OpenCV是Intel® 开源计算机视觉库。它由一系列 C 函数和少量 C++ 类构成，实现了图像处理和计算机视觉方面的很多通用算法。 重要特性 OpenCV 拥有包括 300 多个C函数的跨平台的中、高层 API。它不依赖于其它的外部库――尽管也可以使用某些外部库。 OpenCV 对非商业应用和商业应用都是免费（FREE）的。（细节参考 license）。 OpenCV 为Intel® Integrated Performance Primitives (IPP) 提供了透明接口。 -OpenCV

本程序根据Jean Meeus的《天文算法》一书中给出的算法，实现对太阳天顶角和方位角的计算，有效时间范围和精度分别为：-2000-6000年，±0.0003 度。 程序作者Ibrahim Reda and Afshin Andreas,由National Renewable Energy Laboratory提供。-This program is a step by step procedure for implementing an algorithm to calculate the solar zenith and azimuth angles in the period from the year-2000 to 6000, with uncertainties of ±0.0003 degree. The algorithm is described in a book written by Jean Meeus in 1998.

摘　要　虽然开放系统是一个流行的名词, 但是对于一般用户, 它却是一个在实际工作中“无法操作”的事物。本文从计算机开放系统的基本特征出发, 通过逻辑推理, 导出描述开放系统的轮廓, 借助于后者使开放系统一词的内涵得到了澄清, 并使它的实现变成了“可操作的”。文中还从IT 实际工作的方便出发, 提出了一个简明的开放系统的工作定义。关键词　开放系统, 轮廓, 可移植性, 可互操作性, 封闭系统, 开放式专有系统-Abstract Although open systems is a popular term, but for the average user, it is a practical work in a "inoperative" things. This open computer systems from the basic characteristics, through logical reasoning, derived describing the contours of open systems, using open systems which enable the connotation the word has been clarified, and the realization that it has become a "workable." The article also from IT to facilitate the practical work, put forward a simple one, the open system of working definition. Keywords open systems, contour, portability, interoperability, closed system, an open-end proprietary systems
