经济调度问题的平等的增量成本标准的解决方案介绍在满足约束条件的同时，经济负荷调度问题正在为最低成本分配荷载对植物。它被制定为同时满足的需求和损失最小化所有已提交的植物燃料总费用优化问题。变体问题是众多的模型约束条件和目标以不同的方式。基本的经济调度问题可以作为一个最小化所有已提交的限制条件下的植物燃料总成本最小化问题的数学描述。参考资料：Birge，B.，2003年，PSOT，A粒子群算法MATLAB工具箱，一切顺利

使用STC15W4K系列MCU发出带死区的PWM波，占空比可调，可用于驱动半桥电路，BUCk，BOOST带同步整流的驱动。使用本代码前，请到STC官网下载STC15W4K系列的头文件，这里不给出。使用函数set_pwm()可设置占空比，使用前要先初始化init_pwm().在初始化函数里涉及到PWM引脚，PWM周期，初始电位，是否在二分之一duty处触发ADC，初始占空比设置，使用时可以参照数据手册按需求修改，这里只是一个实际的应用例程，希望有所帮助。

PCI(外设部件互连)是当今个人计算机的主流总线结构，是微型计算机中处理器/存储器与外围控制部件、扩展卡之间的互连接口。PCI局部总线规范是互连机构的协议，也是电气和机械配置的规范。 本书分为9章，涵盖了PCI局部总线规范2.2版及其最新进展，详细介绍了PCI局部总线的原理和操作，内容包括PCI局部总线的基本概念、信号的定义、总线的操作、电气规范、机械规范、配置空间、66 MHz规范、BIOS和PCI-PCI桥等。书中通过大量的时序波形和实例对PCI局部总线的实际应用进行了深入浅出的阐述。 -PCI (peripheral device part interconnection) is now personal computer s mainstream bus structure, is in the microcomputer the processor/memory and between the periphery control portion, the expansion card interconnection connection. The PCI local bus standard is the interconnection organization agreement, is also the standard which the electricity and the machinery dispose. This book divides into 9 chapters, has covered the PCI local bus standard 2.2 edition and the newest progress, introduced the PCI local bus s principle and the operation in detail, the content including the PCI local bus s basic concept, the signal definition, main line s operation, the electricity standard, the mechanical standard, the disposition space, 66 MHz stand

通常的汉字显示方式是先根据所需要的汉字提取汉字点阵（如16×16点阵），将点阵文件存入ROM，形成新的汉字编码；而在使用时刚需要先根据新的汉字编码组成语句，再由MCU根据新编码提取相应的点阵进行汉字显示。在这种显示方式中，如果使用的流字数量较大或语句较多时，利用汉字的新编码组成语句将是一件十分繁琐而枯燥的工作。针对这种情况，本文提出了一种十分简单的方式――直接利用PC机的汉字内码作为单片机系统的编码。-Chinese characters are usually displayed in accordance with the need to first extract of the Chinese character dot-matrix (such as 16 × 16 dot matrix), will be deposited into the matrix documents ROM, a new Chinese character encoding while just need to use the Chinese characters according to the new code composed of statements, and then by the MCU according to the new code to extract the corresponding Chinese character dot-matrix display. In this show the way, if you use the word flow statement number of the larger or more, the use of Chinese characters composed of a new coding language will be a very tedious and boring work. In view of this situation, this paper presents a very simple way- direct access to PC-code character encoding as a single-chip microcomputer system.
