查询词典 boundary

The boundary singular kernel method and modified penalty method are utilized to treat the velocity boundary conditions and incompressibility constraint, respectively. The arc-tangential friction model is employed to treat the contact conditions.

分别采用边界奇异权法和修正的罚函数法处理速度边界条件和体积不可压缩条件，采用反正切摩擦模型处理摩擦边界条件，推导了金属三维塑性成形过程EFGM法数值模拟的刚度方程，给出了关键算法。

Motivated by this, we consider the global behavior of positive solutions of three-point boundary-value problems for second-order differential equations, under two different kinds of boundary-value problems, using fixed point theorem, fixed point index theorem and cone theory.

本文受到文献[7]的启发，运用不动点定理、不动点指数定理以及锥理论，分别研究了两种不同边值条件下二阶微分方程三点边值问题正解的整体性。

In chapter 4, we first discussed the existence of multiple positive solutions of the second order nonsingular Dirichlet boundary value problem for impulsive differential equations by using the fixed point index theorem in cones . Next, we presented some new existence results for singular boundary value problems for second order impulsive differential equations by using fixed point theorem in cones and Leray-Schauder nonlinear alternative theorem.

第四章我们首先利用锥不动点定理讨论了非奇异二阶脉冲微分方程狄利克莱边值问题多个正解的存在性；其次我们用锥不动点定理和Leray-Schauder型非线性抉择定理，讨论了奇异二阶脉冲微分方程狄利克莱边值问题一个及多个正解的存在性。

Meanwhile, the relict stratum of Jurassic in Shanxi and Henan Province can compare with the stratum in Ordos. So we can inferred from that the eastern boundary of the basin is on the east of Luliang Mountain. However, Taihang Mountain has already risen in Indo-Chinese epoch,so the farthest place of the east boundary can only be Taihang Mountain.

同时，山西和河南等地的侏罗系残留地层与鄂尔多斯可以进行对比，可以推断，盆地的东界在吕梁山以东，而太行山在印支期已经隆起，所以盆地的东界最远只能达太行山。

In Jurassic, the western, eastern and northern boundary of the basin had changed in varying degrees, except the south- Qinling orogenic belt rising in Indo-Chinese epoch, which is an always limited boundary. The western of the basin is limited by west-edge thrust nappe belt which formed in early and mid Jurassic.

侏罗纪时，除了盆地的南界为印支期隆起的秦岭造山带外——该造山带一直是一个限定性的边界，其他西部、东部和北部边界都有不同程度变化。

As far as the legal documents of the central government are concerned, the provisions of the constitution, organic law and the law in environmental protection field are abstract and inexplicit. While combining these documents with administrative regulations and other informal sources, we find that the boundary of power of the State Environmental Protection Administration of China is very definite. But the boundary of other environmental protection administrations is unclear.

就中央法律文件对建设项目环境影响评价文件审批权的配置而言，宪法、组织法和环境保护领域法律的规定是比较抽象而不明确的，但当结合行政法规、规章以及其他规范性文件进行考察时，就会发现，中央法律文件对于国家环境保护行政主管部门审批权力的配置并不是不清楚，而是十分明确的；但对各级地方环境保护行政主管部门的权力配置则主要是授权性的规定。

This result shows that if the image of the Gauss map of an evolution convex surface with planar boundary covers some hemisphere, such a surface maybe be of infinitesimal nonrigidity for the isometric infinitesimal deformation of planar boundary.

这个结果表明如果带平面边界的凸旋转曲面的Gauss映照像覆盖了某个半球，这曲面对于保持平面边界的无穷小等距形变来说可能是非无穷小刚的。

The mild-slope equation with current effects is reformulated to an inhomogeneous Helmholtz equation. Applying the conventional boundary element method to this inhomogeneous equation, the inhomogeneous part will result in a domain integral which makes the computation complicated and messy. To improve this drawback, the DRBEM is adopted to transform the domain integral to boundary integral.

首先将含水流效应之缓坡方程式重新整理为非齐次之Helmholtz方程式，再利用Green公式改写为积分方程式，但利用一般传统边界元素法解析时，将存在一领域积分项，使得边界元素法显得繁杂且不完美，为改善此一缺陷，本文乃应用双互换边界元素法之技巧，以节省大量之数值计算时间。

In IEEE Std 1149.1, the boundary-scan description language depicts the length and structure of the boundary-scan register, the instruction binary codes and the device-identification code etc.

在IEEE 1149.1标准中，边缘扫描描述语言描述了边缘扫描寄存器的长度和结构、指令的二进制代码及器件标志代码等。

The growth of functions in these spaces depends on a weighted function ρ. We investigate the relation between growth and boundary values of the functions, and prove that a function or its radial derivative is in one of the spaces if and only if the p'integral average of the difference of its boundary value function is integrable or bounded.

研究这些函数空间中函数的增长性与边界值的关系，得到了函数或其径向导数属于相应空间的充分必要条件是其边界值差分的p次积分平均应具备一定的可积性或有界性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
