A transaction model is proposed based on function alterative characteristic, which improves the ability of transaction suiting for real-time environment.

针对嵌入式数据库系统的实时性和高可预见性，提出了基于功能替代的事务模型。该模型改善了实时事务对动态实时环境的应变能力。

Model is the relative data which is the internal property of Object;View is external presentation form of Model, one Model can correspond to one or more View, View also possesses the function of alternating with environment;Controller is the relating ligament of Model and View, Controller picks up the external information transmitting from View and transfers to corresponding event and the update the Model.

其中MVC 设计模式分离了数据和控制，增强了框架的模块性；采用了分布式组件技术，提高了软件重用性；采用了多层的思想，把表示层、商业逻辑层和数据库层分立开来，便得系统的移植性和重用性得到了加强。

This article mainly introduce us how to carry out this system though the alternation of the asp and the Database.

本文介绍了用 asp 和数据库之间的交互实现这个彩票服务系统。

In another distributed network, the accounting, sales, production, and engineering departments of a busy-ness firm might have their own computers, with althea machines linked to a centralized mainframe housing the organizations database.

在另一个分布式网络中，会计，销售，产品和程技术部门都可以拥有自己的计算机。所有这些计算机和一台中央机相联，该主机的机房内还有数据库。

The results demonstrated that the ITS sequence analysis supported the identification based on morphological characteristics for most of species of Amanita on the species level or on the genus level.

在这种情况下，如能借助分子手段，以传统的形态特征为基本分类依据，辅以DNA序列比较分析，同时借助国际核酸数据库的大量信息资源势必将有助于鹅膏属真菌的准确鉴定。

Key words: Amanita; rDNA; ITS sequence analysis; classification and identification; Macrofungi

本研究在对采自浙江西南部丽水山区的7个鹅膏菌标本进行初步鉴定的基础上，对7个鹅膏菌的rDNA ITS区段进行序列测定和序列特征比较分析，并进一步对ITS序列进行核酸序列数据库GenBank同源性检索比对，构建起系统发育树以期为基于传统形态特征对7个鹅膏菌做出的分类鉴定提供分子依据。

Adopt ASP. NET 2003 is regarded as the developing instrument, the design of storehouse of the data follows 3 normal form :, have designed the coding schedule of goods and materials mainly, tombarthite product structure catalogue, basic information slip of the job centre, route form of the craft , project code of the expenses, journal ledger of the cost of goods, subsidiary ledger of the cost of goods, department's form, measurement unit form, the supplies inventory safeguards the counting type structure form, real expenses form, share the proportion form in power of kinetic energy, salary expenses share proportion form, amortization charge share proportion , maintain expenses share proportion , test expenses share proportion , main frame left menu tree form , material price list ,etc. data list

采用ASP 。NET 2003作为开发工具，数据库设计遵循第三范式，符合第二范式的条件，每个非关键字属性都仅由关键字决定，而且一个非关键字属性不能仅仅是对另一个非关键字属性的进一步描述(即一个非关键字属性值不依赖于另一个非关键字属性值)。，主要设计了物资编码表、稀土产品结构目录表、工作中心的基本情况表、工艺路线表、费用项目编码、产品成本总帐、产品成本明细帐、部门表、计量单位表、物料清单维护数型结构表、实际费用表、动能功率分摊比例表、工资费用分摊比例表、折旧费用分摊比例、维护费用分摊比例、化验费用分摊比例、主框架左菜单树表、材料价格表等数据表。

The pearson correlation coefficient was 0.682 of the comparision between the sea urchin and amphioxus.

数据库中收录了原始的277538条EST数据，收录了文昌鱼转录层次各方面的数据和结果(http：//amphioxus.lnnu.edu.cn/homepage.php)。

Genome sequences of Anabaena PCC 7120 are available at the CyanoBase databank.

Anabaena PCC7120的全基因组序列可以从CyanoBase数据库获得。

This is an IT enabled service where people convert analog data in digital form and create a database.

这是一个IT服务，人们能够模拟数据转换成数字形式，并建立数据库。

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
