Now use the Elliptical Marquee tool to select the excess and cancel it.

现在使用椭圆选框工具选择多余的，并删除它。

The main focus of the thesis is the multiple point multiplication algorithm of elliptic curve cryptography.

本文主要研究椭圆曲线密码系统的多点乘算法。

In chapter III,we consider the wavelet method for the approximation of the nu-merical Bergman kernel.It is very clear that the Bergman kernel plays an importantrole in the complex analysis and elliptic equations.The Bergman kernel has a closedrelation with the Riemann mapping,Green function,Neumann kernel and the Szeg〓kernel etc.

第三章研究了数值Bergman核数值逼近的小波方法，Bergman核在复分析和椭圆型方程中占有重要地位，它与Riemann映射、Green函数、Neumann函数、核等有着密切联系。

The elliptic curve discrete logarithm of non singular elliptic curve over finite field has no efficient attack up to now, which made it cannot be widely applied in cryptography.

目前，在有限域上非奇异椭圆曲线离散对数问题还没有有效的攻击方法，使其在加密技术中得到了广泛应用。

Ex:The earth isn't a perfect sphere ; it's an oblate spheroid.

Flexible metal seal butterfly valve is the national focus on new products, high-performance flexible metal seal butterfly valve used one pair of eccentric and a special oblique cone oval seal structure.

弹性金属密封蝶阀是国家级重点新产品，高性能的弹性金属密封蝶阀采用了一个双偏心和一个特殊斜锥椭圆密封结构。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
