功率衰减 meaning in Chinese
power attenuation
Examples
- The quality assurance is that power declines not exceed 10 % in ten years and 20 % in twenty - five years
本公司生产的太阳电池组件质保十年内功率衰减小于等于10 % ，二十五年内功率衰减小于等于20 % 。 - The designs and realizations of the representative radio frequency modules , such as power attenuator , directional coupler , filter , small signal amplifier and oscillator , were emphasized
重点分析了典型射频模块电路(如：功率衰减器、定向耦合器、滤波器、小信号放大器和振荡器)的设计和实现。 - The paper discussed a fundamental theory that microwave can be used to determine the carbon content , introduced a certain relationship between the attenuation of microwave and carbon content in fly ash and designed a microwave measuring system
克服了取样式测碳仪存在的问题。论文讨论了微波测碳的基本原理，介绍了微波功率衰减与飞灰中的碳之间存在着确定的关系。 - To solve the proplems effectively , this paper put forward a method . in this paper , the developmental status is analysed about domestic technique and market in fiber monitor and test , then the framework is designed in hardware , and devices is choosed reasonably . the system monitor and test the spare optical fiber in optical fiber network in place of the status of the optical cable
本论文针对上述问题,提出了基于光功率衰减检测的故障判断的解决方案。本文首先分析国内的光纤监控市场和监控技术的发展,进而在硬件结构及设备选用上提出方案。系统使用光纤网络中的备用光纤用于监控和测试,代表整条光缆的情况。 - Optical power meter real - time monitor optical power of each optical cable , and control computer gather the value of optical power attenuation circularly , if some values excess the limit , the computer control optical switch to connect another spare optical fiber with otdr card , control the otdr card to test the optical fiber , and then find the malfunction point accurately . the system require software system to run with hardware devices tother . this paper analyze requirement and technical feasibility in software system , ooa and uml are used to analyze software and abstract the class diagram
通过光功率计对每条光缆中的备用光纤进行实时的监控,测试光功率的衰减值,主控计算机不断循环的对每个光功率模块进行数据采集,并记录每路光信号的光功率衰减值,然后进行分析处理,如发现达到设定的光功率衰减门限值就报警,并控制光开关的切换,将故障光缆中的另一备用光纤与otdr卡连接,通过otdr卡对该光纤进行测试,从而确定故障点。
