Description: 一 题目
全国铁路交通咨询系统
二 需求分析
1.系统配制：
硬件：CPU：P4 1.6G 内存容量 256M 标准输入输出设备
软件：操作系统Windows xp 源程序调试工具VC6.0
可执行文件运行工具 DOS 5.0.
2.该系统有供用户选择的菜单和交互性。
3.建立一个全国铁路交通咨询系统，该系统具备自动查找任意两城市间铁路交通的最短路径和最少花费的功能。
三 设计概要
1.抽象数据类型
本程序运用了关于图这种数据结构。
他的抽象数据类型定义如下：
typedef struct unDiGraph
{
int numVerts //结点
costAdj cost //邻接矩阵
}unDiGraph,*UNG
基本操作：
unDiGraph* CreateCostG()
操作结果：构造带权(费用)图。
unDiGraph* CreateTimeG()
操作结果：构造带权（时间）图。
PathMat *Floyed(unDiGraph *D)
操作结果：Floyed函数 求任意两点的最短路径。

Description: 凭借它在手机技术领域的地位、在射频半导体工艺方面的广泛知识，飞思卡尔提供了符合IEEE 802.15.4标准的MC13192射频数据调制解调器。这种功能丰富的双向2.4GHz收发器带有一个数据调制解调器，可在ZigBee™ 技术应用中使用。它还具有一个优化的数字核心，有助于降低MCU处理功率，缩短执行周期。4个定时比较器使用一个性能较低、价格低廉的MCU，从而能够降低成本。广泛的中断维修服务使软件开发更具灵活性。PF IC和MCU之间使用串行外围接口（SPI）连接，从而使用户能够使用飞思卡尔庞大产品系列中的任何一种MCU。连接质量和电源检测可为组网和维护提供必要的数据。MC13192提供的特性包括：
◆ 根据IEEE 802.15.4标准设计，采用ZigBee™ 技术
◆ 全频谱编码和译码
◆ 经济高效的CMOS设计几乎不需要外部组件
◆ 可编程的时钟，供基带MCU使用
◆ 标准的4线SPI
◆ 扩展的范围性能（使用外部低噪音放大器（LNA）功率放大器）
◆ 可编程的输出功率，通常为0 dB
◆ 超低功耗模式
◆ 7条GPIO线路

Description: This manual describes Freescale’s IEEE™ 802.15.4 Standard compliant MAC/PHY software. The Freescale 802.15.4 MAC/PHY software is designed for use with the Freescale MC1319x and MC1320x, family of short range, low power, 2.4 GHz Industrial, Scientific, and Medical (ISM) band transceivers, designed for use with the HCS08 Family of MCUs. The MAC/PHY software also works with the MC1321x family of short range, low power, 2.4 GHz ISM band transceivers that incorporate a low power 2.4 GHz radio frequency transceiver and an 8-bit microcontroller into a single LGA package.
Throughout this manual, the term transceiver refers to either the MC1319x, MC1320x, or the internal counterpart inside the MC1321x System in a Package (SiP).
