The sulphur atom in the intermediate has sp2 hybridization, and the remaining p orbital is symmetrical to the d orbital of the metal center. Thus, the lone pair on the p orbital can have interaction with the d orbital to form a π bond, which leads to the coplanarity of the center of Cp ring, Ru, P, S and Si atoms, rather than the deviation of P, S and Si atoms from the plane.

It is found that the nature of the interaction between CO and Pd(110) surface by population analysis and DOS analysis what the 5σ orbital of CO and the d orbital of metal formed electron donation; and the 2π* orbital of CO and 4s and 3d orbital of metal formed electron back- donation.

The results show that the sturcture of each of Tin clusters is obtained by capping one Ti atom to the Tin-1. The Natural bond orbital analysis show that the 4s , 4p, 4d orbitals hybridizes with 3d orbital, and about one electron transfer from 4s orbital to 3d orbital. Moreover, the electrons also transfer between different atom. The results also indicate that the average bond length of clusters were determined by the 4d and 3d orbitals except Ti7. But for Ti7, the average bond length only depend on 3d orbital.

Diplopia and disturbance of ocular movement are related to the incarceration of the extraocular muscles and the displacement of orbital wall, and the management is simple relatively. However, the treatment of enophthalmos is difficult because the orbital reconstruction is made to be complicated by the complex morphous of orbital wall and the limited operative area. This study introduced the use of CAD/CAM technique in orbital reconstruction, and the result is more satisfactory than traditional methods.

However, the therapeutic efficacy is not ideal yet. There were 5 cases remained at least 3 mm enophthalmos postoperatively. The analysis of the CT data indicated that the insufficient compensation of orbital volume should contribute to the remained enophthalmos. The titanium mesh prebent with the aid of CAD/CAM technique can provide precise orbital reconstruction but can not increase the orbital volume sufficiently because of its limited thickness.
