In this paper, through a series of experiments, two series of quaternary-ammounium Gemini surfactants were synthesized, namely the pair alkylene double quaternary ammonium salt surfactant m-s-m·2Br and the pair the alkylene double quaternary ammonium salt surfactant -s-·2Br. We has carried on the attribute with the infrared spectrum to its structure, and to affected the factor which the synthesis pair the alkylene double quaternary ammonium salt surfactant responded to carry on the discussion. We has discovered the synthesis pair the ethylene double quaternary ammonium salt surfactant m-2-m·2Br optimum condition: The bromo alkane and a tetramethyl ethylene diamine mole of ratio is 3.0: 1.0, makes the solvent by the ethyl alcohol, 80℃ under responds for 48 hours in the backflow temperature; Synthesis pair alkylene double quaternary ammonium salt surfactant 12-S-12 ·2Br optimum condition: 12 tertiary amine and 1, 3- propylene dibromide (1, 4- two bromines butane) a mole of ratio is 2.2: 1.0, makes the solvent by the ethyl alcohol, responds for 48 hours in the constant temperature 80 ℃ under backflow.

In the light of the paleoenvironmental significance reflected by the radiolaria, graptolite, brachiopod,sponge spicule and the rock character, its suggested that the greyish green mudstone at the basal WufengFormation of the Goujiaya section would be probably deposited in 60 to 100 meters deep water, theGuanyinqiao bed in 50 to 80 meters deep, and the radiolaria-bearing silicalite from Wufeng Formation inwater with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level changecycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascendingorder: 20～120 m, 80～130 m, about 150 m, 50～250 m, and in excess of 200 m.
