The results show that whether the stiffness profiles are smoothly varying or layered, the fundamental mode dominates the surface wave field and the effective phase velocity approaches to the phase velocity of the mode in far field for the regular profiles. For the irregular profiles, the higher modes have a significant influence on the surface wave field. The intensity and the frequency range of the influence are related to variation of the profile stiffness.

结果显示，无论剖面刚度是缓变还是分层变化，对规则剖面，表面波场基阶模态占主导地位，远场表面波有效相速度与基阶模态相速度接近；对不规则剖面，表面波场中高阶模态影响较大，影响程度及频率范围与剖面刚度变化有关。

In the face of above cases, this paper attempts to break through the bottleneck of data security with another way. Through study of Error Correction Code and Finite Field theoretics, this paper tries to apply the Reed-Solomom arithmetic based on Finite Field Galois Field to Redundant Array of Independent Disk, and tries to realize a simple RAID6 level programme, thereby could offer an idea for securer storage device.

Then we in-vest gate Seiberg-Witten map, which defines the equivalence relation of the gauge symmetries in different spaces. We also analyse the U gauge electromagnetic field in noncommutative space. Finally we discuss the ambiguities of Seiberg-Witten map, and find although that some part of the ambiguities can be absorbed by gauge transformation and hence negligible, the existence of the matter field makes some other parts difficult to be absorbed by gauge transformation or field redefinition.

然后利用Seiberg-Witten映射，我们研究了不同空间的规范对称性的等价问题，并对非对易空间的电磁场进行了微扰分析，最后我们对Seiberg-Witten映射的松动进行了讨论，研究发现这些松动中的一部分可以由规范变换吸收因而是可以忽略的，由于物质场的存在，另外一部分很难用规范变换和场的重定义吸收。
