The structure of ejector used in automotive power steering oil discharge equipment is designed in accordance with the theory of gas-liquid ejector.The two important parameters of the ejector are elected respectively to five values and then 25 ejector models are obtained by the permutations and combinations.The ejector's CFD model is created by Fluent module of Ansys then it is divided into a grid and analyzed. Analyse its pressure distribution and velocity vector which provides the optimal size for the manufacture of the ejectors and a theoretical basis for experiment.

The high capability of O-E theodolite to track and acquire fast moving targets is required these years because of the rapid advancement of tested targets and automation of equipments. The traditional method of increasing the frequency width is limit. By using multi control models and velocity leading the capability to track and acquire fast moving target is improved highly. The theories and technologies discussed in this dissertation were tested with experiments. It verifies that the theoretical analysis in this dissertation is correct.

Missile's attitude change will be delivered to visual axis through stabilized platform during maneuvering flight and the missile vibration will be an interference source to visual axis stabilization. In order to solve this problem the coupling relationship between missile attitude and visual axis is obtained by Coordinate transformation. When the seeker stably tracks a target the angular velocity of visual axis in inertial space is zero so the relative angular velocity of roll axis and pitch axis can be derived for servo control. According to Oura dynamics equation the dynamic models of roll axis and pitch axis were established and kinetic equations of two axises were obtained. The dynamic models can provide theoretical basis to developing research of servo control system and structural optimization design of stabilized platform. Finally some measures could reduce the dynamic coupling between the framework was given. 2011 IEEE.

In order to put the parallel one-way hash function into engineering two designing models based on pipeline technology are proposed in this paper. The definition of one-way hash function is shown first and the structure and limitation of the current hash functions are discussed afterward. By analyzing the difference between parallel computation on different platforms and classifying one-way hash functions on application basis the possibility and method of parallel one-way hash function designing on different hardware platforms are described two designing models are constructed for the parallel one-way hash function designing. Finally some attentions for designing are proposed from the engineering angle. The pipeline models that proposed in this paper contact the theoretical rationality and the engineering application of parallel one-way hash function together which can improve the practicality of parallel one-way hash function to a great extent. 2010 IEEE.

This paper advances a method to develop simulation system which is based on VC++ 6.0 and MultiGen Vega and takes the mathematical model of Photoelectric theodolite and target as the theoretical basis. We modeling the simulation system by MultiGen Creator and then drive the simulation models through MultiGen Vega program under the circumstance of VC++6.0 simulate the work situation of theodolite to track the Air target achieve the development of simulation program. Finally analyze the results of simulation and compare it with the Actual data which is very important for the research of the real system. 2010 IEEE.

The electron transport behavior of polymer-derived amorphous silicon oxycarbonitride ceramics is studied by measuring their temperature-dependent electrical conductivities. The experimental results are analyzed using theoretical models. The results reveal that the materials exhibit three conduction mechanisms: conduction in extended states conduction in band tails and conduction in localized states. Particularly it is found that in a low-temperature regime the conduction of the materials follows a band tail hopping mechanism rather than the previously assumed variable range hopping mechanism. The results also reveal that energy gaps such as EC-E F and EC-EA decrease with increasing pyrolysis temperature. 2009 The American Ceramic Society.
