The result shows that with the addition of rare earth elements, ultrasonic irradiation and magnetic field, the chemical component, surface configuration, microstructure and properties of electroless co - ni - b and co - fe - b alloy changes remarkably. such kind of change can be described as the followings. firstly the depositing speed of electroless alloy bath is raised while the polarizability and cathodic overpotential are reduced ; secondly the surface quality of the alloy coating and adhesion of the coating and matrix are improved ; thirdly in the coatings the content of the elements in the transient group increases, but the content of cobalt decreased ; fourthly the amorphous structure is transformed to microcrystal structure and polycrystal structure ; fifthly the microhardness and wear resistance of the coating are enhanced ; sixthly coercitive force is reduced, and magnetoconductivity of the coating is increased ; lastly the magnetic intensity of the coating increases with the addition of energy and light rare earth elements such as ce, la and decreases with the addition of heavy rare earth elements such as y. on the other side, when the alloy coatings passes through the heat treatment under the temperature of 250 or 500, their properties will change

This thesis chooses b spline wavelet that adapts to the analysis of power system signal, and uses the wavelet transformer to analyze the magnetizing inrush current and inner fault current. a transformer microcomputer protection was designed in this thesis, and in the base of intermission angle principle, a new criterion was established, which pierces through the traditional method with accurate measurement of intermission angle, but analyses the wave by wavelet transform. this criterion is lower in hardware, so it will be realized in the existing hardware

Taking the hvdc systems as a variable admittance connected at the inverter or rectifier ac bus, the analytical description of the relationship between the variable admittance and active power flows of each generator can be derived. the traditional generator dynamic equations can thus be expressed with the variable admittance of hvdc systems as an additional state variable and changed to an affine form, which is suitable for the global linearization method being used to determine its control variables
該方法基於微分幾何理論,將直流輸電系統等效為兩個分別連接在整流側和逆變側的變導納支路;在推導出直流輸電系統的等效變導納與各發電機輸出電磁功率間的解析關系后,傳統的發電機動態方程可被表示成仿射非線性的形式,因而可應用全局線性化方法來求得直流輸電系統的調制量。
