    摘要本文從時間域、頻率域、三維空間域介紹了礦山工程裂隙破碎帶主要的地震運動學、動力學屬性參數，包括相對振幅、波峰相位時間、相似系數、主頻帶能量、二維空間時間梯度和相干系數等，提出了礦山工程裂隙破碎帶三維地震屬性的去噪平滑、歸一化、相關分析、特徵變換的處理方法以及裂隙破碎帶的模式識別原理與方法，並用實例說明了該方法的應用效果。
  2. Abstract : we conduct a theoretical study on the properties of a bound polaron in a quantum well under an electric field using linear combination operator and unitary transformation methods, which are valid in the whole range of electron - lo phonon coupling. the changing relations between the ground - state energy of the bound polaron in the quantum well and the coulomb bound potential, the electric field strength, and the well width are derived. the numerical results show that the ground - state energy increases with the increase of the electric field strength and the coulomb bound potential and decreases as the well width increases

    文摘:採用線性組合算符及幺正變換方法研究了電場對量子阱弱耦合束縛極化子的性質的影響.推導出量子阱中束縛極化子的基態能量和庫侖束縛勢、電場和阱寬的變化關系.數值計算結果表明，基態能量因電場和庫侖束縛勢的不同而不同，隨電場和庫侖束縛勢的增大而增大，隨阱寬的增大而迅速減小
  3. Based on signal from carbon fiber composite defects such as lamination, hole, looseners in ultrasonic testing, this paper performs wavelet packet transform on the ultrasonic signals to extract statistics of approximation coefficients and detail coefficients that contain a great part of signal energy as sample - features
