To the problem that the isotropy and the technological efficiency of the parallel kinematic machine based on Stewart platform are not satisfactory, a novel architecture of 6-DOF 3-dimensional platform parallel kinematic machine (6-DOF 3-D PPKM) based on the 2-2-2-SPS 3-D PPR is presented. The technological efficiency of design of the parallel kinematic machine is analyzed. Its workspace and the effect of design parameters to the workspace volume are studied. By using the submatrices of Jacobian matrix and force Jacobian matrix, the kinematics/mechanics transmission isotropic indices, kinematics transmission indices, load-bearing capacity indices at any configuration of the parallel kinematic machine are proposed, respectively.

The matrix representation of GLKC is given on the basis of topological characteristics of GLKC, so the problem of the mathematical description is solved successfully for the type synthesis of GLKC.

进而分析了GLKC的结构不变量，根据这些结构不变量，给出了GLKC同构判定的一般方法，即利用组合矩阵的幂序列成功地解决了GLKC的同构判定问题。

In the same night one cannot visit the morgue, the infirmary, the zoo, the signs of the zodiac, the limbos of philosophy , the caves of epistemology, the arcana of Freud and Stekel… On the merry go round one doesn't get anywhere, whereas with the Germans one can go from Vega to Lope de Vega, all in one night, and come away as foolish as Parsifal.

一夜之间一个人不可能遍访陈尸所、疗养院、动物园、十二宫、哲学之困境、认识论之洞穴、弗洛伊德和司大克的奥秘……骑在一匹孩子们玩的旋转木马上，一个人哪儿也去不了，而同德国人在一起你便可以在一夜之间从织女星来到维加面前，而离去时仍同帕西发尔一样蠢。

Metamerism phenomenon to color business card printing and membership card making adverse effects, and therefore the business card printing and membership card bearing in mind that join in making control.

同色同谱本体给不黑白制卡和会员卡制作带来倒霉的感化，因此在制卡和会员卡制作洋给夺目参加把持。

A one color in a color of the light source under the same, but in a separate light sources, their rendering of color change in the phenomenon is called metamerism.

这种当一种颜色在某光源下表现的颜色不同，但在另外的光源下，其表现的颜色爆发保持的本体不离称为同色同谱本体。

In addition, metamerism ink is the newly developed special inks, the ink business card printing and membership card, produced in different light exposure to or change the direction of light, you can produce different graphics and text color.

此外，同色同谱油墨也是陈研制斥地的出格防伪油墨，诳骗这种油墨制卡和会员卡制作的图文，在差别光源照射下或保持光芒标的目的，不离可以爆发差别的图文颜色。

The method is based on the preliminary reaction of a part of OH cellulosic groups with the methacrylic chloride of the unsaturated acid.

先将纤维素的部分羟基同甲基丙烯酰氯反应，然后将丙烯腈同上述改性纤维素进行接枝反应。

In order to study vector-valued optimization problem, in chapter 5, a class of vector -valued function, that is, uniformly same-order set-valued function is introduced , which includes the separated functions as its proper subset; without hypothesis of convexity, new minimax theorem and saddle point theorem for uniformly same-order set-valued function are established. Next, by employing Ky Fan\'s lemma and H-KKM mapping , several existence results for generalized vector equilibrium problem established.

为了研究向量优化问题，作为可分函数的推广，第五章引入了一致同阶集值函数类，在没有凸性条件的假设下，对一致同阶集值函数建立了新的极小极大定理与鞍点存在定理；利用H-KKM映射，对一般向量均衡问题建立了(来源：A73BcbC论文网www.abclunwen.com)几个存在性定理；最后讨论了集值向量均衡问题系统，利用集值映射的拟凸性，在较弱的条件下证明了解的存在性。

I have a dream that one day in Minster, the sons of former slaves and the sons of former slaveowners will be able to sit down together at a table of brotherhood.

我梦想有一天，在明斯克，昔日奴隶的儿子能够同昔日奴隶主的儿子同席而坐，亲如手足。

We may make poor decisions on the basis of what we know, we often fail to communicate our knowledge to others, and we may misrepresent our knowledge or lack of it when dealing with others.

依据我们所知道的知识来做的决定可能会是糟糕的决定，通常我们不能把我们知道的知识同别人很好的交流，同别人交流时我们可能没有正确的表述我们的知识或者对这一知识本来就缺乏。

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。
