Its structure and property have not been understood clearly. Polyimide wear-out and breakdown can occur under long-term electric stressing due to many different reasons, making their insulating life ended. Wear-out and breakdown of polymers are closely related to the dissipation of electrostatic energy in space charge region.

聚合物的老化和击穿与空间电荷区域静电能的释放有关，电致发光代表材料中分子受激的化学活性强的状态，是能量耗散的方式之一，可作为材料预击穿及结构老化的先兆，是研究聚合物分子中的陷阱结构和它所控制的空间电荷的存贮和输运特性的重要实验手段。

The results demonstrate that a greatly increased bioavailability of As under the flooded conditions is the main reason for an enhanced As accumulation by flooded rice, and growing rice aerobically can dramatically decrease the As transfer from soil to grain.

这两种硅运输蛋白都在根部表达，其中一种称为Lsi1的蛋白是亚砷酸盐进入水稻的门户，而另一种称为Lsi2的蛋白控制着从根部到茎再到谷粒的流动。这组研究者还发现硅酸—含有硅、氢和氧—会干扰亚砷酸盐的摄取。他们提出，增加土壤中可利用的硅，可能会减少从土壤和灌溉用水到水稻的砷的运输。（生物谷Bioon.com

On the base of applied tech. and system structure, the key tech. are expressed in detail. It includes:Knowledge representation technology: it is described in two stages by "Depictive frame + Rule group"."Depictive frame" is used to reflect the factors concerning question field."Rule group" reflects the son-question in question field; knowledge management system: it is made up of knowledge-base editing component, factor classifying component, knowledge inspecting component and extractive knowledge component; uncertainty reasoning adopt method of elicitation search strategy and data drive controlled by member knowledge. It take reliability of compound proof at first. That can resolve the matching contradiction. Reasoning explanation introduce pre-text and followed method of resolving path. Knowledge discovery component take SLIQ as basic arithmetic. It provides classification model in two stage forms which aim at training suit. That is decision tree and productive rule.

在确定应用技术与系统结构的基础上，重点阐述了本文的核心技术，这包括：知识表示技术，采用&描述框架+规则组&的层次结构，&描述框架&用于描述问题域所涉及的因素，&规则组&反映问题域内的子问题；知识管理系统，由知识库编辑构件、因素分类构件、知识检测构件和知识求精构件组成；不确定性推理机采用启发式搜索策略，元知识控制的数据驱动，以复合证据可信度优先作为匹配冲突消解的策略，推理解释采用预置文本与求解路径追踪的方法；知识发现，采用SLIQ快速可伸缩算法，分类模型用判定树与产生式规则两种形式描述。

Because the medical corporations faces a complexity market, and the process of produce is also a complexity system, you must face a lot of puzzle and problem in the process of information, such as inconstant requirement of the customers, quick movement of the market, variety breed and changeable process, incontrollable term of delivery and quality of goods, illogicality of the ability of the software and the excessive expectation of the user. J2EE (Java2 Enterprise Edition) standard, founded by Sun Microsystems in 1999, contains a whole suit of standard and criterion for enterprise level applications. It has many advantages, such as independence of platform, easy expansibility and good security, which makes it very popular in IT industry.

由于药品生产企业面对着一个复杂多变的市场，而药品制造过程本身也是一个复杂的系统，所以其信息化过程中需要面对大量的难题，比如：难以预测的顾客需求和市场的快速变化、不断碰到的品种变化和流程改变、难以控制的交货期限和货物品质、不可调和的软件处理能力和使用者的过高期望等。J2EE（Java2 Enterprise Edition）是Sun公司1999年推出的基于Java的一整套企业应用开发标准和规范，具有跨平台的互操作性、可扩展性、安全性好等特点，迅速得到了业界的广泛支持。

1、It is showed that, health education need to be carried out urgently, widely, deeply and continually in HIV infectors' neighbors and common people in Shanxi Province. 2、Currently, health education to HIV infectors' neighbors and common people should pay more attention to care for HIV infectors, correct misapprehensive and teach prevent measures. 3、 we should take acceptable ways to develop health education, for example: develop affection of media, and dredge hot phone etc. 4、To control HIV infect rate, in the next phase, we should expansion education of safe sex and advocate sex morality.

1、当前，需要在我省感染者周围人群和一般人群中及时、广泛、深入、持久地开展艾滋病健康教育。2、现阶段，我省感染者周围人群的健康教育应注重对感染者的人文关怀、纠正人群对非艾滋病传播途径的误解、开展艾滋病预防措施的教育。3、健康教育应采用易被人群接受的方式，如大力发展媒体作用、开通咨询热线等。4、应积极在各人群中开展安全性行为的教育，提倡性道德，从而控制HIV和其它STD的感染率。5、应努力改善感染者周围人群医疗服务状况，重视感染者及其家属和感染者周围人群的生殖健康需求，为他们提供方便可及的医疗卫生服务。

Base played a crucial role in this reaction: in the Pd2/L1 catalyzed α-arylation of ethyl malonate, K3PO4 is the base of choice; in the α-arylation of ethyl acetoacetate, K2CO3 is the most effective base.

在这类催化反应中，碱的选择具有重要的影响：以K3PO4为碱， Pd2/L1催化体系在丙二酸二乙酯的α-芳基化中，富电子溴代芳烃显示较好的活性； Pd2/L1催化的乙酰乙酸乙酯α-芳基化时，以 K2CO3为碱，催化体系显示较好的活性，这个催化体系可控制反应得到α-芳基乙酰乙酸乙酯，而不是脱乙酰基的产物。
