It will be very helpful to understand how the aberrations affect the course of three - wave mixing , such as the change of conversion efficiency , the distribution of intensity and phase 重点研究了位相畸变光束的倍频过程中,谐波的位相分布是否能与基波的波前畸变有一定的保真度,二者关系如何。
For example , to the frequency splitting between fundamental wave and second harmonics , the filter daub6 and cqf12 do well in extract the fundamental wave , whereas the filter daub5 and daub6 do well in extract the second harmonics 如对于基波与二次谐波的分频, daub6和cqf12滤波器对基波的滤波效果较好,而daub6和daub5对于二次谐波的滤波效果较好。
The magnetic field requirement of the sth harmonic gyroklystrons over cyclotron resonance masers ( crms ) would be reduced by a factor of s relative to operate on the fundamental cyclotron frequency , so that the amplifier could be applied to highly mobile millimeter wave radar systems 基于电子回旋谐振脉塞原理工作的谐波回旋速调放大器的工作磁场强度是基波的1 / s ( s是谐波数) ,因而能适用于机动性较高的军用毫米波雷达系统。
This way has been improved in this paper . whole - cycle fourier differential algorithm is adopted in record start - up to satisfy the real - time requirement . the least squares method is applied to extract the fundamental frequency component in location which has low computing speed but high precision 故障录波启动采用全波傅立叶差分算法,以满足启动实时性要求,测距所需基波的提取采用最小二乘法,适应其精度要求高而实时性无要求的特点。
Based on the large disturbance equation and using the measured power angle as an observation argument in an identification algorithm , the electrical parameters and mechanical parameters are obtained . in this thesis , micro - computer testing systems for synchronous generator is analyzed . withmcs - 196 series single chip micro - controller of high price performance ratio , a high precision , intelligent instrument for automated testing has been developed 设计了同步发电机参数测试仪器,完成了利用发电机定子电压电流的波形,辨识发电机参数的计算机软件,该装置运用锁相环技术自动跟踪和获取电量频率,进行交流采样,利用傅立叶算法求得电量基波的幅值、有效值,从而可获得三相有功功率、三相无功功率以及功率因数。
