People for the worship of nature and the harvests were bountiful good wishes , in the heart of a structure with ma tau , antlers , and snake - body . ichthyosis , talons , tail characteristics of the creatures , and give it again given the rain cloud , the power of trouble , and this is the dragon 人们出于对大自然的崇拜与五谷丰登的美好愿望，在心中构造了一种拥有马头、鹿角、蛇身、鱼鳞、鹰爪、鱼尾等特征的神兽，并赋予它翻云赋雨，兴风作浪的神力，这就是龙。
The convergence and stability for the schemes are proved , and the error estimates are obtained . chapter 5 , consider the damped coupled generalized nonlinear wave equations . in section 5 . 2 , by coupled a priori estimates and galerkin method , prove the existence and uniqueness of the global smooth solution for the periodic initial value problem and obtain the existence of global attractors 第四章，考虑一类具耗散的广义kdv方程组的周期初值问题，在第二节中证明了整体光滑解的存在性和唯一性，得到整体吸引子；在第三节中构造了半离散和全离散的fourier谱格式和拟谱格式，在整体光滑解存在的条件下，证明了这些格式解的收敛性，并得到了误差估计。
We obtained the uniform data distribution from discrete data points by inserting spatial dots and then set up digital elevation model ( dem ) of correlative area through constructing mutual linked triangle net . the isoline graph was implemented based on this model . during the processes , we combined the technology of stratification computing when inserting special dots in fault area with the technology of stratification triangle net in fault area for dealing with thrust data 然后介绍了在本研究中构造逆断层地质等值线的基本思路：从离散数据点结构出发，采用空间数据内插方法进行数据的均匀化，通过三角剖分构造出相互连接的三角形网络结构来建立起相关区域内的数字高程模型，利用该模型构造出相应的地质等值线图，其中使用扩展点与断层区的关系属性进行断层区分层空间插值计算处理和断层区域的分层三角形网格化处理相结合的技术，实现逆断层数据的处理和等值线绘制。
3 ) we build a mathematical model of distributed concept lattice and discuss the union operation to combine two extention - independent same field lattices and the union operation to combine two intention - independent same field lattices . the experiments show that our union operation algorithm is superior to the algorithm that gets the lattice from context directly in time - consuming . for the completeness in mathematics , we also discuss the intersect operation to remove everything except the overlapping areas of two same field lattices ( 3 )给出了分布式概念格的数学模型，重点讨论了在分布式概念格的数学模型下，外延独立和内涵独立的两个同域概念格的并运算，研究高效的合并两个同域概念格的算法，实验结果表明我们的并运算算法在时间性能上要优于直接从原形式背景中构造概念格的算法。
Based on it , favorable exploration areas in wuerxun depression are predicted . the most favorable exploration areas of ktn2 are surennuoer structural zone and huangqimiao structural zone . the more favorable exploration areas are tongbomiao structural zone , wudong slope zone , wuxi fault zone , vvuzhong structural zone and bayantala structural zone . huang yi - l , suwu - 7 and suba - 9 traps ofk1p2 are considered to be the most favorable traps for oil or gas to be drilled 在综合上述研究的基础上，对乌尔逊凹陷南二段的有利勘探区进行了预测，指出苏仁诺尔断裂构造带、黄旗庙断裂构造带南部为有利勘探区，铜钵庙构造带、乌东斜坡带、乌西断裂带、乌中构造带和巴彦塔拉构造带为较有利勘探区，南二段黄? - 1 、苏五- 7 、苏八- 9圈闭是乌尔逊凹陷南二段油气下一步勘探的有利靶区。
We can give different structures on a tensor product h q to make it a bialgebra or hopf algebra . in [ 1 ] radford constructed a hopf algebra a x h with the smash algebra structure and the smash coproduct coalgebra structure , and pointed out that if a bialgebra b has a hopf subalgebra h and a projection ! : b - - > h , then there must be a subalgebra a of b such that b @ a x h is a bialgebra isomorphism 在张量积hq上可以给出不同的构造，使它成为双代数或hopf代数， radford在文献[ 1 ]中构造了以smash积为代数结构，余smash积为余代数结构的hopf代数a h ，并指出若b是双代数， h是b的子hopf代数，且存在投射： b h (即是双代数同态，且| _ h = id _ h ) ，则一定存在b的子代数a ，使ba h是双代数同构。
Active database and expert database are built up from current dbms . it provides not only functions of database management and illation but also intelligent process capability and is especially suited to applications that require both expert system and dbms , data fusion system for example 从现有数据库管理系统中构造出的主动数据库和专家数据库，既有数据库管理功能及演绎能力，又具备智能处理能力，特别适合于数据融合系统这样既需要专家系统，又需要数据库管理系统的应用。
And then we introduce bezier , b - spline and non - polynomial curves and surfaces modeling , which include l - splines , helix splines , splines in tension and c - curves etc . by analyzing the characters of bezier curves and b - spline curves , we construct trigonometric polynomial curves in the space of trigonometric functions , which assume the characters of b zier curves and b - spline curves 阐述了cagd中参数曲线曲面造型的发展历史并介绍了bzier方法、 b样条方法以及非多项式曲线曲面造型方法，后者包括l -样条、螺旋样条、张力样条以及c -曲线等。文章以b zier曲线和b样条曲线的特点为基础，在三角函数空间中构造一组具有上述两类曲线特性的三角函数多项式曲线，称其为t - b zier曲线和t - b样条曲线。
