反射波振幅与入射波振幅的比率称作反射率或反射系数。
The ratio of the amplitudes of the reflected and incident waves is termed the reflectivity or reflection coefficient.
结果表明，随着驱动电流振幅和频率的增加，该组分非晶丝的GMI比率均为先增后减；
The results show that the GMI ratios first increase and then decrease with the increase of each of them.
利用符号或帧速率来进行同步捕获，导出了与信道振幅无关的密集多径下同步捕获的广义似然比率测试(GLRT)，来估计出现在符号位的有效信号增益。
Timing acquisition is realized in symbol and frame rate and GLRT is derived under dense multipath channel, which is unrelated to the amplitude of the channel.
