With the help of the fundamental theory to singular measure differential system, Green's function matrix expression of solution and well-posed boundary condition are given, together with discussing the properties of the Green's function matrix under the influence of impulsive effect In section 5, based on Lyapunov function method, we investigate that the existence of the first boundary value problem to second-order singular system by macthing the solutions to the second boundary value problem; and the existence and uniqueness of three-point boundary value problem to third order singular system by macthing the solutions to two-piont boundary value problem.

第五部分借助Lyapunov函数法，通过将第二类边值问题的解对结成第一类边值问题的解，得到了二阶广义系统的第一类边值问题解的存在性；通过将两点边值问题的解对结成三点边值问题的解，得到了三阶广义系统的三点边值问题解的存在性和唯一性。

Research methodology adopted the foundation of Erwin Panofsky's Iconology to inspect cultural origin of peony prototype, and adopted the definition of third level to connect image of woman and peony for attempting to explain the definition of peony to maternity and family. This creation displayed there styles: remindful style, decorative style, and surreal style, and then planed three glue watercolor creative series that were "guardian series","flowerage series", and "riches as floating clouds series".

方法学上以般洛夫斯基（Erwin Panofsky，1892-1968）的图像学为基础，探讨以牡丹为原型的文化脉络，以第三层的意义将女人与牡丹的形象连结在一起，并将牡丹延伸意义为母性与家，以此为创作主轴，发展出三个风格：怀旧风格、装饰风格、超现实风格，并规划出三个胶彩创作系列：「守护系列」、「花解系列」、「富贵如云系列」。

Ion of the setting, the rest of the account is showing how, over the first three days, the problem of the earth's formlessness is solved as God shapes the creation, and how, over the next three days (and perhaps beginning on the third day, if you count the plants), the earth's emptiness is replaced by the various created things that God places in the newly shaped regions.

从这个场景的叙述，其余的记载显示，头三天中，地空虚的问题被解决了，上帝塑造了地﹔以及，在接下来的三天中（如果算植物，第三天大概也包括在内），混沌的地被各种被造物所填满，是上帝把它们安放在已经造好的区域里面。

The biological activity tests show that some target compounds have a good activity as plant growth regulator, and N-5-(3-carboxy-1H-1,2,4-triazolyl)-N'-o- chlorophenylfonnyl urea, N-5-(3-carboxy-1H-1,2,4-triazolyl)-N'-o- bromophenylformyl urea, N-5-(3-carboxy-1H-1,2,4-triazolyl)-N'-p- methyl-phenyl formyl urea have excellent activity of auxin.

生测试验证明部分酰基脲类化合物具有良好的植物生长调节活性，其中N-5（3-羧基-1，2，4-三唑基）-N'-o-氯苯甲酰基脲、N-5-（3-羧基-1，2，4-三唑基）-N'-o-溴苯甲酰基脲和N-5-3-羧基-1， 2，4-三唑基）-N'-p(或m-甲基苯甲酰基脲具有优良的生长素活性。

One of my friends and I said, he and his girlfriend together for three years, the love of the three years of fratricidal three years of each other's feelings is always sunny and the Storm in between the twists and turn, finally He said to her: In fact, not to us.

我的一位朋友也和我说过，他和女友相处了三年，相爱了三年也相残了三年，彼此的感情始终在风和日丽与暴风骤雨之间千回百转，终于他对她说：其实我们不合适。

Years ago, hold the post of when " man of fashionable and healthy ·" the thin horse of magazine chief editor is initiated first apply " 83 men section ", and the renown man of a gang China such as hook in Zhang Chaoyang, Sun Zhou, Sun Xing, Li Xiaopeng takes the lead in celebrating a festival in Beijing, this is 3 years too.

三年前，时任《时尚健康·男士》杂志主编的瘦马首次发起申办"八三男人节"，并拉拢张朝阳、孙周、孙兴、李小鹏等一帮中国名男人率先在北京过节，这一过就是三年。

The expansion coefficients Of aperture fields are Obtained after the three-dimensional arbitrary aperture fields have been represented by the sum of three-dimensional Gaussian function in the configuration-spatial wavenumber phase space.

本文利用Gabor原理把三维任意口面场表示成离散结构－波数相位空间中三维高斯基函数的叠加，将二维高斯基函数与相位空间谱双重正交的函数推广到三维，从而得到口面场展开函数。

The equation and the mathematical model are acquired just after studying of the theory of gearing, and the mathematical model also result from the actual manufacturing method. Then, the paper accomplish the accurately 3D-modeling of the four generally used types of gears: cylindrical spur gean cylindrical helical gean straight bevel gear and curved-tooth bevel gear.

利用具有强大三维造型功能的工程软件实现了四种常见齿轮：圆柱直齿轮、圆柱斜齿轮、直齿锥齿轮和弧齿锥齿轮的三维造型，解决了齿轮的精确三维建模难题。

This thesis is combined with the project－"design and exploitation of Automotive Constant Drive-Shaft", which is undertaken by the topic team. Based on the structural simplification to three-dimension solid models of ball-cage type and three column-shaft type constant velocity joint, and the three-dimension solid models are obtained by conversion engineering. Altair/Hpermesh software is used here for generating the finite element mesh of key parts of ball-cage type and three column-shaft type constant velocity joint.

本文结合课题组承担的"汽车等速驱动轴设计开发"项目，在对通过逆向工程方法获得的等速驱动轴的球笼式等速万向节和三枢轴式等速万向节三维实体模型进行结构简化的基础上，利用Altair/Hypermesh软件对球笼式和三枢轴式等速万向节的各关键零件进行了有限元网格划分。

In working, the tube via tube hoop is connected to the upper bottom plate (2); the lower bottom plate (3) is fixed to the groundsill; when the tube is vibrated, the distortion of spring can damp and adsorb the three-dimensional vibration of tube. The invention has lower natural frequency and wider temperature application, with simple structure and easy maintenance.
