The form discussion studies Liang Zongdai and Ye Gongchao respectively introduced and spreaded the French imagism and British and American formalism. The Poem special issue in the literature and art supplement of Ta kung Pao Newspaper and New Poetry organized twice discussions in poetic forms. The pure poetry school introduced that the modernists introduced the western and ancient pure poetry theories: from Baudelaire, Mallarme, Vale'ry, H. Read, A. Bremond to J.M. Murray, and the basic idea and difference of pure poetry. Besides, a lot of modem poets became greatly interested in pursuit heat of the pure poetry in late Tang and Nan Song dynasties, studying the development and variation of pure poetry. Music theory argues that modernists make introduction and reform on the western and Chinese music theory. He Qifang and Bian Zhilin continue the topic to the contemporary time, and put forward the theoretical frames in Chinese poetry. Rhyme and rhythm theory make researches on the introduction and reform of French symbolism and British and American modernists' rhyme and rhythm theory, making studies on the Chinese new form poetry and its thyme and rhythm theory.

Based on X-filtered LMS algorithm and -filtered LMS algorithm adaptive inverse control, we use a new variable step size LMS algorithm. Adding little computation, variable step size LMS algorithm can result in fast convergence speed and low residual error simultaneously. The adaptive feedback control can counteract the beginning error of the system. The adaptive disturbance canceler can best erase noises and disturbances.

在原来的X-滤波LMS算法自适应逆控制和-滤波LMS算法自适应逆控制方法的基础上，引入了新的变步长LMS算法，在计算量增加不多的前提下，能同时获得较快的收敛速度和较小的稳态误差；引入自适应的反馈补偿控制克服了被控系统的直流零频漂移，使控制系统在初开始工作阶段快速收敛；还引入自适应扰动消除器，它能最大限度的消除扰动。

Following such study clue, I gradually introduced the factors that should be taken into account in discretionary disclosure and integrated all the theories in a frame. Firstly, I introduced the concept of "proprietary cost" and analyzed the level and strategies of disclosure which were taken by firms.

本文按照逐步引入影响因素的方法将现有的理论串成一线：首先引入"专有性成本"这一因素，分析了专有性成本理论框架下公司选择性披露水平及决策问题；在此基础上，引入了产品市场竞争因素，分析了不同产品市场竞争环境下公司的选择性披露决策；接着，笔者又将金融市场竞争因素引入，解释了为什么上市公司事实上并非完全遵循产品市场竞争环境下的披露策略，而会出现披露的"羊群行为"。

In a disk device, a base body (10) has a drawing lever (80) for inserting a disk, a discharge lever (100) for discharging the disk, and a slider mechanism for pivoting the drawing lever (80) and the discharge lever (100). The slider mechanism has a first cam groove for sliding a first pin of the drawing lever (80) and a second cam groove for sliding a second pin of the discharge lever (100). The drawing lever (80) pivots when the first pin slides in the first cam groove as the slider mechanism operates, and the discharge lever (100) pivots when the second pin slides in the second cam groove as the slider mechanism operates.

The reconstruction problem is ill-posed, so two optimal criterions, the least module and the smoothness criterion base on Tikhonov regularization technique, are introduced into reconstruction algorithm. Many regularization parameters choice strategies are investigated, and the TPA(Two—Parameter Algorithm) strategy which is based on the Morozov discrepancy principles, is implemented in two regularization reconstruction algorithms.Numerical experiment results show that the nonnegative and smoothness constraint condition can overcome the difficulty of iteration semiconvergent, preconditioned technique can improve convergence rate and reconstruction accuracy, smoothness regularization criterion can meliorate ill-posed problem of reconstruction and enhance iteration stability, and the TPA is an effective strategy of regularization parameters choice.

数值试验表明：在共轭梯度法中引入非负约束和光滑约束改善了迭代的"半收敛"性，非负约束保证了解的非负性，光滑约束抑制了重建解的振荡现象，约束算法的重建精度与无约束算法相比大幅度提高；在约束共轭梯度重建算法中引入预优技术，可以加快算法的收敛速度，提高迭代的稳定性和重建精度；引入光滑准则的正则化技术可以有效改善图像重建问题的不适定性，加快迭代的收敛速度，提高迭代的稳定性和图像重建质量，计算正则参数的TPA算法在闪光照相图像重建中是有效的。

Although some writers use "which" to introduce a restrictive clause, the traditional practice is to use "that" to introduce a restrictive clause "which" to introduce a nonrestrictive clause.

虽然有的作者习惯于用which来引入限制性从句，传统用法是用that来引入限制性从句，用which来引入非限制性从句。

But in our insiders control transitional economy, because the shares of the companies with higher information asymmetry are overpriced, the possibility to use long term bank debt is low while if companies of this kind import long tern bank debt, the information asymmetry can be reduced. The benefit of monitoring exceeds the cost so that the corporate governance can be improved which will bring better corporate performance; shares of companies with lower information asymmetry do not get much overprice, the possibility of using long term bank debt of this kind of companies is higher while the benefit is smaller than the cost.

但在我国的内部人控制的转型经济中，信息不对称程度高的公司由于股票在公开市场的溢价程度高，引入长期银行借款的可能性反而小，其实这种类型的公司如果引入银行债务的监督，则会减轻信息不对称程度，债务的监督收益将大于债务的成本，从而带来公司治理结构的改善，最终将带来公司绩效的提升；信息不对称程度低的公司由于其股票在公开市场的溢价程度比信息不对称程度高的公司低，反而更有可能引入长期银行借款，但这种类型的公司引入长期银行借款的成本大于收益，将会导致业绩的降低。

So two methods are used to remove the local relation. One is that extremal index is introduced to POT model. The analysis showed that the introduction of extremal index improves validity and veracity of VaR based on POT model. Still VaR based on POT model introducing extremal index is invalid in low confidence level. The other is to filter returns series using GARCH model.

为此引入两种方法来消除超阈值的局部相关性：一是将极值指标引入到POT模型中，实证分析发现极值指标的引入不仅改善了POT模型估计VaR的有效性，而且还提高了POT模型估计的准确性，尽管如此在较低的置信水平上即便引入极值指标，POT模型估计VaR仍是无效的；二是用GARCH模型对收益率序列进行过滤处理。

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。
