In this paper, adipate -intercalated LDHs were prepared by direct anion exchange method,acidic one step synthesis method and alkaline one step synthesis method,and were characterized by XRD and IR.

采用阴离子直接交换法、酸性和碱性条件下原位一步合成法分别制备了Mg2Al-己二酸根插层水滑石，用XRD、IR对合成的样品进行了组成和结构表征，DTA结合不同温度下焙烧样品的XRD和IR分析研究了样品的热分解过程。

Third, most magnesium alcoholates are prepared by alcoholysis.The process is based on the exchange of alkoxide groups of a metal alcoholate in the presence of an alcohol other than the alcohol corresponding to the original alkoxide,i.e.on the alcoholysis of a metal alkoxide with a different alcohol. Primary alcoholates can be prepared by this process,such as magnesium di-n-propanolate,magnesium di-n-butanolate,magnesium di-isobutanolate.

该方法适用于较高沸点的伯醇的醇镁化合物，例如正丙醇镁、正丁醇镁、异丁醇镁等，但是用醇解法制备出的叔丁醇镁，其纯度只有80％，这是由于叔丁醇具有较大的空间位阻效应，阻碍了醇交换的进一步进行，并且叔丁醇沸点与甲醇相差不大，使得甲醇难以快速蒸出，只能得到一种混合醇盐产物。

Statistical multiplexing and fast packet switching are adopted by Asynchronous Transfer Mode which has the advantages of flexibility and higher bandwidth efficiency.

对突发业务进行统计复用可以获得很高的频带利用率，采用快速分组交换技术能做到真正的"业务综合"。

We found a lot of "good" things: Pai Qishan and the principle of exchange of hot and cold air base station to replace the engine room inside the air-conditioning, to achieve the effect of reducing power consumption, it is really a good idea; education in remote video platforms around the Zu Buchu school teachers teaching skills can be a PK, saving a lot of traffic and the cost of the emissions, conditional schools should have no reason to reject it; use of SMS, MMS study the "scientific concept of development", certainly than Daidai De-in the office listening to read documents more effective leadership, Why not

我们发现了很多"好"东西：用排气扇和冷热空气交换的原理取代基站机房里面的空调，从而达到降低电力消耗的效果，这真是一个不错的主意；在远程视频教育平台上各地的老师足不出校可以进行教学技能大PK，节省了大量的交通成本以及带来的尾气排放，有条件的学校应该没有理由拒绝它；利用短信、彩信学习"科学发展观"，肯定比聚在办公室里呆呆地听领导读文件更有效果，何乐而不为？

The exchange film can be used in micro direct carbinol fuel battery with high stability good for reducing battery sizes to improve utility of micro liquid fuel materials.

使得用本发明进行改性处理的质子交换膜可用于微型直接甲醇燃料电池，可使微型甲醇燃料电池稳定性得到提高，有利于单体电池尺寸的进一步减小，促进微型液体进料直接甲醇燃料电池的实用化。

The method uses water to boil pure heavy law to undertake to Tibetan angelica polysaccharide thick carry, with Sevag reagent and shade, cation commutative law contrasts rarefied thick polysaccharide.

方法采用水煮醇沉法对西藏当归多糖进行粗提，用Sevag试剂和阴、阳离子交换法对比纯化粗多糖。

The agriculture soils of Baimahu ,Lushan and Zoujiao are the typical cases in the suburbs of Changde. Rice soil and vegetable plot are the two typical agriculture soils, we collected 6 samples according to the scientific method in these three areas. After air dry, contuse, screen and make soil samples, we tested their 9 indexs of PH, organic-substance, total phosphorus, quick-acting phosphorus. Then analysed the fertility condition of these areas. Then apply feasible suggestion of fertilizer after putting forward science and suiting measures to local conditions etc, by Compare with the documents and materials. Absorb to Model TAS-986 atom spectrophotometer examine with flame law (air - acetylene ) terms of potassium make deep discussion especially.

白马湖，芦山乡和陬郊的耕作土壤是常德市郊区耕作土壤的典型代表，在这三个地区分别就水稻土和菜地这两个基本的土地耕作类型按科学的方法共采集了6个样品，经过风干，研碎，过筛制成土样后，测定了它们的PH，交换性酸，有机质，全磷，速效磷等9指标，从而对该地区耕作土壤肥力状况进行分析，对比文献资料，总结分析结果，针对不同地区不同的土壤状况，提出了科学施肥，因地制宜等可行性建议，尤其是对TAS—986型原子吸收分光光度计用火焰法测钾的条件作了深入的探讨。

This paper introduced the main Tibetan coding methods at home and abroad, and described mutual conversion from nonstandard to national standard（GB18030）,national standard to international standard according to different cording structure, and then realized it on Vista platform. It provides convenient tool for information exchange and processing in Tibetan and lays a foundation for the further development of Tibetan information.

介绍了国内外主要藏文系统的编码方案，并根据三种不同类型的编码结构，对非标准藏文编码到国家标准（GB18030）的转换，国家标准和国际标准（ISO/IEC 10646）之间的相互转换进行了详细阐述，并在Vista平台下实现了转码程序，为藏语信息交换处理提供方便宜用的工具，为藏文信息的进一步研究奠定了基础。
