java软件开发-顶岗实习周记25篇(20211215114851).pdf

This book is an introduction to computer graphics with an emphasis on applica- tions programming. The first edition, which was published in 1997, was somewhat revolutionary in using OpenGL and a top-down approach. Over the succeeding 16 years and 6 editions, this approach has been adopted by most introductory classes in computer graphics and by virtually all the competing textbooks. The sixth edition reflected the recent major changes in graphics software due to major changes in graphics hardware. In particular, the sixth edition was fully shaderbased, enabling readers to create applications that could fully exploit the capabilities of modern GPUs. We noted that these changes are also part of OpenGL ES 2.0, which is being used to develop applications for embedded systems and handheld devices, such as cell phones and tablets, and of WebGL, its JavaScript implementation. At the time, we did not anticipate the extraordinary interest in WebGL that began as soon as web browsers became available that support WebGL through HTML5. As we continued to write our books, teach our SIGGRAPH courses, and pursue other graphics-related activities, we became aware of the growing excitement about WebGL. WebGL applications were running everywhere, including on some of the latest smart phones, and even though WebGL lacks some of the advanced features of the latest versions of OpenGL, the ability to integrate it with HTML5 opened up a wealth of new application areas. As an added benefit, we found it much better suited than desktop OpenGL for teaching computer graphics. Consequently, we decided to do a seventh edition that uses WebGL exclusively. We believe that this edition is every bit as revolutionary as any of the previous editions.

为解决油层部分射开、顶底封闭、各向异性的三重介质油藏不稳定渗流问题，采用点源、线源的思想，得到无限大三维油藏中的连续点源解；使用镜像反映法及Poisson求和公式，得到顶底封闭时的连续点源解，沿射开层段积分，得到油藏不稳定渗流的均匀流线源解；根据有效平均压力点理论，得到无限导流线源解；利用Stehfest数值反演和程序设计绘制典型曲线，并根据渗流机理，分析影响曲线形态特征的因素，如储容比、窜流系数、射开程度、垂向各向异性系数等．结果表明：该方法有助于认识此类复杂油藏的渗流机理，也可用于试井分析、油藏产能研

1.引言     随着电子信息对抗系统、雷达系统、武器控制系统、指挥决策系统、通讯导航系统的发展与升级换代，在有限的频谱范围内，工作频率的高度密集甚至是重叠、单位体积内电磁功率密度的迅速增加、各种电子设备的电磁干扰和敏感度的不断提高。特别是作为对电磁环境有重大影响的载体上的天线，其类型与数量存在着增加的趋势。平台上的天线少则几部，多则十几部几十部，有的甚至达到天线林立的程度。这些状况造成载体内部及其周围空间的电磁环境越来越复杂，从而导致电磁兼容的问题日益突出。作为直接影响和制约系统电磁兼容性的天线，其电磁兼容问题，包括理论分析预测、设计技术和试验调试等自然成为关注的问题。     本文采用
