查询词典 rings

It will consist of two " superconducting magnetic channels" or "rings" housed in the same yoke and cryostat, a unique configuration that not only saves space but also gives a 25 % cost saving over separate rings!

Prange first began to study cyclic codes over finite field in 1957 and Berkelamp first began to investigate negacyclic codes over finite field in 1968,but the codes over finite rings didnt received much attention until the 1990s due to the works of Nechaev in 1991 and Hammons in 1994,which showed that well-known nonlinear codes such as Kerdock and Preparata codes are constructed from linear codes over finite rings.

Prange(1957)和Berkelamp(1968)分别首先开始研究有限域上的循环码和负循环码，直到上世纪90年代，Nechaev(1991)和Hammons(1994)通过有限环上的线性码构造出著名的非线性码如Kerdock码和Preparata码，有限环上的码才受到广泛关注。

As to cyclic codes over finite chain rings, we study their stucture and develop the Fourier Transform method to finite chain rings. The permutation groups of cyclic codes and their extended codes are investigated using their Mattson-Solomn polynomials.

对于有限链环上的循环码，我们研究了它们的结构，并把傅立叶变换的方法推广到有限链环，用循环码的Mattson-Solomn多项式对循环码及其扩展码的置换群进行了研究。

The results show that:Changing the substituents of the phenyl rings,on the one hand,will influence the capacity of conjugation of the phenyl rings through S→N dative bond and furthermore influence the weak acid-dissociation of phenolic hydroxyl,on the other hand,will influence the geometric conformation of the compound and furthermore influence to form structure matched with membrane and water/membrane.

结果表明：改变药物化合物两边苯环上的取代基，一方面，将影响苯环通过S←N授受键的共轭能力，进一步影响酚羟基的弱酸离解常数；另一方面，将影响C-S，S-N键自由旋转的难易程度，进一步影响到能否形成与膜/水膜界面相匹配的结构。

The Fresnel lens, also known as the dioptric lens, consists of a central glass disk and concentric glass rings or a central glass band surrounded by parallel glass rings.

一个在中心的玻璃圆片和与之同圆心的层层玻璃圆环，或者中间是一个玻璃带，两边是与之平行的玻璃带状环。

In section one, we study regular cu-rings by use of full elements in rings, and give some equivalent conditions for the endomorphism ring of quasi-projective modules and quasi-injective modules to be a cu-ring.

在第一部分，我们利用环中的完全元对正则cu-环进行刻画，并给出了拟投射模和拟内射模的自同态环是cu-环的一系列等价条件。

This Handbook deals with the foundations of incidence geometry, in relationship with division rings, rings, algebras, lattices, groups, topology, graphs, logic and its autonomous development from various viewpoints.

这本手册涉及发生几何学的基础，在有划分戒指，戒指，代数，格子，组，拓扑，图，来自各种各样的观点的逻辑学和它的自治发展的关系里。

另外，证明有限域上一般线性群的C_1类极大子群和特殊线性群的根子群的不变式环是多项式的。

The method includes identifying (101) a surface in the image, and for each point in the image, calculating (102) a first curvature measure, forming (103) a set of rings of points about each point, each ring being of equal geodesic distance from a center point for the ring, calculating (104), for each ring, a standard deviation of the first curvature measure, and selecting (105) those rings with a minimum standard deviation for the first curvature measure.

该方法包括在所述图像中识别(101)表面；为该表面中的每个点计算(102)第一曲率量；为该表面中的每个点形成(103)围绕每个点的一组点环，每个环具有到该环的中心点的相等的测地距；为每个环计算(104)第一曲率量的标准偏差；以及选择(105)那些具有第一曲率量的最小标准偏差的环。
