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

A dynamic analysis approcach to investigate the state of load distribution among contact bearings of double circular are belical gears is proposed and a computer program is developed for calculating the factor of iced distribution based on the theory of W-N gears. The changing situations of load distribution among contact bearings of the gears influenced by main issues are analyzed by a series of parametric studies.

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.

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.

C60 is successfully solubilized in micelle of six kinds of surfactants and UV/Vis spectra ofC60 in micellar system are studied. It is found that Brij-35 is the most efficient surfactant forsolubilization of C60 and the possible states of C60 existed in surfactants are also *** of surface tension show that the sites for solubilization of C60 not only depend on thesorts of surfactants but also on their structures.
