Due to nonlinear bottom boundary condition, the generation of internal tides over finite topography can only be deal with by using of ray - tracing method beforetime. the transforms introduced in this dissertation make it possible use eigenvalue method to investigate the generation of internal tides over finite topographies
由於非線性邊界條件的使用，前人處理有限地形上內潮的產生問題只能求助於射線理論，本文提出的坐標變換將若干海底地形變換成平底，從而使得利用特徵值方法研究這些地形上的內潮生成問題成為可能。 -
The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells, involving the effect of transverse shear and rotational inertia, are derived. by applying the reverberation method, the displacement and the resultant forces of the shell in the phase space are expressed. then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms. furthermore, the transient solutions are decomposed to the generalized ray integrals and computed numerically
分析了計及剪切變形和轉動慣性的有限長正交異性圓柱殼中彈性瞬態波的傳播問題，採用回傳矩陣法，在相空間中給出了位移和內力的表達式。再利用laplace逆變換，得到正交異性圓柱殼受軸對稱沖擊作用時彈性瞬態波解，然後將其分解為若干廣義射線積分之和，並用數值方法求解之。 -
Based on the analyzing of the dss ' s basic theory of tomography, an inversion scheme that can be described as the combination of the finite - difference inversion and ray inversion using traveltime, amplitude and gravity data is proposed
在分析深地震測深剖面層析成像基本理論的基礎上提出了利用走時、振幅和重力數據，通過有限差分反演和射線反演方法對地殼上地幔結構進行層析成像的研究思路。 -
These methods can be divided into two types. one is the methods based on the ray - tracing technique, such as monte - carlo method, zone method, discrete transfer method ; the other is methods based on the discretization of radiative transfer equation, such as discrete ordinate method, finite volume method, finite element method and so on
目前輻射傳遞問題的求解方法可分為兩類，一類是以射線蹤跡為基礎的方法，如蒙特卡洛法、離散傳遞法、區域法等;另一類是基於輻射傳遞方程離散的方法，如離散坐標法、有限體積法、有限單元法等。
