Preferential oxidation of Ti on NiTi alloy surface has been observed and was consistent with the experimental result and the free energy of formation A G?(298K) of NiO, TiO, TiO2. Mulliken population and the partial density of state analysis showed that the interaction between Ti and O atoms was mainly donated by O 2p and Ti 4s orbital and O 2p and Ti 3d, 4s, 4p hybridization orbital. The electron structure in NiTi bulk material was not altered during 62 molecule adsorption process and the surface passivation oxide formation.

进一步对钛与氧之间相互作用本质的研究表明，O 2p轨道和Ti 4s轨道以及O 2p轨道和Ti 3d 4s 4p杂化轨道间的相互作用是NiTi合金表面氧分子吸附的驱动力，在此过程中，NiTi合金的体相结构没有发生变化，从而保证了其一系列力学性能和形状记忆特性在表面氧化后不发生明显的变化，使表面改性的工作可以安全、可靠的完成而不影响其植入人体后发挥正常的生理功能。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

Conditions of the seepage and stress is a dynamic process, and also shows its interaction and interdependence. Owing to the closure of the fracture, the hydraulic gradient and the permeability pressure of the fracture turn large, and also promote the expansion of water cracks, and fissures connectivity increasing. The increase of the crack opening width will result in the increase of the infiltration capacity and seepage flow, and the reduction of seepage pressure. Because of the dynamic dependence of the fracture aperture, pressure and seepage, under certain conditions, changes in fracture aperture can lead to the formation of local water-passage, and the local emission of high pressure water, and thus promotes the formation of the sudden outgush disasters.

结果表明：洞室开挖完成后，在围岩渗流与应力耦合作用下，围岩中裂隙隙宽、裂隙中水压及其渗透流量的变化是一个动态过程，且相互作用与相互依赖；裂隙的闭合使得结构面水力梯度变大，作用在裂缝上的渗透压力增大，促进导水裂缝扩展，裂隙连通性增加；裂缝张开度增大，渗透能力增强，渗流量增大，其渗流压力相应降低；由于围岩中裂隙隙宽、压力和渗流量的动态依赖性，在一定条件下，裂隙隙宽的改变可导致局部水力通道的形成，高压水头从局部涌出，从而促进突水灾害的形成。
