According to the basic principles of information theory, computer graph processing and the chromatics, this thesis mainly researches on the theory and applications of the color images watermark using the characteristics of the human visual system.

本文首先根据信息论、计算机图形处理和色彩学中的基本原理，结合人眼的视觉系统特性，对彩色图像水印的理论与应用进行了研究，然后讨论了如何对水印图像进行反色和置乱预处理，尤其是对水印嵌入过程、水印提取过程和水印攻击方法等进行了深入探讨，并最终设计实现了1套完整的具有水印嵌入与提取功能的实验软件。

According to the basic principles of information theory, computer graph processing and the chromatics, this thesis mainly researches on the theory and applications of the color images watermark using the characteristics of the human visual system. And then it discusses the preprocessing method such as Image color inversing and image disordering, especially the method of watermark embedding, watermark extracting and watermark attacking etc. At last, an experimental system about watermark embedding and extracting are accomplished.

A new method based on the digital chromatology to detect the concentration of colored transparent solution was developed and the associated system was established.

提出基于数字色度学的有色透明溶液浓度快速检测方法，并开发了配套的检测系统。

The forest was characterized with phanerophyte evergreen plants with single-mesophyll-leathery leaves, which reflected the nature of tropical Karst mountainous seasonal rain forest.(2). Community succession was divided into five stages by using Cluster method, PCA method; the succesion stages include herbaceous stage, scrub-shrub stage, small tree stage, arbor stage and climax seasonal rain forest stage.(3). Based on similarity theory, succession sere was constructed with the community similarity equation formed.

结果表明：(1)森林群落在外貌上，以常绿高位芽、单叶、革质、中型叶植物为主，反映了热带岩溶山地季雨林的特点；(2)运用聚类分析、PCA排序等方法将群落演替阶段划分为草本群落阶段、灌丛阶段、小乔木阶段、乔林阶段、顶极季雨林阶段；(3)运用相似学原理，组建群落间相似度方程并以此方程构建了群落演替系列；(4)研究表明桂西南岩溶区生态系统健康受到严重胁迫。

The graph cliping algorithm is the basis of computer graphics algorithms.The graph cliping algorithm is good or not directly influence entire graphics system's performance.

图形裁剪算法是计算机图形学的基础算法，图形裁剪算法的好坏，直接影响到整个图形系统的性能。

Acquired WIN95 system to be stupefied simply later, see colorific thing eventually.

后来学到WIN95系统简直惊呆了，终于看到色彩的东西。

The result of Industrial Cooperation Project with 「HUAN CHENG e-Logistics Inc.」 is presented in this paper. This research primary utilization combinatory logic for electric circuit design concept, matching infrared system and Electronic Weighing Scale System as sensor, after two sensors are all triggers, it may choose whether starts a defense mechanism, achieves the initiative defense to protect mercantile firm、supermarket and public place.

本研究是与「寰成物流股份有限公司」之产学合作计画之成果，该研究主要运用组合逻辑电路的设计概念，搭配红外线系统及电子磅秤作为感测，当两个感测机制都触发后，可选择是否启动一个防卫机制，以达到主动防卫受保护之店家、超商、公共场所的安全。

Before discussing Xing Yunlu's calendrical work, we reviewed the calendrical system of the Ming Dynasty and the status of the calendar crisis and the endeavor of reviving the traditional calendar made by the scholars Gu Yingxiang (1483-1565), Tang Shunzhi (1507-1560) and Zhou Shuxue (?1500-?1572) during the Emperor Jia Jing (1522-1566) in the Ming Dynasty. These scholars had paid attention to the underlying mathematical principles of Shoushi Computus, especially the method on arc and arrow in the geometry.

在讨论邢云路的改历活动之前，首先对明代的历法系统以及传统历法出现危机的状况以及明代嘉靖年间顾应祥(1483-1565)、唐顺之(1507-1560)、周述学(约1500-约1572)等复兴传统历法的努力进行讨论，指出：明代嘉靖年间学者的改历理念主要是注重讨论被钦天监历官忽视的《授时历》的立法原理问题，并对《授时历》弧矢术做了一些有益的探求工作。

Information retrieval learned to provide a solid basis for us, on this foundation we apply most structure of constant visit link, webpage and other innovation technology built a huge system.
