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 O〓 molecule adsorption process and the surface passivation oxide formation. Thus the mechanical properties and shape memory effect would not change after NiTi alloy surface oxidation. Stable microstructure demonstrates reliability of implant material.

進(jìn)一步對鈦與氧之間相互作用本質(zhì)的研究表明，O 2p軌道和Ti 4s軌道以及O 2p軌道和Ti 3d 4s 4p雜化軌道間的相互作用是NiTi合金表面氧分子吸附的驅(qū)動力婷婷五月丁香四房，在此過程中guochanav，NiTi合金的體相結(jié)構(gòu)沒有發(fā)生變化，從而保證了其一系列力學(xué)性能和形狀記憶特性在表面氧化后不發(fā)生明顯的變化亚洲美女4p变态网站，使表面改性的工作可以安全在线日、可靠的完成而不影響其植入人體后發(fā)揮正常的生理功能。

Based on wide investigations into the dome-shape arch of the material in various linear hoppers and the ways to eliminate the doming, this article analyses the mechanical properties of bulk material flow and points out that the resistance concentration is the basic factor causing the doming.
