In fact, Computer Graphics indicate the developmental level of the Computer software and hardware, This is because Graphics have become the most important medium to transfer all kinds of information. Computer Graphics?research object is graphics, and the point , line and surface make up of the graphics ,In addition, During the real application, every graphics is made up of millions of the lines and curves, the speed and quality of the line and curve affected the implement of the whole graphics.

计算机图形学的研究对象是图形，而构成图形的几何要素就是刻画形状的点、线、面、体等，并且在具体应用中，每一幅图形都由成百上千条直线和曲线构成，这样对于每一条直线或曲线的处理速度和质量极大地影响着整幅图形的处理速度和质量，因此，对于计算机图形学基础算法的研究就具有重要意义，本文就是对计算机图形学的基础算法进行研究，包括直线和曲线的生成和裁剪算法以及基本象素的图形变换。

It not only can generate buffer zones for point, line, plane surface and compound objects, but also can generate buffer zones for the special objects with self-intersecting and containing several holes.

它解决了角平分线法的不等宽性问题，也回避了凸角圆弧法的失真现象，以统一的形式实现了缓冲区边界的自动生成。

This paper includes three parts:The first one is the comparison of VCP11 and VCP21 Recommending the Radar base data structures and reading 11 layers datas of the same elevation or so, establishing VCP22 patterns. Through the comparison of the products of two VCPs, stressing these factors, including the detecting of strong convection storm and the obvious effect products of prediction, such as ET CR VWP, RCS WER VIL SWP, etc.

本文包括3个部分：第一，新一代天气雷达两种体扫模式VCP11和VCP21的比较介绍了两种模式VCP11和VCP21基数据的数据结构，从其结构着手，读取VCP11中与VCP21模式仰角相同或者相差不大的共11层的数据，建立了VCP22模式，再由VCP11及VCP22模式的基数据生成的产品进行对比研究，重点比较了对强对流风暴探测和预报起较大影响的产品如回波顶高，VAD风廓线，垂直液态水含量，反射率垂直剖面，冰雹指数，组合反射率，弱回波区等。

The characteristic length of the products was 60 nm and the diameter of them is about 2-5 nm. By the comparative experiments, it could be concluded that the multiporous structure of AAO was the key reason for synthesizing boehmite nanowires by this method.

分析了反应过程及水热反应温度和时间对勃姆石纳米线形貌的影响，并通过对比实验表明AAO模板的纳米多孔结构是水热反应生成勃姆石纳米结构的必要条件和主要原因。
