous operation type based on the Web service.

Taking use of the advantage of asynchronous operation of DS1609 dual port RAM, we can not only simplify the program, but also improve the reliability of the multi-microprocessor system.

The complexity and composition of Web services make Web services working in an asynchronous operation style and substituting RPC operation style gradually as a leading operation style.
