Delay line oscillator is composed of broadband amprifer adjustable attenuator and saw sensor device . after output signal of delay line oscillator is smoothed , it mixes with 109mhz local oscillation signal . its differential frequency signal is smoothed by low - pass filter trimmed by shaping circuit and processed by digital processing circuit 延迟线振荡器由宽带放大器、可调衰减器和声表面波质量传感器件构成。延迟线振荡器输出信号经滤波后与109mhz的本机晶体振荡器输出信号相混频，通过低通滤波取其差频，并经整形后由数字信号处理电路处理。
In studying the different methods of indicating the pronunciation of a chinese character by using two other characters between s . 2055 and other dictionaries of rhyming words , the author found what showed in s . 2055 might be some characteristics in oral language at that time , e . g . the voiced sound and voiceless sound use same initial consonant for the voiced sound had been voiceless ; there was misuse for the initial consonant between the group of zhi and the group of zhao 摘要本文通过研究s . 2055与其他韵书不同反切，认为所反映的可能是当时口语的一些特点：浊音声母与清音有混用，浊音已经清化了；知组声母与照组包括二等与三等有相混的现象；东冬钟归字混乱，三部不分；支脂之三韵也有交涉；微韵“蕲”存在之韵的又音； “解”字有平声一读。
Anthology : a hundred years is nothing but a chain of upheavals , a mix of gold and copper : difficult to know which is deception . this life is like a water bubble on a rainy afternoon ; one should strive lest it be too late to cultivate self - realization ! another visitor , ms . huang , had learned about the art exhibition from the tv program 她情不自禁地对著山竹果和开心两幅画唱起歌来，沉浸在师父无子诗劝修百年似一场风浪，金铜相混难以辨，人生如午后雨沫，不修何劫免？
