有环的

According to algebraic number theory,all solutions of Pocklington equation in a ring of integers of a quadratic imaginary field are determined,which implies that the equation has only several solutions in the ring.

利用代数数论的理论与方法，决定了一个重要的不定方程在一个特殊的虚二次域整数环中的解，从而指出这个方程在比整数环更大的环中也仅有有限个解。

The structure is formed by the assemblage of the second building units: cancrinite cage, according to the hexagonal space groups P63/mmc. It has not only the 18-ring pore channel system which parallels to the c-axis as in VPI-5, but also 10-ring pore channel system along both a and b-axis. The results obtained from calculating the bond distances and angles between the...

与VPI-5类似，具有平行于c方向的十八元环直孔道结构，但侧面有十元环孔道，通过计算该结构模型各原子间的键长、键角，认为该结构有可能存在，采用POWD-MODELING程序，计算了它的理论XRD谱图并绘制出其立体拓扑结构。

There are three principal types of system, Closed Loop, Open Loop and Hybrid Systems.

有三种主要类型的系统，闭环，开环和混合系统。

We give a theorem for the stable range of endomorphism rings of finitely generated projective modules over a formal triangular matrix ring T when T is an exchange ring.

2.6节对有有限exchange性质的形式三角矩阵环T给出了有限生成投射T-模的自同态环有稳定度n的一个具体关系。

First of all, to brief Members on the new map location, location is Hemosiderosis Troll magic stone city of brush, where there is a lot of doors, the doors, there is a magic ring, click the magic ring will be able to enter a new map.

首先给大家介绍一下新地图的位置，位置在于铁血魔城刷投石巨魔的地方，那里有一个很大的门，门上有一个魔环，点击魔环就可以进入新地图了。

Moreover, the equivalance between regularity of a ring and a full matrix ring is proved with a new method.

当 R是一个有单位元的环时，本文引进并刻划了Mm× n的正则性并由此重新证明了环 R与全矩阵环 Mn正则的等价性，这种方法比原有的证明方法简

Its action is different from the Central Materials, 60A and 60C of the actin ring are made of cemented carbide YG6, and 60B of the fixed ring, the matrix material for oCrl8N112M02Ti, sealed in its side surface with a layer of surfacing thickness 1.5mm the hard alloy.

其动环材料有所不同，60A和60C的动环都是由硬质合金YG6制成的，而60B的动环，其基体材质为oCrl8N112M02Ti，在其密封端面上堆焊有一层厚度为1.5mm的硬质合金。

Lining papers is a slip sheet between cover and the book core , painting also has a picture on many lining papers drawing capital , only, you may be sure not to believe they are patterns playing decoration role only but one turns over immediately but live with, in fact, draw this lining papers being closely linked with the text story not only , return the lifting subject back to a meeting sometimes.

环衬是封面与书芯之间的一张衬纸，很多绘本的环衬上也画有图画，不过你可千万不要以为它们仅仅是起装饰作用的图案而马上一翻而过，实际上，绘本的环衬不但与正文的故事息息相关，有时还会提升主题。

The motion control problems of uncertain robots is studied in this paper The main work consists of six parts 1 A novel robust outer-loop design method is proposed for the robot manipulators with constructed and unconstructed uncertainty The global convergence of the closed-loop system and the uniformly ultimate boundedness of tracking error when the continuous control law is used are proven The proposed method has better accuracy than the existing method.

本文研究具有不确定性的机器人的运动控制问题，主要工作由六部分组成：一、对具有结构型和非结构型不确定性的机器人提出了一种新的鲁棒外环设计方法，闭环系统的全局收敛性和连续化鲁棒控制器的终结有界性得到了证明，比已有方法有更好的跟踪精度。
