The characteristics of the salt formation in Tarim Basin is deep, high temperature and high pressure, easy to result in the undergauge, collapse, drill bit or pipe sticking.

针对塔里木盆地石炭系盐层埋藏深，温度高，地层压力大，极易发生&缩径、坍塌&，造成卡钻，同时由于盐岩层的塑性蠕动，形成不规则井眼，甚至造成套管挤毁变形事故，井身质量难以控制，固井质量难以保证等问题，通过对同类型已钻井进行总结分析，提出了一系列钻井技术措施，并在T726井严格实施。

Well drilling in a salt formation is a problem in drilling,while accurately establishing the mud density and undersaturation is the key for solving the problem.

盐层钻井是钻井技术中的难题，准确确定钻井液密度及含盐欠饱和度是解决难题的关键。

The source and formation mechanism of methyl carbamate in liquor covered the followings:①methyl carbamate formed by spontaneous chemical reaction of carbamide and methanol in fermented and undistilled alcoholic beverage;②in alcohol produced by grains as raw materials, cyanide precursor of grains formed into cyanate during fermentation and distillation, which further developed into methyl carbamate in alcohol.

白酒中氨基甲酸甲酯的来源和形成机理主要有：①在已发酵的和未蒸馏的酒精饮料中尿素和甲醇自发的化学反应生成氨基甲酸甲酯；②以谷物为原料生产的酒精中，氨基甲酸甲酯形成的途径来源于谷物的氰化物前体在发酵和蒸馏时反应形成的氰酸盐，氰酸盐在酒精中转化为氨基甲酸甲酯。

The strategies for adaptation of halophytes to saline and arid environments during seed germination stage:(1) high salinity and temperature induce seeds to remain dormancy. Compared with Haloxylon persicum, more viable ungerminated seeds of H. ammodendron and S. physophora submerged in 700 mmol.L-1 NaCl can germinate rapidly when environmental conditions are favorable.

盐生植物种子萌发期间适应盐渍和干旱环境的策略表现在：(1)高盐和高温诱导种子休眠。700 mmol·L~(-1) NaCl浸泡后，与白梭梭相比，梭梭和囊果碱蓬有更多的未萌发的种子能够保持活力，在清水中快速萌发。

Salt or unsalt, optional.

加盐或不加盐皆可。

Vacuolar H+_ATPase showed higher correlation with plant salinity tolerance because of its contribution to salt ion compartmentation.

本文综述了高等植物细胞ATPase在盐胁迫下的活性变化及其调控机制。V型H+_ATPase与细胞离子区隔化和植物抗盐性密切相关。

The modified nanofiltration showed a good retention to salts and the retention of the membrane to high valent cation and low valent cation was 95% and 65%, respectively.

荷正电纳滤膜对盐溶液有很好的截留，对盐溶液中的高价阳离子和低价阳离子的截留率分别为95%和65%。

The results showed that both of the chlorophyll a and total chlorophyll contents decreased under the stress of neutral salt. The changes of the chlorophyll b was not obvious and a/b not consistent. The chlorophyll a and total chlorophyll of R. pseudoacacia appeared an increasing decliningincreasing trend under the stress of mixed salt. The chlorophyll a and total chlorophyll of F. velutina increased under the stress of mixed salt. The changes of the chlorophyll b was not obvious either and a/b appeared a rising trend.

结果表明在中性盐的胁迫下，刺槐和绒毛白蜡总叶绿素和叶绿素a的含量随盐胁迫程度的增加而降低，叶绿素b的变化较小，叶绿素a/b并不呈现单一的变化趋势；在碱性盐的胁迫下，刺槐总叶绿素和叶绿素a的含量随胁迫程度的增加呈现先升高后降低再升高的趋势，绒毛白蜡总叶绿素和叶绿素a的含量随胁迫程度的增加而上升，叶绿素b的变化较小，叶绿素a/b都呈现上升的趋势。

The germinating tests were performed on Fraxinus velutina seeds from saline land and none-saline land under different NaCl stress. The germination indexes and the biochemical indexes of the seedlings were measured for studying the differences of germination abilities and protective enzymes between two kinds of the seeds under NaCl stress.

将盐碱地和非盐碱地上采集的绒毛白蜡种子在不同盐胁迫下做发芽试验，测定两类种子的发芽指标和幼苗的生理生化指标，比较它们在不同盐胁迫下的发芽情况、幼苗保护性酶活性、可溶性蛋白和丙二醛含量的差异。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
