Soil Ca2+ content increased by 0.749mmol/kg, Mg2+ content increased by 0.169mmol/kg, the Na++ K+ content dropped by 9.52mmol?kg, SO42- increased by 0.091mmol?kg, Cl- reduced by 1.727mmol?kg, the HCO3- content in the soil assumed the obvious dropping tendency, it might be explained that the advancement of HCO3- has transformed into CO32- in the oasis, and has formed precipitation with two price calcium magnesium heteropolar ,then fix in the soil layer.

4土壤Ca2+含量增加了0.749mmol/kg，Mg2+含量增加了0.169mmol/kg ，Na++K+含量下降了9.52 mmol∕kg，SO42-增加了0.091 mmol∕kg， Cl-降低了1.727 mmol∕kg，土壤中HCO3-的含量呈明显下降趋势，可解释为在绿洲化进程中HCO3-转化为CO32-，并与二价钙镁离子结合形成沉淀固定于土层中。

Tetrachloroterephthalic acid was prepared by chlorinating terephthalic acid, oleumsolvent and iodine catalyst. Tetrachloroterephthalic acid was acylated by sulphurous oxychloride in the presence of DMF to form tetrachloroterephthaloyl chloride. The acyl chloride product was fluorinated by potassium fluoride and esterified by methanol to synthesize dimethyl tetrafluoroterephthalate. The ester was reduced with potassium borohydride and lithium chloride to give tetrafluoroterephthalyl alcohol. The above product was bromated in the hydrobromic acid to obtain 4-bromomethyl-2,3,5,6-tetrafluoro-benzene methanol. 4-Methyl-2,3,5,-6-tetrafluorobenzene ethanol was obtained by reducing the bromide with magnesium. In the exist of DCC and DMAP, tefluthrin was got by the condensation reaction between 4-methyl-2,3,5,6-tetrafluoro-benzene methanol and-(1RS,3RS)- 3-(2- chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropanecar-boxylate acid.
