Occurrence Situation of Rice Blast and Its Control Countermeasure in Daozhen County of Guizhou;

Sedimentary facies characteristics of the Datang bauxite deposit in Daozhen County,Guizhou;

Vacuum pipe waste collection system equipment,principle and application status at home and abroad were introduced,suggestion of popularizing and application in China was put forward.

Fast evaluating methods on guidance instrument error based on experiment design and trajectory simulation;

Trajectory simulation and analysis for laser propulsion launching microsat;

Modeling and trajectory simulation of guided bomb based on GPS/SINS;

Many kinds of channel simulation models are based on Rayleigh fading channel simulation.

The research of fading channel simulation in complex communication environment is of vital importance to the study of space-time signal processing technologies.

The wireless communication channel is difficult to test in practice, and this problem can be solved by channel simulation.

Study on numerical calculation method of ballistic simulation

Through classification and analysis of the factors, which affect the point of fall accuracy of the ballistic missile, the method is raised to forecast and modify the windage of point of fall by using simulation technology and to design and analyze entire ballistic simulation experiments with total factors to get some advices to develop the missile.

The ballistic simulation model of vertical launch missile was established by using quaternion method,and the effect on the ballistic distribution caused by different reasons was analyzed through the model.
