MySQL是一个精巧的SQL数据库管理系统,虽然它不是开放源代码的产品,但在某些情况下你可以自由使用。由于它的强大功能、灵活性、丰富的应用编程接口(API)以及精巧的系统结构,受到了广大自由软件爱好者甚至是商业软件用户的青睐,特别是与Apache和PHP/PERL结合,为建立基于数据库的动态网站提供了强大动力。
MySQL有瑞典的T.c.X公司负责开发和维护,MySQL的用户手册很单纯,只有一个集中的,但其内容覆盖了MySQL的所有信息,因此该手册是了解和掌握MySQL的绝佳文献。
虽然对MySQL的开发不能出一份力,但可为它的推广使用尽一份心,面对500多页的参考手册,知道要精确译出它决非易事,但愿几个月的心血能为大家提供一丝微薄的帮助。
由于本人水平有限,文中肯定有不准确的地方,敬请在阅读过程中不吝指出。文中不明之处,请参阅手册原文。
本文的内容针对MySQL 3.23.7alpla,实际上很多内容是通用的。另外,参考手册的几个附录也是很有价值的,但由于时间有限,未能译出,可参见原文。-MySQL is a sophisticated SQL database management systems, While it is not open source products, but in some cases you can freely use. Because of its strong capabilities, flexibility, rich application programming interface (API) and the elegance of the structure, by the vast number of free software enthusiasts even commercial software users favored especially with Apache and PHP/PERL combination for the establishment of the dynamic database-based web site provided a powerful impetus.

说明: 要研究一个新的重建算法-迭代软阈值算法,该算法根据所要解决的问题而确定一个阈值函数,并且可以将阈值算法和迭代算法有效的结合使用,明显的提高了重建信号的精度。本文主要对语音信号和带噪语音信号分别进行信号重建性能分析和研究。包括信号的稀疏性表示、观测矩阵的设计和选择、信号的重建过程及效果,通过实验仿真的波形图,进而对其和原语音信号不同之处进行了分析与对比。(To study a new reconstruction algorithm iterative soft threshold algorithm, this algorithm determines a threshold function according to the problem to be solved, and can effectively combine the threshold algorithm and iterative algorithm, which significantly improves the accuracy of reconstruction signal. In this paper, the performance of speech signal reconstruction is analyzed and studied. It includes the sparse representation of signal, the design and selection of observation matrix, the reconstruction process and effect of signal. Through the waveform of experimental simulation, it analyzes and compares its differences with the original voice signal.)
