We take sech form ansatz and solve the CNLS equations through variational approach. We obtain the analytical expression of nonlinear coupling term, which is in the lagrangian of CNLS. We apply a potential well model to analyze the interaction properties of self-trapping beams in detail, the results show that the interaction do not change the profile of the beams, two beams keep oscillating around their collective center periodically. The amplitude and period of this oscillation are both determined by initial separation of two beams.

我们采用Sech函数为试探函数，用变分法求解CNLS方程，（1）给出了CNLS方程所对应的拉格朗日中的非线性耦合项的解析表达，（2）利用势阱模型详细分析两自陷光束之间相互作用的特性，结果表明，相互作用没有改变孤子的形态，它们分别在与传播方向垂直的方向上绕它们的公共中心做往复振动，振动幅度及周期都取决于两光束的初始分隔。

This thesis is divided into two sections, in which two aspects of the field are studied respectively.

本文共分两篇，主要在两个方面进行该领域的研究工作。

Based on the samples of over 1000 listed companies at the beginning of Reform of Non-tradable Shares in 2004 and 2006, the share proportion CR1 of the largest shareholder, Z index calculated as the ratio of share ratio of top 2 shareholders and H10 index calculated as the sum of square of share ratio of top 10 shareholders, and Tobin'Q reflecting the value of target company are sele

本文以股权分置改革开始的前后两年即2004年和2006年的一千多家中国上市公司为研究样本，选取第一大股东持股比例CR1、前两大股东持股比例的比值Z指数以及前十大股东持股比例的平方和H10指数作为衡量大股东控制程度的指标，采取托宾Q值来作为衡量公司价值的指标，把公司规模、财务杠杆和第一大股东性质虚拟变量作为控制变量，建立回归方程，实证结果发现三次？

And an exact maximum likelihood registration algorithm is presented based on three-dimensional plane. This method contains two sets of partially separable variables (the actual target positions and the sensor registration errors) and provides a two-step recursive optimization algorithm to ensure fast convergence. Described by expressions:(5.26)?(5.39). It resolves the problems on Multiple-platform.

同时本文还推导出了三维立体投影的极大似然配准算法，算法包括两组部分可分的变量：实际目标位置和传感器的配准误差，利用两步递归优化算法对收敛速度进行了优化处理，实现过程可参阅式5.26～5.39，此算法解决了不同平台内多传感器配准过程中所存在的问题。

In this paper we use intraday data at Shanghai and Shenzhen stock exchange, through making economic model under simple hypothesis, to study the magnitude and the time-distribution characteristics of noise and the influence of trading frequency on noise.

内容提要本文用沪、深两市的分时交易数据，在简单的假设条件下利用计量经济模型定量研究了两个市场噪声的大小、时间分布特征以及交易频率对噪声的影响。

In this paper, we mainly study the adjacency spectrum of simple connected undirected graphs. Some results will be given in this thesis.

本文中分两个部分集中反映了作者三年来围绕一般简单连通无向图的邻接谱的界所取得的主要结果，包括两类特殊图类的邻接谱，具体结果如下： 1。

It has two confiuration formats of sinle ratio an ouble ratios an two Installation moes of plastic waistban an stainless steel waistban, an it is applicable to all the 35 mm2-400mm2 an 10kV cables.

安装时将两个半圆环卡在分相电缆上，用抱箍抱紧，与电缆于一体，和谐美观，35mm2-400mm2的10kV和35kV电缆均能适用，其抱箍有塑料抱箍和不锈钢抱箍两种。

One, A shares of H shares of the stock of negative premium only two, namely, China Ping'an and Conch Cement, the two shares inversion rates were -12% and -13%.

一，对负溢价只有两个，分别是股票A股H股，中国平安和海螺水泥，两股反转率分别为-12％和-13％。

In this investigation, the number of maternal ramets and daughter ramets, length of stolon and spacer, distributed pattern of spacer and the relationship with community quantitative character were compared and researched between the two Potentilla. This offers basic data for more discussions to ecological and phenotypic adaptive strategy of the two population.

本文就两种委陵菜种群的母株、分株数量、匍匐茎长度以及间隔子长度及其布局及其与群落数量特征的关系进行比较研究，为进一步深入探讨这两种委陵菜种群的表型适应与生态适应策略提供基础性研究数据。

This invention relates to a window A/D converter used in digital supply controllers composed of a PMOS difference input pair, a CTAT offset current generation circuit, two loop oscillators and a digital part including two n-bit counters, one n-bit comparator, one n-bit subtracter and an n-bit D trigger, in which.

本发明属集成电路技术领域，具体为一种适用于数字电源控制器的窗口式模数转换器。它由一个PMOS差分输入对、一个CTAT偏置电流产生电路、两个环路振荡器和数字部分组成。数字部分由两个n位计数器、一个n位比较器、一个n位减法器、一个n位D触发器组成。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
