This kind of gratings can be kept in the material for a long time. A mode of molecular reorientation was used to explain the formation mechanism of these gratings and it is well consistent with our experimental results. 3. Three kinds of azobenzene polymers P , P (MMA-co-GY7) and P (MMA-co-GO13) were synthesized by radical polymerization. High-density optical storage and the three-dimension (3D) microstructures in the azobenzene polymer films were presented. Twenty gratings have been stored on the same spot in our material. It is twice as many as the best recording that has been reported. It is the first time, a rectangular microstructure and a complicated double layers nesting six-pointed star microstructure are inscribed in it by using a simple two-wave couple setup.

采用共聚反应设计合成了单偶氮苯聚合物P、双偶氮苯聚合物P（MMA-co-GY7）和P（MMA-co-GO13）三种聚合物，研究了偶氮苯聚合物薄膜中的高密度光学存储和3维微结构，成功的将20套光栅储存在样品中同一个点上，是已有报道的两倍；并首次用简单的2波混频光路在该材料中刻写出长方格子和六角星型的微结构，在制作多重不同周期不同角度的高密度光栅结构实验过程中，发现不同周期光栅的刻写顺序对整个微结构形成的最终结果具有决定性的影响，并用相衬显微镜观察了这些微结构图像。

So firstly, the flow rules of the plastic shear strain are studied in the frame of the conventional plastic potential theory.

研究发现，在角点奇异性屈服面的非平滑处理方法中，最终推导出的塑性剪应变出现不连续现象。

Secondly an offsetting for edge rings is proposed and some problems such as "region connected by point","sharp-angled ring" and "self- intersect" are solved.Then the STL data of characteristic regions are extracted.

提出了一种对边界线环进行偏置的算法，解决了偏置过程中的&点连通&、&尖角&以及&自相交&问题，实现了特征区域的STL数据的提取。

The fitting curve interpolates the corners and approximates other points in the sense of least-square.

该算法通过插值角点逼近其余数据点得到拟合曲线，更适合实际碎片轮廓的情形。

The results showed that the muscle weight of botulinum toxin injection side decreased. The craniofacial morphology of the botulinum toxin injection side were smaller in distances of zygomatic arch to mandibular lower border and ramus height than that of the normal saline injection side.

结果发现实验组大白鼠施打肉毒杆菌神经毒素侧其咬肌重量较施打生理食盐水侧及对照组小，其颅颜骨型态在颧骨弓至下颚骨缘距离，冠状突切迹最前端至下颚骨角状突最下点距离，均小於生理食盐水侧距离，有统计上之差异。

A pointed arch; usually has a joint at the apex.
