However,authors still do not find the relevant references on convergence and symmetric problems of the semi-analytical solution.Based on the semi-analytical solution for Hamilton canonical equation theory,the formulations of the clamp and simply supported and symmetric boundary conditions on the Hamiltonian element are derived by the variational principle.Several numerical examples show that with increase of meshes,the convergence rate of the semi-analytical solution is faster than the convergent rate of traditional finite element method based on displacement.
①在厚度上没有任何位移和应力模式的假设,由于传递矩阵方法的引入,从理论上讲,不受板壳厚度或层合板壳层数的限制;②采用弹性力学的Hamilton正则方程半解析法,可以克服边界的局部化效应[8];③由于在平面内或圆柱壳的曲面内采用了有限元法,所以一般的板壳问题不受结构侧面边界条件的限制,在复杂工程板壳问题上具有广泛的应用领域。

AVO analysis is suggested for solving to solve the difficulty in identification of thin alternating layers in exploration of oilfields. It can improve the current method that has no thickness variable in the formula of reflective and is limited by sampling rates in calculation of the coefficient in the time of domain. Using the relationship of stress and displacement on two interfaces, this paper derives the spectrum of reflective coefficient for any incidence angle and thiekness of thim layer based on the equation of seismic wave propagation in the frequency domain.

Because the EPWE method is designed to derive easily the evanescent modes which can be used for the matching boundary conditions, we can get the transmittance for the semi-infinite photonic crystal. In this study, some interesting behaviors can be observed, for example, the transmittance is very sensitive to the surface we chose. The transmittance even can be almost 1 or 0 when the cutting planes of photonic crystal are different for the specific frequency. In this proposal I want to see the reason of the total reflection which seems to be conflicted with the existence of the propagation modes at that frequency and what will be happened when we consider the finite thickness case.
在EPWE 的方面,在这三年的时间里,我会尽量完成有限厚度的光子晶体的计算,因为以前主要算的是半无穷的光子晶体的计算,当中也看到了一些很有趣的行为,比方某些频率下,其穿透率与它的介面有很大的关系,因为,当光子晶体的切面不同,在特定频率下,其穿透率可以由几乎全穿透变成全反射,这里我想看看如果考虑厚度,到底会对系统有什麼影响。
