查询词典 rings

At last,we give the definition of FGT rings which is the extension of cogenerator rings.

在第二章中，我们由FGT -内射模的启发引入了CT -内射模的概念，在这一章我们知道ann -自内射环其实就是CT -内射环，只是ann -自内射环是从零化子的角度来讨论，而CT -内射是从循环无挠模的角度来进行讨论的，同时也给出了一些等价条件。

Commuta-tivity is one of important properties on rings. Study of commutativity is beneficial to discussion of other properties on rings.

同时，交换代数本质上是研究交换环的，这就使得环的交换性的研究变得很重要。

R plays an important role in constructingnew classes of rings, getting counter example in ring theory and characterizing the relationships between different rings.

的子环。R在构造新的环类，给出环论中的反例，以及刻画环与环之间的关系方面起着重要的作用。

The honed crosshatch pattern in the cylinder bore acts like a file to allow the rings to wear. The rings quickly wear down the "peaks" of this roughness, regardless of how hard the engine is run.

被珩磨成刀路相互交叉的油缸内孔像一把锉刀去摩擦密封环，密封环很快就将各高点磨掉，这与狠用发动机没有关系。

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!

它将会包括被包裹在同一个套子和低温保持器里边的两套超导磁铁隧道。这种独特的构造不但节省空间，而且帮我们节约了经费的25%！

Pearl rings, especially cultured pearl rings, are beautiful gifts that can be cherished for generations.

珍珠戒指，特别是养殖珍珠戒指，是美丽的礼物，可以珍惜几代人。

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。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
