Moreover, A hybrid algorithm, ALHybrid, which is made of the algorithm LIDBSO and the algorithm AprioriIpv, is designed. Two algorithm, MQC_Apriori and MQC_LIDBSO, are given to mining multiple level quantitative association rules with item constrains. Two algorithm, PMARⅡ and PMARⅢ, which are based on different sequential mining algorithms, are given for parallelling mining association rules. In order to solve the mining association rules problem when we add a set of data to a database or delete a set of data from a database, two incremental updating algorithm, EUAR and EUAR, are given. Three incremental updating algorithm for association rules mining, DIUAⅠ, DIUAⅡ and DIUAⅢ, are dedigned to solve the three kinds of association rules incremental updating problem in distributed databases.

The association rules of the traditional data mining technique are used to mining higher appearance frequency and support for itemsets. If the association rules are applied to mining the outbreak symptom of excrescent disease, the support of partly outbreak symptom not high will be ridded during the mining process. The reason is that the number of excrescent disease patients is less than the number of ordinary patients. In addition, the outbreak symptom of excrescent disease may have the successively order of time happened, for example, symptom B will just take place sometime of interval later after symptom A. The data mining techniques that generally direct against the higher appearance frequency itemsets and only consider the single dimensional sequential pattern cannot totally search the pattern of outbreak symptom of excrescent disease, and cannot also provide related reference information to prescribe medicine for nursing staff at that time.

由於传统资料探勘技术中之关联规则是用来针对资料集合中出现频率较高亦是支持度高之项目集合进行探勘，若是应用於异常疾病发病徵状样式之探勘，由於异常疾病病患人数不及於普通疾病病患人数之缘故，因而造成部份发病徵状之支持度不高，将会在探勘过程中被去除，另外这类异常疾病之发病徵状可能会有先后发生时间之顺序，例如症状A发生后间隔一段时间后才会发生症状B，所以一般针对高频项目集合且只考虑到单一顺序维度之资料探勘技术，并无法完全找寻出这类异常疾病发病徵状之样式，也就无法在第一时间内提供医护人员对症下药之相关参考资讯。

This study analysised the condition of Xinjiang's petroleum resource and made an evaluation and it points out that the development of petroleum and natural gas of Xinjiang is still in the developing period in which it aims at discovering the petrol field and increasing its reserves.Although it has a great exploring potential,because of its geograghy limitation and a lack of exploring funds,the exploring level is till low,even lower than the everage level of the whole country. The study is based on theories of industry distributions,its concentration,macroscopic analysis,government regulations and continuing development.From microcosmic and macroscopic aspects,it scientifically and systematically analyses the problems in the development of petroleum industry in Xinjiang.It points that the developments of middle and upper reaches lack a balance and have no rational industry structures.So it is hard to form an integral industry chains.Moreover,the upper reach covers a too much large proportion in the development,so it can not give a strong impetus to other industries.Based it,the paper points the industrial concentration of Petroleum Chemical Products Manufacture of Xinjiang should be enhanced and Input to Petroleum Chemical Products Manufacture of Xinjiang should be increased.Due to a lack of an established fair and competitive market and government's perfect laws and regulations on petroleum industry,it points that the phenomenon of mixed operation has become common in monolopied business and competitive business,so the systems of petroleum industry needs to be restructured.It states clearly that the country should take the development and benefits of Xinjiang's economy into consideration when making strategies for petroleum development .Besides,the allocation of profits between the center and the local should be well arranged so that we can guarantee the profits of Xinjiang ,considered as a resource area.It also reveals that we should not only overcome limitations of resources,environment,economy and technology on continuring development,but also we should deal with some realistic problems well.For instance,contradictions between the concept of limited resource and continuing development,the relationship between petroleum industry's own features and continuing development,the contradictions between the limits on supply of petroleum and the need of future development of continuing resource ,outdated petroleum technology and the need of advanced technology for continuing development,tremendous damages to environment and requirements of environment protection for continuing development and Xinjiang continuing economic development,outdated policy of industry and continuing development,the relationship between continuing development of Xinjiang petroleum industry and continuing economic development of Xinjiang.

本研究以产业布局理论、产业集中度理论、灰关联分析理论、政府规制理论、可持续发展理论为依据，从微观、宏观两个层面，科学、系统、全面地分析新疆石油产业的发展问题，指出：新疆石油天然气目前仍处于油气田发现和增储的主要发展阶段，开发潜力巨大，但由于地质原因及勘探投入的不足，石油天然气探明程度偏低，低于全国平均水平；新疆石油产业产业结构布局不合理、上中下游发展不平衡，难以形成完整的产业链条，对工业的带动力与其本身具有的经济总量很不匹配；新疆石油开采业和石油加工业属于高度寡头垄断的市场类型，新疆石油化工业属于竞争型的市场结构，要想石油产业对新疆经济有较强的带动作用，新疆石油化工业必须上升到一定的层次和规模，在提高规模的基础上，提高新疆化工业的产业集中度；新疆石油加工业和化工业与农业呈现较高的关联度，加大对石油加工业和化工业的投入，对新疆经济的协调发展有着深远的影响；政府要从石油产业本质特征和发展趋势为着眼点，实施规制改革，分开政府规制政策的制定部门和监管部门职能，建立健全石油产业法律法规体系，对垄断性业务和竞争性业务实施分类规制；国家石油发展战略的制定应兼顾新疆区域经济的发展和利益，应切实处理好新疆与中央的利益分配，切实保证新疆作为资源产区合理的资源收益；新疆石油产业要想得以可持续发展，不仅要克服影响可持续发展的资源、环境、经济和技术等客观因素，还要处理好观念、需求、政策等诸多主观因素。

Firstly, it seeks the sources from which theories have been developed, by a summary of evolution or a road-map. Secondly, it explains the two basic forms taken by traditional theories on intra-industry trade, namely, horizontal intra-industry trade model and vertical intra-industry trade model. Both models take final products as trade objects and products of same industry are thus simultaneously exported and imported among developed nations and among developed nations and developing ones.Thirdly, it points out that the theory of vertical intra-industry trade has already been expanded in scope in the area of trade between developed countries and LDCs. It shows that the implication of vertical intra-industry trade has expanded to the importation and exportation of parts and components, intermediate products or processing products produced via various working procedures or different production links within the same industry, with MNCs as carriers. It gives the summary of the methods of measuring intra-industry trade and argues that the basic method adopted by this thesis is G-L Index. In addition, GHM and Input-output Analysis are introduced to demonstrate the expansion of vertical intra-industry trade.

首先，通过整理国际贸易理论的发展脉络，寻求产业内贸易的理论渊源；其次，阐述产业内贸易传统理论的两种基本形式，水平型产业内贸易与垂直型产业内贸易的理论模型，指出两者都以最终产品为贸易对象，实现了发达国家之间或发达国家与发展中国家之间的同一产业内产品的同时进口和出口；第三，结合全球化的特点和跨国公司在国际要素分工中的基础作用，指出发达国家与发展中国家之间的垂直型产业内贸易理论已经得到拓展，表明垂直型产业内贸易涵义已发展成为以跨国公司为载体的同一产业内不同生产工序或不同生产环节的零部件、中间产品或加工产品的进口和出口；最后，归纳了产业内贸易的计量方法，指出本文的产业内贸易基本计量方法是G-L指数(格鲁贝尔-洛伊德计量法)，并在此基础上进一步说明与垂直型产业内贸易的拓展相关的计量方法包括：GHM计量法和Hummels投入-产出分析法。
