无线传感器网络自组织成簇问题优化模型 为了有效延长网络的运行时间，需要设计能量最优的自组织成簇机制，以适应传感器网络的特点。本文提出了一种适合无线传感器网络的能量有效的成簇优化模型。-Self-organizing wireless sensor network problems optimization model cluster in order to effectively extend the network run-time, the energy necessary to design the optimal mechanism for self-organizing clusters, in order to adapt to the characteristics of sensor networks. This paper presents a wireless sensor networks for energy efficient cluster optimization model.

单片机不具有SPI或相同能力的接口，为了便于与TLC2543接口，采用软件合成SPI操作，本文给出了用单片机HSO口模拟SPI接口时序的方法，对程序稍加改动就可适用于其它带SPI接口的器件.附加有c语言程序-SCM is not the same capacity or SPI interface, in order to facilitate and TLC2543 interface, using software synthesizer SPI operation, this paper, the SCM HSO SPI interface timing simulation methods little change in the procedure can be applied to other SPI interface with the device. Additional language program is c

西庇阿立即下令停止追击，罗马军重新列阵。在两场血战之后罗马军总数只剩两万人前后。他们的面前则是以逸待劳的汉尼拔精锐两万四千人，此时汉尼拔阵的正面首次宽于罗马军，罗马军处于数量、体力和阵法的三重不利地位。然而在双方开始进军之时西庇阿下令罗马军的后两个战列脱离阵形，快速向两侧移动，使得罗马军从三列标准阵变成一字长蛇阵，正面宽度反压倒汉尼拔，力图凭借阵形优势两翼包抄、决一死战……”
