1、 对一个等边三角形，每条边按照Koch曲线的方式进行迭代，产生的分形图称为Koch雪花。编制程序绘制出它的图形，并计算Koch雪花的面积，以及它的分形维数。
2、 自己构造生成元（要有创意），按照图形迭代的方式产生分形图，用计算机编制程序绘制出它的图形，并计算其分形维数。主要用MATLAB编程
-1, for an equilateral triangle, each side in accordance with Koch curve iterative manner, the resulting figure is called Koch snowflake fractal. Programmed to map out its graphics, and calculate the area of Koch snowflake, and its fractal dimension.
2, construct their own generators (the need for creativity), according to the way graphics iterative produce fractal images, using a computer programmed to map out its graphics, and calculate its fractal dimension.using MATLAB

本“网上考试系统”是为了配合网上教学，实现网络学校一体化而设计的。设计本系统要熟悉掌握数据库的编辑和应用，并能与网络相结合。
本“网上考试系统”是基于微软的FrontPage和Access数据库来实现的。主要采用HTML语言来编写，设计过程中还应用到ASP语言。全文共分为系统分析、系统概述、设计过程、用户说明、 结束语、参考文献。本文详细阐述了系统分析、系统设计的方法及其内容，对如何使用ASP开发本系统作了较为详细的介绍。本系统以网页的方式对数据库进行调用，系统应用简单明了，考生可以轻松查看数据库，操作员也可以对数据库进行添加、删除、修改等操作。
关键词:网上考试系统，数据库，网页语言

ST7787 芯片的SPEC，比亚迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial
Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display
data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to
minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal,
it is possible to make a display system with the fewest components.-ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD.

本文的核心linux2.6.6新特点的基础上探讨了…
本文首先分析Linux2.6.6内核新特性的基础,探讨对Linux进行实时化和嵌入式化,即通过配置内核,裁减shell和嵌入式C库对系统定制,使整个系统能够存放到容量较小的FLASH中。然后简单介绍了防火墙的概念,深入地分析了Linux2.6.6版新型内核防火墙netfilter框架的工作机制及其实现的方式。-In this paper, the kernel Linux2.6.6 the basis of new features to explore on the Linux and embedded real-time, that is by configuring the kernel, the reduction of shell and embedded C library on the system customization, so that the entire system to the capacity to store more FLASH in the small. And then briefly introduced the concept of a firewall, in-depth analysis of the new kernel version Linux2.6.6 firewall netfilter framework of the working mechanism and its implementation approach.
