Abbe's sine condition

From Joseph Fraunhofer to Ernst Abbe on the Role of Innovative Talent;

从夫琅和费和阿贝看创新人才的作用

The results indicated a set of high refractive index glasses could be obtained by introduction of BaO and TiO_2,and the density,refractive index,Abbe number and transmission of the glass with various BaO/TiO_2 ratio based on the content of SiO_2 in 15%,12%,10%(in mass) were measured respectively.

测试玻璃的密度、折射率、阿贝数和紫外到红外波段的透过率等物化性质,研究密度和折射率与组成的关系及影响阿贝数、透过率大小的因素。

Let G be a finite Abelian group,an ideal in the grouping Zpr is called an Abelian code over Zpr.

设G为有限阿贝尔群,群环Zpr[G]中的理想称为Zpr上的阿贝尔码。

The security~ of these cryptosystems is based on the dificulty in solving descrete logarithms with Abelian group.

本文讨论了一些公钥密码体制 (ElGamal加密与解密算法、Diffie -Hellman密钥交换方案和Shamir协议 )在阿贝尔群上的扩展 ,它们的安全性均建立在阿贝尔群上离散对数求解困难性的基础之

The ellipse rotating symmetric group is proposed,which is an Abelian group.

提出椭圆旋转对称群,它是一个单参数阿贝尔群。

The AFM head is mounted without Abbe error in the X and Y directions.

原子力测头的布置在X、Y方向无阿贝误差。

Theorial study and calculation show that Abbe error can be decreased to almost zero by use of the structure and it can meet the demand of nano-platform.

经理论研究计算,能实现近零阿贝误差,满足微纳米级定位平台的要求。
