In this paper we study the effect of numerical integration in expanded mixed finite element methods for linear elliptic problems.

关于数值积分对椭圆型及抛物型方程有限元方法的影响，已有一些研究，本文考虑了数值积分对扩展混合有限元方法的影响。

Then it is also proved that J is retractable to a∈R+ on Γε by the ordinary differential equation ...

从而得到了奇异椭圆方程的边值问题至少存在一个正解的结论。

The hyperbolic grid generation method which doesn't need to determine the outer boundary of the embedied grid in the Chimera grid and is well controllable for the density of the grid is studied and developed, and in this method the Laplace's smoothing method is used to deal with local corner problem.

1在嵌套网格思想的基础上，研究和发展了嵌套网格方法中不需定义内嵌网格外边界且网格疏密可控性好的双曲型方程网格生成方法，并采用了椭圆光顺技术和当地拐角处理技术。

One of the most popular American sports, Football is a game between two sides aiming to outscore each other with the use of an oval ball.

美国最流行的体育运动之一，共有两队比赛，使用的球呈现椭圆形状，争夺分数取胜。

That's on a big, concrete, oval track.

那是在一个大型的混凝土椭圆轨道上的比赛。

Then the single layer spherical, cylindrical, elliptic paraboloidal reticulated shell and double layer cylindrical reticulated shell are calculated on the large deformation stability respectively, which show the application of the development system on the large deformation stability analysis of space bar structures.

用所开发的系统对单层球面网壳、圆柱面网壳和椭圆抛物面网壳以及双层柱面网壳进行了大变形稳定性计算，说明了所开发系统的可应用性。

A systemic research on the birefringence of side-hole fiber is presented. The research results show that the birefringence of circular-core side-hole fiber relies mainly on stress birefringence, its fast axis is parallel to the link line of the two holes, and its intrinsic birefringence increases exponentially with the angle and ellipticity of side holes.

本论文的主要研究结果和创新在于： 1、对边孔光纤的双折射特性进行了系统研究，提出圆芯型边孔光纤以应力双折射为主，两边孔连线方向为其快轴方向，其双折射大小与边孔张角和边孔椭圆度成指数关系。
