Based on Crank-Nicoson's technique, and a new approach for the numerical simulation of the model is raised. The truncation error of the one step difference method reaches O (△t^2+△x^2) and of quite good stability condition.

基于Coriolis加速度和Lagrangian应力公式，利用Newton第二定律导出轴向加速度运动弦线横向振动的动力学模型；通过线性变换将方程化为一阶无量纲的非线性微分方程组；并利用Crank-Nicoson的中点离散技巧，给出运动方程的单步二阶差分方法；算法把对运动方程和本构方程分别离散，使之可以用于不同本构的运动弦线的数值仿真。

The prerequisite for ensuring the land rights of the peasant in the course of land circulation is to make clear the land ownership, the fundamental measures to solve the livelihood issues of the peasant who lost land is to establish the systems of household, employment and social security based on integrative governance of city and country, and to advance the citizen step of the peasant who lost land.

土地流转过程中，保障农民土地权益的前提是明晰土地产权，建立城乡统筹的户籍制度、就业制度、社会保障制度，以及加快推进失地农民市民化步伐，是解决失地农民长远生计的根本性措施。

Furthermore, a content adaptive IMC algorithm in MCTF, composed of two estimation models, is put forth to reduce the ghosting artifacts. One model is based on characteristic of subbands coefficients for low activity region estimation, and the other is to estimate the MV accuracy in high subbands from the energy after ME. Artifacts, caused by inaccuracy ME or update step, can be reduced effectively by the estimation models.

根据小波变换的子带系数特性，建立了图像平坦区域的估算模型；根据运动估计后的高频子带能量，建立了运动估计准确程度的估算模型，从而实现了具有内容自适应特性的MCTF反向运动补偿算法，减小了ghosting伪影，克服了由于运动估计的不准确以及更新步骤可能导致的低频子带反向补偿误差。

Thirdly, on the base of the existent error estimate of elliptical Galerkin projection operator, obtain semi-discrete and complete-discrete error estimates betwent EFG solution and exact solution of parabolic partial differential equation. Semi-discrete error estimate show that the rank of r is accordance with the approximation rank of subspace S_h. Complete-discrete error estimates show that it not only have relation with radius r of domain of influence, but also have relation with the step length of time variable and the way of discrete.Lastly, give typical examples and draw up procedures of MATLAB.

再次，在"椭圆Galerkin投影"算子的误差估计的基础上，对用EFG法解抛物型偏微分方程的EFG解与精确解之间作了半离散和全离散的误差估计，半离散的误差估计表明所给出的误差界限关于r的阶是与子空间S_h的逼近阶相一致的，全离散的误差估计表明所产生的误差不但与影响域半径r有关，而且与离散时间变量的步长τ及其离散方式有关。

Proceed to the next step again go further inquire into definition of Grotzach domain function, and apply qualities of Grotzsch domain function to in K-quasiconformal mappings of on extended complex plane, the angles delitational estimation theorem is obtained.

根据Grotzsch的区域函数的定义，对其概念认真分析和探讨，进而再对Grotzsch的区域函数作了进一步的研究，并把Grotzsch的区域函数的性质应用于扩充复平面上的K-拟共形映射中，获得了一个角偏差估计的定理。

The method and step of electronic seal, such as facture, registration, usage, authentication, and so on, are designed in detail.

In the midst of the activity, whatever it may be, people fall into step - sometimes two men or two women, sometimes two couples, sometimes three people - and find that they walk or play a game or tell stories or serve on a tiresome and exacting committee with the same easy anticipation of what each will do day by day or in some critical situation.

在活动中间，无论是哪种活动，他们开始步调一致---有时侯是两个男人或两个女人，有时是两对夫妇，有时是三个人。他们发现在一起走路、玩游戏、讲故事或为一个令人厌烦的苛求的委员会做事等过程中，都很容易猜想对方一天天在做什么或在某个危机环境中会怎样做。
