The techniques of using S-wave response to investigate fractured anisotropy medium have achieved good results in practical application. However, these techniques are very complex and expensive, and then limited their application. Whenas various P-wave attributes are effectively preserved by accurate P-wave acquisition and processing techniques, thus it creates a beneficial condition to detect fracture using P-wave data.

利用横波响应进行裂缝性各向异性介质的检测在实际应用中取得了很好的效果，但技术复杂、成本较高使该方法的广泛使用受到限制，而纵波资料采集和处理技术的精细有效保持了纵波的各种属性，这为直接利用纵波资料进行裂缝检测创造了条件。

Simultaneity, the adsorption energies of single Si adatom on the H-terminated Si (100) surfaces are specially mapped out in this paper, from which the favorite binding sites and possible diffusion pathways have been achieved. The variety of the diffusion anisotropy with the coverage transforming is obtained. The energy barriers of the adatom diffusion are found to be higher than that on the clean surface, because the H atoms saturate the dangling bonds of the surface Si atoms.

同时，本文研究了附加硅原子在理想H-terminated Si(100)表面的沉积扩散行为，计算得到了一系列沉积点和可能的扩散路径；讨论分析了扩散行为的各向异性以及氢覆盖率对各向异性影响的规律，并且发现附加硅原子在H-terminated Si(100)表面上的扩散势垒比在清洁Si(100)表面上的高，我们认为这主要是因为氢原子饱和了表面上硅原子的悬挂键，提高了扩散势垒。
