angle difference meaning in English
角度差
Examples
- Angle difference among power systems
系统间相差角 - In order to filter out the noise contained in effective optical signal , a new method using the blazed grating to enlarge the angle difference between noise and effective signal , and getting through the iris to get the effective signal was put forward
摘要为了滤除有效光信号中的光噪声，本文提出了一种利用光栅的闪耀特性将噪声和有效信号之间的夹角角度差放大，再通过光阑得到有效光信号的方法。 - The radiation patterns with and whitout radome are calculated , and the angle difference in the maximum field point of their main clot show the bse of the radome , the bse from - 15 degree to 15 degree in direction , that been calculated and compared with the excited experimented data shows they coincide quite well
有天线罩时的远区场和没有天线罩时的远区场相比较,两个主波束对应的角度差即是天线罩的瞄准误差,本文对方位扫描角从负15度到正15度进行分析。 - After the host computer sends the broadcast command to order measurement operation , all slave devices will start to sample the input signals synchronously . when the sampling operation has finished , devices installed on the capacitive equipments will calculate the phase angle difference ( oi ) between leakage current and the reference voltage signal , and devices installed on pt will calculate the phase angle difference between secondary voltage and the reference voltage signal ( ou )
我们把一个50hz的交流基准电源引到每台下位机内，主机发布一个广播命令要求pt和电容型设备上的监测装置同时采样，电容型监测装置计算出泄漏电流和基准源之间的相位差_ ( oi ) ， pt上的装置计算出二次电压与基准源之间的相位差_ ( ou ) 。 - Single chip needs too much time to calculate and we ca n ' t detect power quality real time for example , and the sampling rate must synchronize the signal frequency . when sample multi - channel signal in turn , it must have time delay between two samplings , so the phase angle difference between each channel signal is ca n ' t be avoid and so on . those problems must be solved
本课题分析了目前电能质量的各种检测方法，认为快速傅氏算法（ fft ）是首选方法，但是基于定时采样的fft计算会产生频谱泄漏，为了减少这个泄漏需要进行加窗处理，这需要增加采样数据，导致显著增大计算量。
