The acidity of HZSM-5 was due to the non-framework aluminum species, i.e., SiAl. The intensity of acid sites of HZSM-5 declined while the quantity of acid sites increased with dehydration temperature, with optimal intensity and quantity of acid sites and maximum toluene conversion of 28.2% at dehydration temperature of 400℃.

HZSM-5分子筛的酸性变化主要是由于非骨架铝物种SiAl的变化而引起，随着脱水温度的升高，HZSM-5分子筛酸中心的强度下降，但酸中心数量增加，当脱水温度为400℃时，HZSM-5分子筛的酸中心强度和数量达到最佳，甲苯转化率为28.2%。

The hydrothermal synthesis of small crystal silicious ZSM-5 zeolite in the presence of cheap template was studied in this paper.

ZSM-5沸石是一种极其重要的分子筛催化材料。通过调节骨架硅铝比和晶体粒度可以有效地调节ZSM-5沸石的催化性能。

The cis-decalin 79 was obtained from 2-methoxy-4-methylphenol (77) via a sequence of reactions involving intermolecular Diels-Alder reaction of masked o-benzoquinone derived from 77 and ethyl vinyl ketone, silyl enol ether formation and Cope rearrangement.

第一部份：以2-甲氧基-4-甲基酚(77)为起始物，经由二乙醯基亚碘苯氧化、分子间Diels-Alder反应、烯醇矽醚的形成及Cope重排反应得到具有十氢萘骨架化合物79。

We've provided a MyCug 'skeleton' class in the Skel

The second part is its application to Chinese character skeletonization .

本文的工作主要分为两个部分，第一部分提出了一种自适应的简明主曲线算法，第二部分给出了主曲线在汉字骨架提取中的应用。

The system consists of five individual steps:Data Acquisition, Image Enhancement, Vein Pattern Segmentation, Skeletonization and Matching.

该系统由五个单独的步骤：数据采集，图像增强，静脉格局分割，骨架和匹配。

Image Enhancement, Vein Pattern Segmentation, Skeletonization

图像增强，静脉格局分割，骨架

Many skeletonization approaches have been proposed, try solving the defects that are intrinsic in traditional thinning algorithm, however, almost all approaches produce extra distortions; moreover, these approaches are usually applicable to some specific font only.

虽然许多的骨架化方法已被提出，试著克服传统细化的缺点，但这些方法几乎都会产生额外的失真，而且，这些方法通常只适用於某特定的字型。

The robustness is obtained thanks to the fact that some local mismatches in the approach are generally impossible to change the global correct matching trend The method can not only be used for sectional images matching in medical field as it did in the thesis, but can also be used in other fields, such as stereo vision [2] Distance transformation plays quite an important role in object thinning and skeletonization in image processing.

2〗距离变换是一种基本的图象处理工具，它在实现目标细化、骨架抽取等方面起到重要作用。作者提出了一种统一化的距离变换，它能够快速实现多种距离测度的距离变换。当进行欧氏距离变换时，其平均误差远远小于文献中现有的方法，并且出现误差的概率也大大地降低了。

Distance transformation is a global operation on binary image which is widely used in skeletonization, shape matching, object reconstructing, obstacles elusion, etc.

距离变换是一种基于二值图像的全局操作，在骨架抽取、形状匹配、目标重建、机器人避障等图像分析与模式识别算法中有着广泛的应用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
