Secondly, the operating principle and the mathematical model and the control method about the three-level voltage source high power factor PWM converter are analysed .The generation of the PWM trigging pulse control signal are introduced emphatically. On the basis of this, the hardware experimentation circuits are built with DSP and CPLD, and the trigging pulse signal is generated exactly. The feasibility of the circuit is verified by the experiment result.

其次，分析了三相电压型变流器的原理、模型、控制方法并着重研究其PWM 触发脉冲控制信号发生技术，并以DSP、CPLD 等芯片搭接了硬件试验电路，产生了正确地触发脉冲信号，试验结果证明了设计的合理性。

Improving vertical resolution for density curves is by means of restructuring the response from large and small spacing sondes and borehole effect correction factor and coherence factor are used. Form the principle of GR logging, calculate volumes in investigating areas taken by borehole, formation, up and low shoulder beds, along with distance between center of gravity of the four unit bodies and detector. Based on the above, the weighting function of each unit body to GR signal contributions are established, thus realizing processing of GR logs with high resolution. The resistivity logging model uses "resolution matching" method to improve the resolution of the logs. After the process, PNN model is made to recognize the oil-gas-water bed. Compared with BPNN, the net work is featured swiftness, accuracy and ease of practical application.

Firstly, This text has described information fusion technology characteristic, form structure and concrete processing method, and application of information fusion in fault diagnosis proves the feasibility and validity from the angle of information theory. Based on this,it is combined the fault diagnosis of aeroengine with Information fusion, a method and model which the fault diagnosis of aeroengine information fusion is brought forward. a research which combined neural networks with D-S evidence is brought forward. Based on the analysis of single neural network characteristic, the model of roted neural network is put forward. With the simulation based on the example, we can know evidence theory fusion improved the fault diagnosis It is hard to give the basic probability function in the process of using the evidence theory, So the model based on network and D-S evidence is put forword.
