A new closed loop flow controlling principle through correcting the valve'sopening area while load pressure is changing is carried out. Further more a principle using only oneproportional valve to compound control pressure and flow is suggested. By using very simpleproportional throttle valve in structure, the functions that five kinds of proportional valves orany two of them combined possess can be complimented. After analyzing, comparing, and testing thedynamic and static characteristics of valve with different controlling principles and main valvestructure styles, the optimized structure styles and control methods are achieved.

Based on the unbounded matrix, a void growth model is proposed inthis paper. In this mod- el, extending the Griffith criterion ofenergy conservation during the expanding of cracks to the case ofimpact loading, we propose an assumption that the strain energy inmatrix can transform into its surface energy and kinetic energyduring the micro-void growth. The void growth velocities of the OFHCcopper and LY12 alu- minim are calculated, and the result of whichagrees with that of Seaman

According to advantages of neural network and characteristics of operatingprocedures of engine, a new strategy is represented on the control of fuel injection and ignitiontiming of gasoline engine based on improved BP network algorithm. The optimum ignition advance angleand fuel injection pulse band of engine under different speed and load are tested for the samplestraining network, focusing on the study of the design method and procedure of BP neural network inengine injection and ignition control. The results show that artificial neural network technique canmeet the requirement of engine injection and ignition control. The method is feasible for improvingpower performance, economy and emission performances of gasoline engine.

This paper briefly presents characteristics, application and development of the metallic foams. Sound specimen has been achieved with prepared foam aluminum by using investment casting process. The preparation of plaster prefabricated mould is one key in investment casting. Main composition, ingredient and affecting factors of plaster mould are also discussed and the vacuum-infiltrated shaping technique is found to be another important link. The penetration model and the affecting mechanism of the main parameters are also analyzed. As a result, the optimum values are determined.

The coal-rock interface recognition method based on multi-sensor data fusiontechnique is put forward because of the localization of single type sensor recognition method. Themeasuring theory based on multi-sensor data fusion technique is analyzed, and hereby the testplatform of recognition system is manufactured. The advantage of data fusion with the fuzzy neuralnetwork (FNN) technique has been probed. The two-level FNN is constructed and data fusion is carriedout. The experiments show that in various conditions the method can always acquire a much higherrecognition rate than normal ones.

The density of the SLM forming parts is investigated to determine the good technological parameters of SLM at the same time obtain the dense parts. In the SLM experiment, material used is Fe-Ni metal powder, the good technological parameters of SLM are determined by analyzing the effect of the laser electric current, the laser pulse width, the pulse of laser light frequency, the scan speed, the scan interval, push powder thickness and the scanning way on the single channel scanning, the single-layer scanning, which can lay the foundation for afterward block body formation. Microstructure and properties of the block specimen prepared under the different SLM process parameter are studied by the density measurement and the scanning electronic microscope analysis. The forming parts with high density have been prepared under the optimal SLM process parameters.
