The result is that both tin atoms are five-coordination, have a distorted trigonal bipyramidal geometry with an additional week interaction between another oxygen atom and tin atom.

分子中四个羧酸酯基有桥联双齿和单齿两种不同的配位模式；在内环锡和外环锡的配位单元中，锡均形成具有五配位的畸变三角双锥配位构型，同时另有一氧原子与中心锡原子之间有弱相互作用。

At the late stages of the ore_forming process, the main ore_forming fluid was NaCl_H2O. According to characteristics of the fluid inclusions, high 3He/4He ratios and the existence of lots of mafic microgranular inclusions, the authors consider that the ore_forming materials of the Longshang tin_polymetallic deposit were derived from multiple sources. The ore_forming fluids were mixed with mantle, crust and atmospheric water. Under the control of igneous and surrounding rocks, the mantle ore_forming fluids played a key role in mineralization at the early stage of the ore_forming process.

根据流体包裹体特征，结合高3He/4He比值以及在锡田花岗岩中存在大量镁铁质微粒包体，笔者认为：锡田垄上锡多金属矿床成矿物质是多来源的，成矿流体为地幔、地壳和大气水的混合产物；锡多金属来源受岩浆和围岩控制，而在成矿作用过程中尤其是成矿早阶段，地幔成矿流体可能起到了积极的甚至关键的作用。

The toxicity and effects of different concentrations for two organotin compounds towards Scenedesmus obliquus were studied in this paper with CH3SnCl3 and(CH3)2SnCl2,respectively,as representatives.

有机锡对海洋环境有着很大的破坏作用，为此以一甲基氯化锡(CH3SnC l3)和二甲基氯化锡(CH32SnC l2为代表，研究了不同浓度有机锡对斜生栅藻的毒性影响，并且对两种有机锡的毒性进行了对比试验。

This kind of sulfide ore is relatively refractory and it is difficult to improve production ibexes, with high cost and low benefit. During 1988 to 2000, the per-product ability is 157.5 ton per day, primitive mineral tin grade is 1.89% and obtained 52~54% tin concentrated, with 51.06% recovery. Tin grade of 1.5% make mining and processing keep equal.

这种硫化矿比较难选，生产指标一直难以提高，处理该类型矿石生产指标低，成本高，效益差。1998年至2000年的三年间，平均生产能力157.5吨／日，原矿锡品位1.89％，产出的锡精矿含锡52～54％，锡回收率51.06％，原矿采选持平锡品位为1.5％。

By means of magnetically controlled reaction and sputtering process, metal tin is oxidized, and tin oxide film in nano level is formed on silicon chip and further oxidized and annealed to form the nano crystal particle tin oxide film. The nano crystal particle tin oxide film has the features of great specific surface area, homogeneous thickness, high surface smoothness, high sensitivity, high stability and others.

本发明采用磁控反应溅射方法使金属锡氧化，在硅片上生成锡的纳米量级氧化物薄膜，再进一步氧化、退火，即可制造出纳米晶粒氧化锡薄膜，该氧化锡纳米敏感薄膜具有氧化锡颗粒度小，比表面积大，厚度均匀等特点，且表面平整度高，在100倍显微镜下观察没有裂痕，有利于提高气敏传感器的灵敏度和稳定性，通过溅射时间严格地控制膜厚，可重复性高，适合于批量生产。
