Different forms of variations have been derived since the Baroque period, such as cantus-firmus variation, Double, ostinato variation, and constant-harmony variation. Further examples are continuous variation, sectional variation, single-theme variation, or hybrid variation in the Pre-classical era.

变奏曲於十八世纪由巴洛克时代的反覆变奏曲或定旋律变奏曲、成对舞曲的变奏、顽固低音变奏与固定和声变奏演变至古典时期的持续式变奏曲、段落式变奏曲与单一主题变奏曲、双主题变奏曲及混合式变奏曲。

Comparing DW variation of area I~III with the north hemisphere tree rings, we also find that DW variation of these three areas are all good consistent with north hemisphere climate change; Comparing DW variation with pacific decadal oscillation and temperature variation of area I~III, we also find that WD variation of area I have good positive correlation with temperature variation; while the correlation of areas II and III is not better than that of area I.

此外，I~III区干湿变化的特征与北半球的气候变化有一定的对应关系；I区的干湿变化与当地的温度变化具有较好的正相关；II区和III区干湿变化与温度变化的联系相对I区差一些；太平洋年代际涛动可能对三个区域的干湿转化均有不同程度的影响。

Meanwhile, having a good knowledge of the concept of the indefinite integral and selecting and using the indefinite integral method in the right way, is the key to put the indefinite integral calculates into practice.

不少学生对不定积分的计算总是掌握不好，究其原因，一是对不定积分的基本概念不清楚，二是对如何正确使用不定积分方法不清楚。1不定积分在计算中常用的概念1原函数的定义：若F′=f，则称F为f的一个原函数。

The indefinite integral formula of rational proper fraction function is worked out by utilizing the relation between derivation and indefinite integral, and indefinite integral is calculated by using derivative.

本文利用求导与不定积分的关系，得出了有理真分式函数不定积分公式，并利用导数计算其不定积分。

Firstly, the eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is considered. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, we prove the existence of a nontrivial solution for a class of nonlinear elliptic with critical potentialand indefinite weights in R~2. Secondly, we prove the existence of nontrivial solutions for a class of subcritical and critical elliptic systems with indefinite part in R~2 byusing a generalized linking theorem, Trudinger-Moser inequality and concentration-compactness principle.5. The existence of at least three weak solutions for discrete boundary value problem is established by using a three critical point theorem introduced by Ricceri.

首先，讨论了R~2中一类带不定权且含临界位势的二阶椭圆型方程的特征值问题，并借此特征值问题的第一特征值性质，利用山路引理及Trudinger-Moser不等式，证明了R~2中一类带不定权且含临界位势的非线性椭圆型方程非平凡解的存在性；其次，利用广义环绕定理，Trudinger-Moser不等式及集中列紧原理，得到了R~2上一类具有强不定部分的半线性椭圆型方程组在非线性项分别为次临界增长和临界增长情形下非平凡解的存在性。

In this paper, the linear indefinite equation , quadratic indefinite equation and the several special solution of indefinite equation are studied.

本文主要研究了一次不定方程、二次不定方程和不定方程的几种特殊解法。

For example, I speak to the students and the other another distinction, I have another first in the "an" and "other" Draw a vertical line. then inspire students under the Articles, The distinction between an ponder another and the other on the difference between through the analysis of two Articles 2 and indefinite pronouns between the common feature then from the indefinite article and the article migration between the different mentality out indefinite pronouns between two similar distinction.

例如，我在给学生们讲the other与another的区别时，我就先在another的&an&与&other&之间画一条竖线，然后启发学生根据冠词the、 an之间的区别去思考the other与 another之间的区别，即通过分析两个冠词与两个不定代词之间的共同特征，进而从不定冠词和定冠词之间的不同迁移思维出两个不定代词之间类似的区别。

through text analysis,this paper examines the syntactic and morphological means typically employed in introducing topics into chinese and english texts and their relations to discourse anaphora.we find that in both chinese and english the most important means for introducing the most important and accessible topics into discourse are the indefinite nps used as objects in existential-presentative sentences,and that the indefinite demonstrative adjective zheme and this can be used as an additional means to emphasize the importance of the entity introduced.however,the two languages differ in that,in english texts,apart from the above-mentioned linguistic devices,definite nps functioning as indirect objects and names functioning as subjects also tend to be used to introduce relatively important topics,and the emphatic one,in contrast to the indefinite article "a",can be used as another linguistic means to give additional emphasis on the relative importance of the topic introduced.

摘 要：本文以民间故事为语料，分析和研究了英汉篇章中话题引入的句法和形态手段及其与篇章回指的关系。我们发现，两种语言的主要相似之处为：1用作存现宾语的无定名词短语是引入篇章中最为重要和最为可及话题的主要手段；2英汉无定指示形容词this和&这么&可用于进一步强调所引入话题的重要性。两种语言最主要的差别是：1在汉语中，存现结构中的无定名词短语似乎是引入重要篇章话题的唯一形态句法手段；而在英语中，除此之外，用作间接宾语的有定名词短语和用作主语的专有名词也可以用于引入一个相对重要的篇章话题。2在英语篇章中，另有一个标示重要话题的附加手段，即以one代替a，以便进一步强调所引入话题的重要性。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
