  3. To investigate the influence of transmission attenuation of seismic waves in a layer - cake model, the authors formulated a seismic convolution model by considering the coefficient of transmission attenuation, and then provided a new forward algorithm for the model - based seismic inversion of impedance

    摘要研究了地震波在層狀地質模型內透射衰減對地震反射信號振幅的影響，給出了含透射衰減的褶積模型，為基於模型的波阻抗反演提供了一種新的正演方法。
  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。
  5. This paper particularly focuses on the theory and implementation of how to inverse underground structure by comparing incident wave and scattering wave, and recording the spare time of the waves, and forward calculations for igneous, metamorphic and sedimentary rocks are carried out to verify the feasibility
