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％。

In the contaminated lard sample, 6 organic compounds have been thus identified to be the raw materials or byproducts in the production of organic tin compounds. Based on the identified contaminants, it can be postulated that the chemical structure of the organic tin compound is dibutyltin-bis-(2-isooctyl thioacetate). The method is simple and precise, and has not been reported in the local literature.Keywords Organic tin compound, Lard, SPME－GC－MS

经过摸索研究，采用固相微萃取方法富集挥发性杂质，直接注入色谱中，经色谱分离，质谱测定，确定了杂质的结构，由杂质成分推断生产有机锡所用的原料，然后判断合成路线，最后确定有机锡的结构，从有毒猪油中鉴定出2－巯基醋酸异辛酯、双（2－醋酸异辛酯）二硫、双醋酸异辛酯硫醚等6种与有机锡有关的杂质，并与相应的有机锡工业品对照，发现工业品中也含有这些杂质，与其合成过程的原料及副产物相符，从而确定有机锡化合物为二硫代醋酸异辛酯二丁基锡。

The differences of the micro structure and properities of the bulk sinters, between the fabrication methed of powder metallurgy and reactive synthesis for silver tin oxide composite, are studied in prensent thesis. With the increase of the tin oxide content in silver matix, the electric conductivity of the composite tended to decreace. While in the same tin oxide content, the electric conductivty of the composite fabricated by reactive synthesisis better than that by powder metallurgy. One of the reasons is that the regular net structure existing in former composite.

研究了两种方法即粉末冶金法和反应合成法制备的银氧化锡复合材料烧结坯在组织上的区别和性能上的差异，两种方法制备的银氧化锡复合材料，随着氧化锡含量的升高，材料导电性均呈下降趋势，而相同成分的材料，反应合成法制备的银氧化锡复合材料的烧结坯的导电性要优于粉末冶金法，有规则的网络状组织结构是反应合成法制备的烧结坯导电性好的原因之一。
