中心

The author generalized the results of the centralizer of matrix over complex number field to Real Quaternion field .

推广了数域上的矩阵中心化子理论，得到了实四元数体矩阵上的中心化子理论

So, the changing rule of the centre of a circle in benchmark section is where R2 is uniform transform matrix of the centre of a circle in middle part of robot's benchmark section; dp is unit journey.

So，一个圈子的中心的改变的规则在基准的section是 where R2是一致的变换a的中心的矩阵在robot's基准部分的中间部分的circle； dp是单位 journey。

The direction vector of benchmark in behind gasbag at the beginning position is ngr1＝nt1,the coordinate of the centre of a circle is where g is suffix, gasbag; r is suffix, the end of robot; d01 is distance of the centre of a circle between the behind gasbag benchmark section and drill mud head benchmark section.

The基准方向向量在的气囊之后 beginning位置是ngr1＝nt1，中心的座标of圈子是 where g是词尾，气囊； r是词尾，机器人的末端； d01 一个圈子的中心的is距离在后面之间的 gasbag基准部分和钻子泥朝向基准 section。

The direction vector of benchmark at the beginning position is nz1＝nt1,when the middle gasbag follows along straight line, the coordinate of the centre of a circle is where d03 is distance of the centre of a circle between the middle gasbag benchmark section and drill mud head benchmark section.

The基准方向向量首先安置 is nz1＝nt1，当中间气囊沿平直的跟随line，圈子的中心的座标是 where d03是一个圈子的中心的距离在之间的 middle气囊基准部分和钻子泥朝向 benchmark部分。

The chapter four proposes a new method to locate graph center and also a novel centric index.

第四章提出了确定分子中心的一种新的方法以及一个新的分子中心指数。

To do so, we have to know the extent of the centricity and the industry structure s.

西部大开发需要依靠中心城市的推动作用，而要发挥中心城市的作用就必须先了解其中心性的大小及其行业结构。

It has the same structure as the mature parental centriole, but is only about half its length.

它同成熟的父代中心粒有相同的结构，但仅仅是父代中心粒长度的一半。

The mass of cytoplasm surrounding the centriole in a centrosome.

中心体细胞质与细胞核相邻的一块含有中心粒的区域，用来组成微管

However, the centriole is not essential for spindle formation, although an analogous structure, the basal body, is responsible for organizing the microtubules of UNDULIPODLA.

但中心粒对于纺锤体的形成并不是必须的，尽管具有相似的结构－基体，中心粒对于波动足微管的形成有重要作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
