中心轴

Since polar organic crystals have noncentric structures, the existence of polar axis in the crystals has a significant effect on the molecular arrangement and on the crystal growth.

极性有机晶体在不同的溶剂中具有明显不同的生长习性，主要有两个方面的原因：一是极性有机晶体属非中心对称性晶类，晶体具有极轴，极轴的存在对分子堆积和晶体生长具有重要影响；另一是极性有机晶体的界面结构不同，溶剂与晶体界面的相互作用不同，使得晶体同一面族的生长速率不同，从而导致了晶体习性的改变。

我们还特别设计了旋转培养装置，通过微型马达驱动，减速装置作用使旋转部分绕自身中心水平轴做缓慢转动，从而使置于旋转部件上的管形支架绕其正中长轴作缓慢旋转，其原理与美国 Genzrpe公司的 RCCS（Rotary cell culture system RCCS）系统相仿。

Figure 2 shows a sample spectral mask, 47 CFR 90.210 G, with a normalized X axis to show the offset from the center of the channel and a normalized Y axis to show the unmodulated carrier output.

图2显示一个频谱遮罩的例子，47 CFR 90.210 G，X轴显示距信道中心的偏移量，Y轴显示未调制的载波输出。

The axes have been drawn on for clarity, but the pivot point of the object is its actual center in X and Z, with the Y set to the base of the object.

轴已经被清楚的标上了，但是物体的轴心是其在基于物体设置的X、Y、Z轴的实际中心。

MIRDC is engaged in the research to develop the coin type blushless motor since 2005. Additionally MIRDC collaborates with Motor Center of National Cheng Kung University to develop the coin type motor under the considerations of basic motor theories and mass production technology.

本研究与成功大学马达中心合作，自基础学理出发，并纳入量产技术的考量，并在94、95年度，分别成功地开发出采用轴向气隙、轴向磁通设计的ψ17mm x t3mm、ψ15mm x t2.5mm扁薄型直流无刷马达。96年度的研发重点在突破国际现有技术水准，预定开发出ψ12mm x t2.5mm的直流无刷扁薄型马达。

Observation using transmission electron microscopy found the irreversible centripetal movement of chloroplasts in chlorotic plants, as a result occurred in three sequential events:(1) chloroplast positions changed from face position (with long axis of chloroplasts at the cell walls perpendicular to light ray) to profile position (with long axis chloroplasts near the cell walls parallel to light ray),(2) chloroplast shapes changed from long elliptical to circular,(3) chloroplasts were separated from the cell wall and moved to the center of the cell.

透射电镜观察发现失绿叶片中的叶绿体发生不可逆的向心运动，整个过程大致经历以下几个阶段：(1)叶绿体从叶绿体长轴垂直于光线转变至叶绿体长轴平行于光线；(2)叶绿体的形状从椭圆形转变为圆形；(3)叶绿体脱离细胞壁向细胞中心运动。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
