frequency ringing meaning in Chinese
频率区别振铃
Examples
- 3 . material samples are tested by this system and software in the frequency rang of 8 - 12 ghz . finally , uncertainty has been analyzed and advanced methods for test
3 .在8 12ghz的频率范围内,利用研制的测量系统及软件对样品进行了实验研究,对实验结果进行了不确定度的分析,并针对实验遇到的情况提出了改进措施。 - The arcs representing grain interior conduction mechanisms appear on all complex impedance plots , and occur at high frequency rang and contract with temperature . however , those arcs representing grain boundary and occurring at low frequency range were observed only in a small number of experimental runs
而反映颗粒边界导电机制的阻抗弧并不明显，两种阻抗弧出现在不同的频率范围内，反映颗粒内部导电机制的阻抗弧出现在频率较高的范围内，而反映颗粒边界导电机制的阻抗弧出现在频率相对低的范围内。 - For recent years , adsl has world widely employed and widely used in many aspects such as vod , remote medical treatment and e - shopping etc . but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals , and the adsl ' s frequency rang is from 0 to 1 . 104mhz , so we must confront the signal attenuation , the loop line noise impairments , the crosstalk interferences , the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks
近几年来， adsl在世界范围内得到充分的使用，广泛应用于视频点播、远程医疗、网上购物等各个方面。但是由于电话线网络是专门为传输低频信号而设计，而adsl的频谱范围在0 1 . 104mhz内，因此在传输adsl信号时，面临着信号衰减、线路噪声、串音干扰、桥接抽头反射和射频干扰等等多方面的问题，这就要求在adsl开通之前对线路进行一系列的测试。
