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 .

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。

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。
