    本文對多柔盤轉子-支承系統的振動現象做了以下初步探索：用質量離散化方法把原轉子系統簡化；採用matlab語言編制了對傳遞矩陣法計算多柔盤轉子-支承系統的臨界轉速；用matlab語言對riccati傳遞矩陣法和有限元法編制了程序計算系統的不平衡響應；並針對其過臨界轉速時振動較大的現象，提出採用變間隙控制油膜剛度和阻尼，從而使原系統的在特定轉速（臨界轉速）的一段范圍內不平衡響應減小；並從被動控制與主動控制兩方面進行數值模擬，取的了較好的控制效果。
  2. Based on the resolving algorithm of continuous - layer method, the time order analyzing curves, acceleration curves and the response spectra of transfer function at the different points of the ground and at the same point on the different ground conditions are gained. it demonstrates that the responses of ground in x, y and z axial directions all change by time, and the obvious wave propagation appears in ground. for different observing points on the same ground condition, at more distant points from the load line, the less swings are found, that is to say, vibration possesses the obvious characteristic of attenuation

    基於分層法的解析演算法，得到了在不同點以及在同一點但不同地質條件下的時程分析曲線、加速度變化曲線和傳遞函數反應譜，結果表明，地基土在x 、 y 、 z三個方向的響應都是隨時間變化的，並且伴隨有明顯的波動現象產生；對于相同地質條件的不同觀察點，距離荷載作用線越遠的地方振幅越小，即振動具有明顯的衰減性。
  3. To solve this problem, quick range measurement technology was researched based on the method of propagation delay and working principle of cpld. a time measurement circuit with an accuracy of ? 0. 2m was designed and accomplished. it could finish the whole measurement process in 80ns after the bounced pulse was received

    針對該問題，基於傳遞延時插入法和cpld的工作原理，對快速測距技術進行了研究，研製了一種能實現收到回波脈沖后80ns內完成測距，測距精度0 . 2m的計時電路，並將該電路集成於一片可編程邏輯器件中，減小了電路面積和功耗，增強了抗干擾能力。
  4. The recursive criterion of transient current protection based on mallat wavelet transform is presented in order to meet the real - time demands. the reserch shows deficiency existed in the prevenient principle of transient current protection, so a new improved scheme of transient current protection is proposed. the characteristics of transient protection at different bus distribution capacitance is also analysed in this thesis. the study shows that operate of transient protection is correct when the bus distribution capacitance change. other conclusion include : the trip of transient protection must be locked when the power circuit breaker of transimission line operated, because the trip is incorrect at this time ; the features of transient current and it ' s energy is different between the fault and thunder over - voltage in transimission line, and them can be identified ; the ratio of high frequency component of current in serise capaciters compensation line, svc and hvdc system is far little than fault transient current, so all of them do not affect the working of trasient current protection

    應用功率譜估計方法討論了故障高頻暫態噪聲信號在頻率軸上的分佈情況，利用功率譜分析結果實現的非參數化系統辨識方法研究了母線分佈電容對電流高頻暫態信號的衰減特性。論文的後半部分（第五，六，七章）著重分析了現有基於故障電流的暫態保護原理和判據存在的問題，提出了新的實現方案，並討論了暫態電流保護的運行性能。利用多分辨分析和小波分解快速演算法構成的遞推暫態保護判據，可以準確區分故障線路和非故障線路，實現超高速暫態電流保護，計算更為簡單方便，計算速度更快。
