Beijingensis under three droughttreatments, normal, moderate and severe stresses. The results showed:(1) the canker disease ofboth cultivars was serious gradually with increased drought;(2) the bark tissue cells sufferedplasmolysis, more evident with the severity of drought stress;(3) under the drought andinoculation with B. dothidea, cells of two cultivars damaged at different degree, mailyrepresented in the changes of organelles, such as chloroplast swollen and distorted, number ofmitochondria increased and membrane system indistinct; then organelles suffered furtherdamagement with inoculation time, thinned mitochondrias stroma, decreased cristae, crumpledand partly broken membrane of chloroplasts with stroma exosmosis. At last, the chloroplastspartly disorganized;(4) the hyphae growed mainly intercellular in resistant cultivar and notonly intercellular but also intracellular in susceptible cultivar, which directly caused thenecrosis of cells;(5) under the severe drought, the damage of cells enhanced the infection ofpathogen and drought and pathogen stressed together and promoted the disease development;the damage from pathogen on cells was more serious than that from drought.

结果显示：(1)随着干旱胁迫程度的增加，2种杨树溃疡病害发生渐趋严重；(2)干旱胁迫下，杨树树皮组织细胞发生质壁分离，并随胁迫程度的增加而严重；(3)干旱胁迫下接种病原菌，2种杨树细胞发生不同程度的损伤，主要表现为细胞器发生较大变化，如出现叶绿体肿胀变形、线粒体数量增多，质膜模糊不清等现象；随接种时间的延长，细胞器受到进一步损伤，叶绿体被膜折皱，严重时局部破裂，基质外渗，并部分最终解体；(4)毛白杨中的菌丝主要在细胞间隙中穿行，而北京杨的菌丝除在细胞间隙中生长之外，侵入细胞内部也较多，直接导致细胞的解体；(5)干旱胁迫下细胞的损伤促进了病原菌的侵染，干旱和病原菌的双重胁迫加剧了病害的发生程度，并且病原菌侵染对细胞的破坏程度大于水分胁迫。

Factor analysis is a very popular multivariate statistical analysis method. It can summarize some unobservable factors from the test results which can summarize most of the observed data. The factor analysis suggest the DP, furfuran and CO_X can be divided into insulation aging factor, while the hydrocarbon gas and hydrogen were divided into another group which can be called insulation fault factor. The result of the factor analysis

因子分析作为一种常用的多元统计分析方法，可从众多可观测变量中，概括和推论出少数不可观测的潜变量，用最少的因子去概括和解释大量的观测事实；本文将试验过程中90℃下油中溶解气体、绝缘聚合度、糠醛等参量进行因子分析，结果表明：绝缘聚合度、糠醛、CO_x被分为一类，代表绝缘老化因子：烃类、氢气、被分为一类，代表绝缘故障因子；因子分析结果与现场经验一致，相互印证，具有重要意义。

Claudio Monteverdi became the most visible of a generation of composers who felt that there was a secular means to this "modern" approach to harmony and text, and 1607 his opera L'Orfeo became the landmark which demonstrated the array of effects and techniques that were associated with this new school, called second pratica, to distinguish it from the older style or prima Pratica.

Claudio Monteverdi成为从同时代中最脱颖而出的音乐家，他认为对于和声和曲谱的阐释有一种通过新方式获得的世俗方法，接着他的歌剧L'Orfeo成为展示与被称为seconda pratica的新乐派相联系的一系列结果和技法里程碑，用以区别之前被称为第一种常规的旧风格。

磷化氢在电子工业中主要用作外延硅半导体的一种n型掺杂剂，在化学气相沉积和离子注入中被用作一种磷源，在发光二极管用磷砷化镓膜的生产中也占有重要地位。

There are two issues which have to be elaborated again: in the first place, according to their own experience in their environment, an effective experience will be regarded as a correct understanding, for the time being, it can not be considered to be an effective understanding, because the activities must rely on common sense. But common sense is often a result of collective consciousness and the mutual influence in our social environment. Second, after the people having grasped what is "reality", they also will have expectations beyond their conditions. They need a certain neglectfulness, neglecting their own responses, ignoring the "general" statements and rules that follow common sense.

这里有两个问题需要再次说明：其一，基于对身处环境的体验，有效的经验将被当成正确的认识，暂时无法被认为是有效的认识，则行为需要依赖于常识，而在我们的社会环境里，常识常常是一种集体意识的、互相影响的结果；其二，人们在产生关于"现实"的理解之后，还会产生远离自己的状况的期望，需要某种忽视，忽视自身的反应，忽视顺从常识中的"一般"说法和规则，从而产生一种浪漫情怀。

The effects of bill hypothecation include: the proving effects of right, it is the analyses about the way that the holder proves that he is the owner of the right according to the endorsement; the effect of stopping the countervailing power, it is the analyses about the way of stopping the apply of the obligator's right of defense against the pledger; the effect of transfer endorsement, i

文章的第四部分，对票据质押权人实现质权的方式做出解释和分析，1、向付款人请求付款，是主债务未到期而票据已到期时，票据质押人作为主债权人，即可以依背书的连续性证明自己权利的存在，持票据提示付款人付款的问题。2、行使票据追索权，是付款请求权的一种补充或保障性的权利，作为第二次请求权有效地起到了保障票据债权流通、票据制度规范运行的作用。3、票据届期与其所担保的债权的届期问题，由于票据的到期日与其所担保的债权的期限有所不同，所以在票据债权的实现上有异，现实中票据的到期日与其所担保的债权的期限的不同，本文就票据所担保的债权与票据的到期日同时届期、票据的到期日先于被担保债权的期限到达、票据到期日后于被担保债权的清偿期到达，这样三种情况进行分析。

In the new method for two-dimensional problems the line integrals onboundary elements are converted into the evaluation of potentialfunctions at the ends of these elements.For three-dimensional cases,thesurface integrals on the usual boundary elements are transformed,through an application of Stokes'theorem,into line integrals on thebounding contours of these elements.

边界轮廓法是刚刚出现的一种新型的边界元法，该方法的核心是利用边界积分方程被积函数散度为零的特性，对二维问题，原积分方程中沿边界单元的线积分被化为单元两端点势函数之差计算，对三维问题，将边界单元上的面积分转变为沿单元轮廓的线积分，它是一种十分简便有效的边界元新技术。
