讨论了激励价控策略的激励效应与以用户盈余函数的扩展函数为曲边的曲边梯形面积的关系，给出了激励价控策略对用户激励效应的性能指标，以及一个激励策略比另一个激励策略更有效的定义及其判断定理。

In this paper, on the base of paraxial approximations, we present a set of absorbing boundary conditions of 3D elastic wave equations and apply to the 3D elastic wave numerical modeling in isotropic medium.

本文基於傍轴近似法提出了计算三维弹性波方程的吸收边界条件公式，表示了各边界面、边棱和角点处波场所满足的单程波方程，并在三维弹性波数值模拟中进行了应用。

Excitations from localized states to the conduction band account for the absorption edge shift toward lower energies observed in the case of N/TiO_2 with respect to pure TiO_2.Mixture of visible light absorption of nitrogen doping and oxygen defect gave no obvious onset in the whole range between 400 and 800nm were observed of the samples N/TiO_(2-)A and N/TiO_(2-)M.

UV-VIS-DRS分析掺杂N/TiO_2结果表明，N/TiO_2-H和N/TiO_2-T两种催化剂在490nm处有吸收带边，可见光激发途径是掺杂的N以填隙方式形成的杂质能级吸收电子发生的跃迁引起的；而N/TiO_2-A和N/TiO_2-M两种方法得到的N/TiO_2在整个可见光区域内具有可见光吸收，没有显著的可见光吸收带边，其对可见光的激发途径是掺杂N和氧空缺共同作用的结果。

Look for it in your dictionary, and while you are looking, murmur somewhat abstractedly,"Is that a preposition or a participle?"

你便到你的字典里去查找这个词，边查，边心不在焉地喃喃自语："它是前致词，还是分词？"

This often requires adding edges and creating new triangles to ''stitch'' the edges of abutting objects together seamlessly.

这经常要求我们增加边并创建新的三角形来"缝合"邻接物体的公共边，已达到无缝效果。

In this paper three different types of colorings are studied, which are incidence coloring of graphs, acyclic edge coloring and strong edge coloring.

本文研究了三种不同的着色：图的关联着色、无圈边着色和强边着色。

This article introduces the technology of trimming the aditus department of the thin-wall barrel-type piece based on the principles of transversal truncation about the polyurethane rubber.

基于聚氨脂橡胶横向截切原理介绍了薄壁筒形件口部修边的工艺方法，根据其剪切机理研制了修边模具，叙述了模具结构及主要工作零件的设计。

In addition, we show that the entities such as the length-ratio of two adjacent sides and the including angle of two adjacent sides of the parallelogram, since they are not projective invariants, cannot provide any additional useful constraints on the pose parameters.

另外，诸如相邻边长之比，相邻边之间的夹角等信息，由于它们不是射影不变量，所以它们对基于单幅图像的物体定位来说，提供不了任何有用的额外信息。

Suppose the harried waiter cuts the pizza off-centre, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts.

假设急匆匆的服务生是从偏离中心的位置切一块披萨的，但是所有边-到-边的切线都相交于一点，且相邻切线间的角度是相等的。

Margin attributes: the decision elements and the adjacent edge of the box elements of the distance between the edge.

margin 属性：决定元素的 box 的边和相邻元素的边的距离。

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