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.

本文通过一系列的实验，合成了两个系列的Gemini型表面活性剂，即双烷撑双季铵盐表面活性剂m-s-m·2Br和双烷撑双季铵盐表面活性剂-s-·2Br，用红外光谱对其结构进行了表征，并且对影响合成双烷撑双季铵盐表面活性剂反应的因素进行了讨论，找出了合成双乙撑双季铵盐表面活性剂m-2-m·2Br的最佳条件：溴代烷与四甲基乙二胺的摩尔比为3.0：1.0，以乙醇作溶剂，在回流温度80℃下反应48小时；合成双烷撑双季铵盐表面活性剂12-s-12·2Br的最佳条件：十二叔胺与1，3-二溴丙烷(1，4-二溴丁烷)摩尔比为2.2：1.0，以乙醇作溶剂，在恒温80℃下回流反应48小时。

It is the real world of salt in which the roads are paved with salt, houses are built with salt,,salt mountains extend beyond the horizon and the salt sea looks just boundless…It was even incredible for us to see that scores –of-kilometer-long salt bridge called the Extended Salt Bridge floating on the brine hillof the Salt Lake.

这里真是盐的世界，盐铺成的路，盐盖成的房子，起伏不断的盐山，一望无际的盐海。。。。。。更难以置信的是湖上还有一座浮在卤水山的盐桥，长达几十公里，被人们称为"万丈盐桥"！

The big velocity difference between salt domes and surrounding rocks leads to poor reflection and distortion of salt bodies and substrata.

由于盐丘和围岩间存在巨大的速度差异，因此导致盐体本身和下伏地层在常规地震资料中出现反射品质降低、构造失真、畸变（如盐下石炭系目的层地震反射层在盐丘部位出现构造上拉现象），消除盐层的影响是含盐油气盆地勘探的重要课题。

The problem of plant's tolerance to salt is mainly the tolerance to NaCl. The research is mainly focused on two aspects: First, the study of salt-tolerance physiology in halophytes; second, the study of the injurious physiology in nonhalophytes. Thereby we can understand how to ameliorate or increase the plants'salt-resistance.

植物的耐盐问题，主要是指植物对NaCl的耐性问题，植物耐盐生理的研究，主要从两个方面入手：一是研究盐生植物对盐度的耐性生理；二是研究盐度对非盐生植物的盐害生理，从而了解改善和提高植物抗盐能力。

The multiphase tectonic activities above clearly controlled the move and gather of salifying brine, the strongth of salt-forming and the deposition of salt-bearing strata. With the pass of time, the salt-bearing strata thickened gradually from northwest to east and southeast, and the distribution of the thickness trended towards complicated; the measurement of the halite deposition extended towards east too; in the early Palaeogene and the Neogene, strong multiphase tectonic activity was a disadvantage to salt-forming, but in the middle and late Palaeogene, weak multiphase tectonic activity, which resulted in slow and sustained subsidence of the basin, was greatly advantaged to it, especially to potash-forming.

古近纪和新近纪成盐卤水的迁移和聚集、成盐作用的强弱以及整个含盐系的沉积发育明显受到上述构造活动的控制：含盐系的厚度随时间由北西向东、向南逐渐增厚，且厚度分布逐渐趋于复杂化；石盐岩的沉积规模和范围也逐渐向东扩大；古近纪早期和新近纪强烈的构造活动对于成盐作用而言是一种干扰因素，而古近纪中、晚期相对较弱、导致盆地缓慢持续沉降的构造活动对成盐，尤其对成钾作用则极为有利。
