根据物质平衡原理和达西定律，考虑基质和人工裂缝作用下三维三相渗流模型，并考虑了重力作用影响，结合应变孔隙度模型、应变渗透率模型，建立了流固耦合整体压裂数学模型。

The herbicides in the sample was extracted with ethyl acetate. The extract was decanted into a flask through a filter paper, then the filtered solution was concentrated to dry. The dry sample was dissolved and added to 5 mL with acetone-n-hexane (30:70, V/V). It was cleaned up by Florisil, concentrated again. The sample was dissolved and adjusted to 1mL with acetone.

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。
