in the corona, consisting of an eruptive prominence and/or a magnetic flux region (loop or arcade, or blob) in front of the prominence. Ahead of the piston, there is a compressed flow, which produces a shock front. This high-density region corresponds to the bright feature of the transient. Behind the piston, there is a rarefaction region, which corresponds to the dark feature of the transient. Therefore, both the bright and dark features of the transient may be explained at the same time by the dynamical process of the moving piston.

本论文主要讲述了作为CSR控制系统信息存储和关系协调中心的CS尺数据库系统及其BLOB、信息录入等相关内容的研究、设计和实现。我们选用Oracle作为数据库平台,并使用Rose对oracle进行建模,解决复杂的表关系和大量的表结构,完成了许多CSR系统的数据库建设。开发了操作Oracle中BLOB字段的Cokl组件,解决了高速的大数据块的存储问题。采用ASP完成了CSR数据库信息录入系统,使操作人员通过网络完成各个子系统有关信息的录入。这些都已可靠、高效、方便的用于实际的控制系统中。创造胜地提出了CSR数据库软件工程,CSR数据库命名规范,CSR数据库数据字典,CSR数据库安全策略等,以及完成了CSR数据库缩写管理系统,CSR数据库字段管理系统CSR数据库表视管理系统等。这些开发规范和管理系统在实际的数据库开发中起着指导和辅助作用。

Naphthalene-labeled polypropylene (PP) was prepared by melt reaction of maleic anhydride-grafted-polypropylene (PP-g-MA) with 1-aminonaphthalene in a Barabender mixer chamber. The structure of the product was analyzed with fourier transform infrared (FT-IR), ultraviolet (UV) and fluorescence. The results showed that naphthyl groups grafted onto the PP molecular chains through the imide bonds formed between MA and 1-aminonaphthalene. The content of the chromophores was 1.8 X 10(-4) mol g(-1) measured by elemental analysis. Isothermal crystallization behavior was studied by differential scanning calorimeter (DSC). Labeled PP had a higher crystallization rate than PP-g-MA. Wide-angle X-Ray diffraction (WAXD) analysis revealed that labeled PP had higher crystallinity than PP-g-MA.

为了避免人眼对产品外观质量检测时,人眼视觉疲劳所产生的产品错检、漏检,提出了基于机器视觉的烟支条盒包装质量检测系统的设计。该系统由光源、相机、图像采集卡和工业控制计算机组成视觉系统处理单元,应用定位配准、边缘检测和斑点分析等图像处理算法完成对产品缺陷的检测。该视觉检测系统已经在烟厂得到了实际应用,对今后开发类似的基于机器视觉的产品外观质量检测系统具有一定的参考价值和指导意义。
