The weak formulation permit is satisfied not point by point, finite element method balances only at node neighborhood, in unit balance is not required, in analytical method single check from infinite series does not satisfy the equation, but infinite number of points satisfy the equation, and then the weak formulation of dual system of Hamilton equations was educed.

基于基本方程和边界条件的弱形式，给出相应的广义变分和不同形式的有限元所采用的弱条件，说明弱形式允许不是逐点满足，有限元法只在节点邻域平衡，在单元内不要求平衡，解析法用无穷级数中单取一项也不满足方程，也是无穷多项在积分下满足，进而导出对偶体系弱形式哈密尔顿方程。

To perform CRS stack depends on the determination of three wave attributes,compared with conventional common middle point stack and dip move out stack,CRS stack can focus more energy in the vicinity of the reflector,therefore can obtain a better zero offset section by stacking events with same phase.

共反射面元的旅行时响应由三个波场属性参数确定，相比常规共中心点(commonmiddlepoin ，CMP)叠加和倾角时差校正(dipmoveout，DMO)叠加，CRS叠加算子能够将地下反射点附近一个邻域内的能量进行聚焦并实现同相叠加，因此能得到更好的零炮检距剖面。

For this purpose, a new approach for computing feature points and analyzing shape features of section contours was developed. It dealt with the sharp changes between the adjacent sections via the transition loop and accessional region.

同时，针对曲面片的分段识别，提出了基于顶点法向距离符号量的判断准则及计算方法，利用表面顶点处的切平面与其周围邻域内的顶点之间的位置关系来判断凸凹性，完成对于具有单一凸凹性质的曲面区域内的三角形面片的聚类划分。

In self-organization freeform reconstruction method based on triangulation, each pixel of an image is taken as a bion of self-organization system, and each bion and its two neighbors constitute a triangular surface patch, then this bion adjusts its state in order that the triangle element satisfies the Lambertian reflectance model.

基于三角片化的自由曲面自组织重构方法将图像中的每个象素视为自组织系统中的生命单元，每个生命单元与其相邻的两个单元组成一个三角片，该生命单元调整自己的状态，使其与邻域单元构成的三角片按朗伯反射模型满足原始灰度图像的要求。

The dissertation includes:◆General research of canonic VSC The contents are following: the cause and eliminating approach of chattering; Invariance property; the relation between VSC and high-gain linear feedback control.

讨论了产生不变性的条件；揭示了VSC与大增益线性反馈控制的等价关系；提出了用切换面邻域内的稳定性来分析抖动起因的方法。◆研究了不确定系统的VSC设计分别针对满足匹配条件但集总不确定部分上界不确知、不满足匹配条件但满足广义匹配条件、不满足广义匹配条件等情况，研究了其VSC设计问题。

A matching graph of class-buck and class-stack is obtained by a simplifying rule to guarantee the correctness of curriculum schedule. Employing the matching graph as the initial solution, Tabu search is introduced, the index of which is the weighted summation of the principle of categoricalness, rationality, and humanization.

在此基础上，引入禁忌搜索算法，以排课的完备性原则、合理性原则和人性化原则的加权和为目标函数，以随机二维权值矩阵生成的匹配偶图为初始解，对二维权值矩阵进行扰动构成搜索邻域，以生成的匹配偶图为禁忌对象，采用全局藐视准则，获得最优的排课方案。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
