查询词典 tin

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.

研究结果表明： Tin(n=2~7)团簇都依带帽的形式在前一个团簇的结构基础上加一个原子变化而来；通过自然轨道分析发现，团簇原子的轨道存在sp-d杂化，有大约一个电子从4s转移到了3d，原子之间亦存在电子转移，而且除Ti7外，团簇键长由最外层4d轨道电子和3d轨道共同决定，在Ti7中，团簇键长由3d轨道决定。

In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.
