udptransport
- 基于UDP实现简单的可靠数据传输 由于数据是在不可靠的信道上传输的,因此数据在信道上传输时可能会发生比特错误,数据丢失。Rdt3.0及之前的版本都是停止—等待协议,它限制了网络底层硬件的能力。为克服这个问题引入了流水线技术,两个能恢复流水线中的错误的基本方法:第N个分组重发和选择性重复。综上,要实现差错编码,顺序号,计时器,分组确认,滑动窗口,拥塞控制。-simple UDP based on the reliable data transmission of data is not rel

- 电子指南针设计与实现 摘 要 早期的指南针采用了磁化指针和方位盘的组合方式,整个指南针从精度、指示灵敏度、使用寿命上都有一定不足。本系统采用专用的磁场传感器结合高速微控制器(MCU)的电子指南针能有效解决这些问题。 系统采用了磁阻(GMR)传感器采集某一方向磁场强度后通过MCU控制器对其进行处理并显示上传,通过对电子指南针硬件电路和软件程序的分析,阐述了电子指南针基本的工作原理及实现。能够在LCD上根据当前位置显示方位。 关键词:电子指南针;GMR;MCU;LCD -A

- 色谱法 chromatography 薄层色谱 法又称“色谱分析”、“色谱分析法”、“层析法”,是一种分离和分析方法,在分析化学、有机化学、生物化学等领域有着非常广泛的应用。色谱法利用不同物质在不同相态的选择性分配,以流动相对固定相中的混合物进行洗脱,混合物中不同的物质会以不同的速度沿固定相移动,最终达到分离的效果。色谱法起源于20世纪初,1950年代之后飞速发展,并发展出一个独立的三级学科-色谱学。历史上曾经先后有两位化学家因为在色谱领域的突出贡献而获得诺贝尔化学奖,此外色谱分析方法还
