    研究表明，對于城市活斷層的抗干擾高解析度淺層地震勘探，在數據採集環節應採用具有線性或非線性變頻掃描功能的可控震源和與其相匹配的地震儀器，以及小道間距、小偏移距、多接收道、短排列和高頻檢波器接收的工作方法；在數據處理與解釋環節，要重視折射靜校正技術、噪聲壓制技術、高精度速度分析技術、子波壓縮技術、子波零相位化技術和疊前偏移技術等的應用。
  2. In this chapter, the method of bldcm rotor position detection is first discussed. then the principle and algorithm of bemf zero crossing point detection is explained. in succession, the chapter dissertates the software realization of the bemf zero crossing point detection algorithm, the software disturbance filter and the modification of phase displacement, and the software realization of commutation point

    在這一章中，先簡述了無刷直流電機的轉子位置器檢測方法；然後論述了反電動勢過零檢測原理和演算法以及該演算法的軟體實現、軟體濾波和相移修正、換相點的軟體實現；最後對軟體開環換相起動策略作了詳細論述。
  3. In this thesis, the tradition phase - shift full - bridge zvs dc / dc converter are analyzed, and then a new dc / dc full - bridge converter employing switches clamping in secondary side of transformer is proposed, and the converter employing saturable inductor clamping are studied, and zvs ( zero - voltage - switching ) can be easily achieve by experiment validate

    本文分析了一些傳統的移相全橋軟開關變換器，提出了開關管箝位dc dc全橋變換器拓撲方案，並對飽和電感器箝位dc dc全橋變換器進行了研究，並進行實驗驗證，從而解決了開關管的零電壓開關問題。
  4. Two wedge interferometers are designed that the thickness of one is higher than the other. so when the incident coherent light through the interferometers can acquire two fringe patterns which having space shift, but the incident incoherent light only result in consistent intensity signal. through a differentiating amplifier, two signals subtract which can eliminate noise of background and result in higher contrast ratio fringe signals. this method largely improves the system and the ability of detection. the spacing of line fringes is a function of incident laser wavelength, by analyzing, we can extract the wavelength of incident laser. the optical unit analyzing and results also simulated with matlab

    當背景光入射時，直接穿過干涉儀，僅發生強度的衰減，在兩個探測平面上產生幅度基本一致的灰度信號，通過差分放大器，相消為零，從而抑制了背景干擾。當激光信號入射，穿過干涉儀時受到調制，在探測平面上產生干涉條紋。通過所設計的存在平均厚度差的雙楔形干涉儀，兩路干涉條紋圖案出現相對移位：在兩個探測平面對應的位置上，一路出現亮紋，另一路出現暗紋。
