本文讨论了一些公钥密码体制(ElGamal加密与解密算法、Diffie -Hellman密钥交换方案和Shamir协议)在阿贝尔群上的扩展，它们的安全性均建立在阿贝尔群上离散对数求解困难性的基础之

The data transformation platform is designed in accordance with modularization, which masks the access from upper application by data wrapping module and submits DataSet objects to upper application. DataSet exchange module finishes heterogeneous data exchange by using XML capsulation of DataSet. For the synchronization process of heterogeneous data, it uses table trigger and Updates Information Table to capture change from source database table. The Update Information Table keeps the DML statements operated on tables which need to be synchronized. In the course of synchronization, synchronization module extracts DML operation field from Regenerate Information Table DataSet. At last, it updates the table fields of destination database by using command object.

数据转换平台的实现采用模块化设计，通过数据包装模块屏蔽上层应用对数据库的访问和将包装好的数据集对象提交给上层应用来实现，数据转换模块利用DataSet对XML的封装完成底层异构数据的交换；在异构数据同步的处理上，采用触发器结合更新信息表的方式获取源数据库上表内容的变化，更新信息表保存作用在同步表上的DML语句，然后在同步的过程中利用数据转换平台的同步模块对更新信息数据集中的DML操作字段进行数据抽取，最后通过命令对象将变化更新到目的数据库的表字段中。

In addition,we also discuss the boundedness results for a class of multilinear commutators generated by fractional integral operators and BMOfunctions on MK_~.

C.R.Miers has shown that the Lie triple derivation on a vN algebra M with no central abelian summands has the form D +λ, where D is an associative derivation and A is a linear map of M into its center which annihilates brackets of operators.

Miers证明了无交换部分的vN代数M上的三元Lie导子具有D+λ形式，其中D是M上的结合导子，λ是从M到它的中心Z上的线性映射且零化M中的括积。

The mechanism of vanadium removal from ammonium molybdate solution by ion-exchange was studied. It is found that V and Mo existing in ammonium molybdate solution are in the forms of V3O(superscript 2- subscript 9) and MoO4(superscript 2-), respectively, when V2O5 concentration is about 0.5g/L and the p!

对钼酸盐溶液离子交换钼钒分离机理进行研究研究结果表明，在钼酸盐溶液中V2O5含量约为0.5g/L，钒与钼在pH值为6.5~8.5的范围内分别以V3O(上标 3-下标 9)和MoO(上标 2-下标 4)的形态存在。

Cybersex occurs in "chat"lines on adult bulletin board systems, in which you exchange messages with another person who is also connected to the same system .

The technology of separation and purification of the interesting protein was studied, centrifuge the sample and get the clear supernatant, remove protein by 50％ ethanol, concentrate by drying with freezing way, remove salt and pigment by dialysing, separation with G-50 and CM-cellulose52 column, concentrate by PEG6000, The purified sample was a single band after separation by SDS-PAGE.

研究了目的阿片肽的分离纯化工艺。发酵混合物经过离心取上清，乙醇沉淀去蛋白，冷冻干燥浓缩，透析除盐脱色，聚乙二醇6000反渗透浓缩，G-50柱分离，CM-cellulose52阳离子交换层析，聚乙二醇6000浓缩等步骤后得到了较纯的目的产物，目的产物在SDS-PAGE上呈现单一条带。

We construct a Salop model to analyze three conditions: no-fee, foreign fee, and surcharge. Our meaningful conclusions mainly are: When the interchange fee is equal to ATM's marginal cost, the bank's profit could be maximized; for pure ATM businesses, foreign fee is strategy-substitutable and surcharge is strategy-complementary; for banking competition, foreign fee is strategy-complementary and surcharge is strategy-substitutable.Keywords: ATM, foreign fee, surchargeJEL Number:

本文以Salop环形城市模型分析了跨行取款不收费制、跨行费制、额外费制下银行在ATM业务上的成本收益情况，本文有意义的结论主要有：当交换费等于ATM的边际成本时，两种费制都会使银行达到利润最大化；在纯粹ATM业务上，跨行费是战略替代的，额外费是战略互补的；在银行竞争上，跨行费是战略互补的，额外费是战略替代的。
