The three-phase voltage type SPWM inverter output voltage and current harmonic and its generation rule is discussed. And put forward a new easy to implement harmonic suppression strategy, the method through the correct choice of the carrier frequency and the sinusoidal wave superimposed on a three wave makes saddle shaped wave, to produce a corresponding SPWM waveform control inverter switch on-off thus improving the output waveform. Mathematical analysis shows that is helpful to reduce the output voltage THD ( waveform distortion factor ), improved harmonic current loss and torque characteristics, the simulation results prove the validity of these measures and practical.

According to problems of deficiency guidance in the traditional virtual disassembly training, the planning method of disassembly operation process based on Petri-net is presented. By this method, Disassembly Petri-Net (DPN) model process-oriented is built. In this model, constraint relations for the process and generation rule for DPN are studied. At last, by taking the transmission of bulldozer as example, planning method and its solution aimed at timeliness are proposed. The example shows that the planning results can improve training effect significantly, which provides a practical and efficient training platform for trainees.

During lignite pyrolysis process, there will produce large amounts of gas which is low calorific value, combustion difficult. This paper creatively put forward a program: high temperature and oxygen-containing flue gas of coal-fired mix combustion with low calorific value gas. Compared to mixing high calorific value fuel, the distinguishing feature of this program is ultra-low cost, and technically feasible. In this scheme, the stability of high-temperature and oxygen-containing flue gas is key technology. Through coal-fired experiments, we obtained generation rule of high-temperature and oxygen-containing flue gas, and summed up a diminishing marginal effect.
