新疆阿克苏地区是中国重要的产棉基地,探究人为可控的物化投入对提高棉花产量的影响有着重要意义。以阿克苏市和库车县作为研究对象,利用两地1988—2009年的棉花产量和物化投入资料进行统计分析;阿克苏地区的棉花单产和物化投入（单位面积化肥施用量、单位面积农业机械总动力、单位面积农村用电量）均呈逐年增加趋势,但近年物化投入的边际棉花产量开始下降;该地区综合物化投入指数每增加1%,棉花单产增加约5.4～5.5 kg/hm2。现应科学合理地分配物化投入量,适当调整投入比例,以促进阿克苏地区的棉花产业得到进一步的发展。

The Aksu District, Xinjiang was an important cotton region in China. It was important to study the impacts of controllable materialized inputs on cotton yield. Based on the statistical data of cotton production from 1988 to 2009 in Aksu City and Kuqa County, the influence of materialized inputs on cotton yield in Aksu District of Xinjiang were analyzed through mathematic statistic method. The cotton yield and materialized inputs (fertilizer application amounts per unit planting area, gross agricultural machinery power per unit planting area, rural electric power per unit planting area) increased year by year, but the marginal cotton yield had been reduced in recent years with the increased amount of materialized inputs. When materialized index increased by 1%, the cotton yield increased by 5.4-5.5 kg/hm2. Nowadays, it was imperative to distribute scientific and reasonable materialized inputs and adjust the investment proportion for the further development of cotton industry in Aksu Dis

为有效保证客户端物化视图与数据源的一致性并降低网络开销，提出一种物化视图增量维护方法。采用XML物化视图远程增量维护方法，通过系统原型设计、系统部署、同步机制，实现试验任务数据接口同步。结果表明：在不影响试验任务数据处理与传输的实时性及可靠性的条件下，XML物化视图远程增量维护系统可有效实现指挥显示系统数据接口的一致性、可靠性和安全性。

OLAP(Online Analytical Processing)查询常常涉及到不同的维表和事实表,要得到查询结果通常需要进行多张表的连接操作。连接操作是一种非常耗时的操作,因此,如何提高OLAP查询效率成为数据仓库应用中的关键问题。文中对存储过程、索引技术、物化视图等几种常用的OLAP查询优化方法进行性能分析,针对特定应用通过反复实验比较得出物化视图的优越性。而就物化视图而言,其本身有优越性的同时也存在一些缺陷。因此,针对物化视图更新问题提出了几种更新方案。

OLAP query often involves different dimension tables and fact tables,to get the query result usually requires more table join op-erations. The connection operation is very time-consuming,consequently how to improve the efficiency of OLAP queries becomes the key problem in data warehouse. Analyze several OLAP query optimization techniques like stored procedure,index technique,and materi-alized view,take the superiority of materialized view by doing experiments in application-specific system. And in terms of materialized views,it has the superiority,also has some defects. So,the several methods to solve the update problem of materialized view are pro-posed.

在前资本主义社会，人与共同体的关系表现为一种自然的依赖性。随着这种依赖性关系的解体，人的存在方式呈现为二重性。这种二重性构成资本主义物化社会关系的主要特征。物化的社会关系是资本主义社会存在、运行和发展的基础。由于资本本性的驱动和历史使命的内在要求，人类社会最终会扬弃物化的社会关系，克服直接的“自然必然性”的束缚，实现人的全面自由个性。

In previous capitalist society, the relationship between people and the community is a natural de-pendence. With the disintegration of this dependency relationship, human existence is rendered as a duality. It constitutes the main features of the materialized social relations of capitalism. The materialization of social relations is the basis for the existence and development of the capitalist society. Due to the drive of capital nature and the completion of the historical mission, society wills eventually tight materialization of social relations to achieve the comprehensive free personality.

以青海省察汗乌苏-乌龙滩地区开展的1:5万区域物化探成果为基础,并依据区域成矿地质背景、物化探异常分布特征,结合研究区地层、侵入岩、构造、矿床(点)分布、区内已知矿床的成因类型、以及在异常查证工作中发现的与成矿有关的信息,对各种控矿因素和物化探异常进行对比分析进行成矿远景评价研究,预测出I、II、III级多金属成矿远景区4处。

Based on the 1:50000 regional geophysical and geochemical techniques achievement of Qagan Us-Wulongtan Region in Qinghai Province and geological setting and geophysical and geochemical abnormality, combined the strata, intrusive rock , structures, distribution of the deposits (spots) , known genetic type of ore deposits and information related of ore-forming found in anomaly survey, Metallogenetical prospect evaluation has been studied through comparative analysizing metallotect and geophysical and geochemical techniques abnormality. There are four polymetal Metallogenetical prospects graded into I、II and III have been predicated.
