  1. The dissertation is organized as follow : first, the characteristics of srm and its control system ' s development are introduced. previously major methods used to implement non - position sensor detection and the significance of making search for this direction is generated. and the configuration and fundamental operating principle of srm are analyzed ; some study of linear model and nonlinear model with phase coil as fundamental parameter are presented and sr ' s linear model and nonlinear model are set up

    本文就以上兩個問題進行了深入研究，首先介紹了sr電機及其控制系統的發展歷程，研究無位置傳感器srd的意義和總結已有的無位置傳感器檢測方法，並且通過分析sr電機的結構和運行原理，研究sr電機繞組的線性電感模型和非線性電感模型，建立了電機的線性和非線性數學模型，重點研究sr電機的非線性模型，為sr電機運行與控制特性的研究和模擬研究奠定了理論基礎。
  2. The characteristics of damping shows that the uncompensated parallel ac transmission line can release the coupling between the hvdc and generator and improve the damping of the system, hence the possibility of subsynchronous oscillation decrease. in such a system scheme, the hvdc system dominates the changes of damping due to the small magnitude of the damping provided by ac line. when the ac transmission line is compensated with a fixed series capacitor, the situation will be totally different

    其中，並列運行的無串補交流輸電線路可以緩解hvdc與其臨近機組之間的機電耦合程度，改善hvdc的電氣負阻尼特性，從浙江大學博士學位論文摘要而減輕機組發生次同步振蕩的危險性，此時系統的整體電氣阻尼特性由hvdc的性質決定;但若交流線路中存在串聯補償電容，則系統幅值較大的電氣負阻尼不僅可能使整流站機組發生次同步振蕩，逆變站附近機組同樣存在發生次同步振蕩的可能性，此時系統的整體阻尼特性由串聯補償電容的性質決定。
  3. The software adopts three kind of control mode to start up the data acquisition system, it ensures reliability of the acquisition system. the control system communicates with the shipborne support system adopting broadcast when down and timing when up, and requires return for the remote instructions, so it ensures the communications of the five bouys with the control and acoustic emission vessel. this software is based on assemble language of mcs51, it is held in the eprom in mcu

    控制和通信軟體採用設定採集時間表、外推採集與啟動採集三種方式控制採集系統，可靠地保證了遠程、無人值守浮標在長時間、連續工作情況下數據採集的很高的可靠性；控制和通信軟體採用下行廣播、上行時分的工作哈爾濱工程大學碩士學位論文方式實現各浮標與船載分系統間的通信，且無線電遙控指令執行反饋，可靠地保證了浮標與船載分系統間的通信。
  4. Abstract : burrowing behaviors of the plateau zoko rs ( myospalax bailely ) in rel ation to soil hardness were investigated by using radio - telemetry at haibei alp i ne meadow ecosystem research station, qinghai, china

  5. The solving steps are as follows : the field is divided into three regions by the cylindrical surface of the finite - length cylinder and the location of the delta - coils. because " the surface current source is placed at the interface, the non - homogenous restricted equation on the magnetic vector potential is transformed into the homogenous helmholtz equation. by using the method of separation of variables to solve equation and according to the interface conditions and the condition at infinity to determine the unknown constants, the expressions for the magnetic vector potential of the three regions are solved out

    在求解過程中，假定放置式圓柱線圈是由無窮多個對稱圓環線圈密饒而成，首先求解含有有限長磁芯的通電對稱圓環線圈的電磁場：以有限長圓柱磁芯的側面和圓環線圈所在圓柱面為分界面將場域劃分為三個小區域，由於場源放置在內邊界面上，使得關于矢量磁位的非齊次約束方程轉化成齊次亥姆霍茲方程，利用分離變量法求解，根據分界面鄭州大學碩十研究生畢業論文摘要條件以及無限遠條件確定待定常數，從而得到各場區矢量磁位的表達式。
