MethodIn the pot test, 4 kinds of wild halophytes (Melilotus suaveolens L, Limonium bicolor K., Salsola collina P.and Artemisia argyi L.) were cultivated in 3 kinds of salt and alkali soils selected from the wastelands of Dagong district, Jixian county and Xiqing of Tianjin city for salt tolerance stress treatments and their physiological indexed such as proline, MAD and soluble sugar content was determined.

方法］土壤为采自天津市大港区、蓟县、西青荒地的3种盐碱土，采用盆栽试验对4种盐生植物（草木樨、猪毛菜、艾蒿和补血草）进行耐盐胁迫试验，测定其耐盐指标（游离脯氨酸、丙二醛和可溶性糖含量）。

Under the condition of salt stress, the germination percentage, germination index and sprouts growth of different Melilotus seeds had declined tendency with increasing salt content, different varieties had different salt stress reaction.

在盐胁迫下，随盐浓度的增加，各品种草木樨种子的发芽率、发芽势、发芽指数和胚芽长度均呈下降趋势，不同品种草木樨对盐胁迫的反应不同。

The effects and performances of dephosphorization of the common coagulant and the flocculants: the calcium salt, the molysite and the aluminum salt and polyacrylic amide were studied on the post-positioned precipitation of municipal sewage which was processed through biological treatment.

本实验以常用混凝剂及絮凝剂：钙盐、铁盐和铝盐及聚丙烯酰胺为研究对象，研究它们对经生物处理后的城市生活污水出水，进行后置沉淀除磷的性能及除磷效果。

To explore new synthetic methods, we set out a careful investigation of the reaction of benzimidazolium salt with many nucleophilic agents, including the active aromatic compounds and heteratom nucleophilic agents, and found that the quaternary C=N is not so active; when benzimidazolium salt is reacted with big nitrogen nucleophilic agent? phthalimide, it does not give the expected addition product, instead, produces N-alkyl phthalimide through alkyl-transfermation from benzimidazolium salt to phthalimide.

为了开发新的合成方法，研究了苯并咪唑盐与各种亲核试剂（活泼芳环与杂原子亲核试剂）的反应，发现苯并咪唑盐不与活泼芳环及杂原子亲核试剂发生2位加成反应；在与体积较大的位阻型N亲核试剂邻苯二甲酚亚胺反应时，未得到亲核试剂与极化的C＝N的加成产物，而是得到N烷基化的邻苯二甲酰亚胺，进一步研究表明，苯并咪唑盐将1（3）位N上的烷基转移给了邻苯二甲酰亚胺，并讨论了其反应机理和取代基，溶剂效应。

Through the research we have established in planta transformation system, mutangenesis and screening system for salt sensitive mutants, and constructed a cDNA library under salt stress and cloned a serious of salt-tolerance related genes which had been confirmed the function by overexpression in Arabidopsis or antisense expression in Thellungiella. We also compared different mapping strategy through the analysis of the genetic polymorphism between ecotypes, and establishing mapping population for physical mapping.

建立了小盐芥的转化体系与盐敏感突变体诱变与筛选体系，构建了盐胁迫下的cDNA文库并克隆了一批耐盐相关基因，并通过模式植物拟南芥转化与小盐芥的基因反义表达证实其功能，通过不同生态型小盐芥的遗传多样性分析探讨了基因组作图的策略，建立了作图群体并开始进行物理图谱构建。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst. The effect of the internal quaternary ammonium and/or pyridiniumsalt on the epoxidation of substituted chromenes is similar to that of the externalpyridinium salts and ammonium halides.

There was no residue or few from asphaltene reprecipitation after acidolysis asphaltene, and using fatty acids were extracted by hexane.

结果表明，相同阳离子的不同羧酸盐活化能和频率因子分布特征相似，拥有相同的均值，不同之处在于短链的比长链的羧酸盐振荡幅度宽；不同阳离子的同种羧酸盐，活化能和频率因子分布却相差很大。

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。
