The angle of refraction at total optical reflection is analyzed.
分析了光学全反射现象发生时的折射角,指出这时的折射角是一个复数,其实部等于π/2,虚部决定了光疏介质中渐消光场的衰减常数,给出了用虚部表示的Snell折射定律。
Aiming at the fault detection of train angle cocks currently,this paper introduces a intellectualized fault defection instrument of train angle cocks based on AT89C51 MCU.
针对目前折关检测的缺点,介绍了采用AT 89C51单片机为核心,设计一个智能化列车折关检测装置;在详细分析列车制动原理的基础上,重点讨论了系统的工作原理和硬件设计,采用独特的检测手段;该系统能够及时检测出列车折角塞门是否被关闭,并蜂鸣报警及测量管压;系统投入运行后,应用结果表明,该检测系统运行稳定可靠,检测精度高,检测精度达到了±2节内,具有很大的推广价值。
