可行性研究

This paper introduces the background knowledge of heterogeneous data integration, as well as the knowledge of data integration. On the basis of the above, The author develops an ontology-based Heterogeneous data Integration prototype system, expounds the main framework and essiontial technology. Then the paper introduces its work in detail: it explains the very significance of using ontology as an comon semantic description and an global query model ,and illustrates the reason fo adopting LAV method ; then it builds the formal representation of the mapping between ontology and data resources, applies OWL to describe the ontology and the mapping ; defines a query language named by DIQL to query on our integration system , and supply the detailed arithmetic of reolving partial binding of LAV method、locating of data sources and query rewriting,etc. Finally,the paper demostrates and proves the result of research by examples .

本文介绍了目前异构数据集成的研究现状以及数据集成和本体的相关背景知识，并在此基础上设计开发了一个基于本体的异构数据LAV集成原型系统，同时对原型系统的总体框架、关键实现技术分别做了讨论：首先阐述了将本体作为公共语义描述和全局查询模型的意义，给出了采用LAV集成方案的理由，然后规定了本体和数据源间映射的形式化表示方式，采用能结合描述逻辑和框架系统的优点、适合于半结构化环境的OWL表示本体和映射；其次定义了一种针对集成系统的查询语言DIQL，并在此基础上给出解决LAV部分绑定问题、数据源定位以及查询重写的算法；最后在原型系统的基础上，通过实例验证本文所提方法的可行性。

In this thesis the using BOS technology is put forward for the solution of such problems. On the basis of abundant theoretical research, with the support of relevant teachers, a laboratory for of the original equipment was established to testify the feasibility, reliability and security of the technology. Through the development and testing of different types of financial software, it is proved that BOS technology can be applied in the building of efficient and securely operating software in Intranet sphere. It is very encouraging to find out that by making use of the original equipment and some useful part of the original software, this approach has very good realistic significance and accessibility.Song Xiaohua DIRECTED BY Li Leming

针对这种情况我提出了利用BOS技术解决这一问题的方案，做了较多的理论研究，同时为了证实技术的可行性、可靠性和安全性，在有关老师的支持下利用原有的设备筹建了一个瘦客户机实验室，对不同类型的财务软件进行了开发和测试，结果证明可以利用BOS技术构造高效、安全的运行于Intranet（甚至是Internet）领域的财务软件，同时令人高兴的是这种方式可以较好的利用原有的设备、很好的继承原有的软件中还适用的部分，具有非常好的现实意义和可操作性。

Because malates specially location in the process of organism metabolism and can its beneficial effect to sports ability, the purpose of this investigation is to probe into the different influence malate ingestion on glycogen store, aerobic metabolism and blood urea metabolism when malate, oligosaccharide and FDP were ingested at the same time or alone, and furthermore to provide feasibility reference to utilize malate for athletes.66 male mice were divided into contrast group, malate group, malate oligosaccharide solution group, malate complex nutrient solution.

鉴于苹果酸在生物体代谢过程中所处的独特地位，以及它对机体代谢和运动能力的有益影响，本研究的目的在于探讨分别或同时补充苹果酸、低聚糖和FDP时，苹果酸对小鼠糖储备、骨骼肌有氧代谢及血尿素的不同影响，以便阐明它的作用机理和使用效果，为体育实践中应用苹果酸提供了可行性依据。

Diabetes mellitus is a kind of chronic and worldwide disease, and tight glycemic control is critical in manging DM and preventing complications such as nephropathy, neuropathy and retinopathy. In order to relieve DM patients pain and decrease the risk of crossinfection, noninvasive ways to monitor blood glucose concentrations are preferred, and one approach is to monitor glucose concentrations in tear fluid. This review covers recent understanding of features of tear fluid and relevant changes in DM, the influence of different collecting methods in tear glucose concentration, and attempts to monitor tear glucose concentration in situ by using contactlens based sensing devices.

糖尿病（diabetes mellitus，DM）是一种慢性疾病，也是一种全球性疾病，糖尿病患者长期理想控制血糖有助于防止或延缓糖尿病肾病、神经病变和糖尿病视网膜病变等慢性并发症的发生，为了减少患者的痛苦和降低交叉感染发生的危险，人们想到了通过泪糖浓度这一无创指标来监测血糖控制情况的可能性，我们综合近年的相关研究进展，从泪液的特性及糖尿病患者的相关改变、不同收集方法对泪糖浓度的影响及检测泪糖浓度的产品等方面进一步探讨泪糖浓度作为糖尿病病情评价指标的可行性。

Through a multidimensional compared to prove the feasibility and reliability of in vitro drug metabolism platform of human and rat liver microsomes.

Results showed that amino acid cheleted iron was molecular coordination compounds in liquids and had low molar conductivity, Among them, methionine chelated iron and glycine chelated iron was stable in pH 2.0~6.0 solution, the histidine cheleted iron was stable in pH 2.0~8.0 solution .

为探索更有效的脱酸方法，实验研究了在固相体系中气流A脱酸的可行性，结果发现，气流A既能起到很好的脱酸效果，又能缓慢地引发螯合反应，维持反应体系温度的稳定，其脱酸率达到94.60%。

While traditional farming experiences and preliminary experiments on minimum tillage showed a preference of alternating furrow slice inverting and deep loosening without inverting in some of the agricultural regions in China, the development of a PTO driven furrow slice inverting rotary plow as primary tillage implement inplace of the conventional moldboard plow was justified from the standpoint of less tractor traffic, less soil compaction, less energy consumption, sowing in time etc.

从翻耕或翻耕与深松相交替将在相当广大的地区、相当长的时期内，作为一种基本的田间作业环节而存在这一认识出发，用&假想旋翻垡片&的概念研究了旋翻在几何尺寸上的可能性及其限制条件，并从保省耕作法的节能、赶农时、省人工减少土壤压实、经济高效等方面对旋翻进行了考察，指出发展一种动力驱动、原沟旋转翻垡的基础耕具的必要性和可行性。
