When the aphids were feeding on Ww2730 seedlings, the time to 1st probing was delayed compared to those on Xiaoyan22 and Batis, searching was interrupted before 1st probing, and 1st probing was shorter than that on Xiaoyan22 and Batis significantly. Duration of pd Ⅱ-1 on Ww2730 and Xiaoyan22 was much longer than that on Batis. Duration of pd in C waveforms on Ww2730 was longer than that on Xiaoyan22 and Batis remarkedly. Times and duration of G waveform on Ww2730 were more and longer. Times of spot G waveform on Batis were more than on Ww2730 significantly, but the duration was shorter than those on Xiaoyan22 and Ww2730. Total time of E1 waveform, max longest duration of E1 fractions and mean duration time of E1 fractions following E2 wavefrom on Xiaoyan22 and Batis were all longer than on Ww2730 statistically. There were no differenences among mean durations of 1st E1 wavefrom on three varieties, but mean durations of other E1 waveforms on Ww2730 and Xiaoyan22 were shorter than those on Batis. The other waveform parameters, include times and durations of F and E2 were all not different on three wheat varieties.It is suggested that the resistance mechanism of wheat variety Ww2730 to S.

麦长管蚜在品种Ww2730上口针开始接触叶面时间显著晚于小偃22和Batis，第1次持续刺探前的刺探次数显著多于小偃22和Batis，开始刺入叶面后第1次刺探的持续时间极显著短于小偃22和Batis；在Ww2730和小偃22上的PdⅡ-1的平均时间显著长于Batis；Ww2730上C波阶段2个Pd波间的间隔平均时间显著大于另外2个品种；在Ww2730木质部取食的次数和时间显著大于其它2个品种；Batis上的点G波的次数极显著地高于Ww2730，而平均持续时间极显著短于小偃22和Ww2730；在Batis和小偃22上E1波的总时间，E1波的最大值、跟随E2波的E1波的平均时间均显著大于Ww2730；3个品种间第1次E1波持续的时间差异不显著，但Ww2730和小偃22上其它E1波持续的时间极显著少于Batis；3个品种上其它波形参数，包括F波的次数和总时间、E2波的次数和总时间没有差异。

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。

After rectifying the family structure, and educational level of parents, the influencing factor of adaptability was formula mainly; intensity of reaction was breastfeeding duration for 4-6 months and breast milk mainly; rhythmicity was breastfeeding duration for 7-9 months and formula only; activity level was both breast milk an formula milk equally and breastfeeding duration for 7-9 months; quality of mood was formula only and duration of breastfeeding for 7-9 months; approach-withdrawal was breast milk mainly and both breast milk and formula milk equally; distractibility was formula milk mainly.
