微电子技术、计算技术和无线通信等技术的进步，推动了低功耗多功能传感器的快速发展，使其在微小体积内能够集成信息采集、数据处理和无线通信等功能。无线传感网络(wireless sensor network, WSN)就是由大量部署在监测区域内的这类传感器节点组成，通过无线通信的方式形成的一个多跳的自组织的网络系统，从而协作的感知、采集和处理网络覆盖区域的监测信息，并发送给观察者。无线传感网络技术将是21世纪最有发展前景的技术之一。本文在介绍了无线传感网络的基础上，着重分析和研究了现有的无线传感网络的路由协议和算法。-err

本书系统深入地介绍了各种代码优化编程技术。全书分为4章。第1章集中介绍如何确定程序中消耗CPU时钟最多的热点代码的所谓程序剖析技术以及典型部分工具的实用知识。第2，3章分别全面介绍RAM了系统与高速缓存子系统的代码优化知识。第4章主要介绍了机器代码优化技术。各章在讨论基本原理的同时详细给出了代码实例，并对优化性能进行了定量的分析。该书特别适合于作为应用程序员及系统程序员的学习与开发之用。同时，本书对在硬件方面的专业人员与技术工作者有一定的参考价值。-This book system, in-depth description of the various code optimization programming. The book is divided into four chapters. Chapter 1 focus on how to determine the program consumes CPU clock up to the so-called hot code analysis techniques and procedures for a typical part of the tools and practical knowledge. Separately in Chapter 2,3 introduced the first comprehensive system RAM and high-speed cache memory subsystem, the code and optimize their knowledge. Chapter 4 focuses on the machine code optimization techniques. In discussing the various chapters, while the basic principles of the code examples are given in detail, and optimize the performance of the quantitative analysis. Book is particularly suitable as an application programmer and system programmer le

用VC制作带弹出式菜单的按钮 带有弹出式菜单的按钮可以使一个按钮具有多项选择功能，扩展了按钮的功能，相当于把多个按钮集成于一体，可以减少按钮数目。 -VC produced by the button with a pop-up menu button with a pop-up menu can make a button with a multiple-choice functions, extended functions of the button, which is equivalent to integration of multiple buttons in one can reduce the number of buttons.
