用法例句

A new frequency correction method was obtained,suitable for the situation of high-order harmonic generation,and this method was proved by two simulation experiments.

采用相位差法对工频频率测量进行了研究,推出了频率校正的计算公式;研究了窗函数和窗长度的选择对校正精度和响应时间的影响,在窗长度足够长的情况下,采用布莱克曼窗、凯泽窗有很高的校正精度;为提高响应速度,推导出了窗长为一个工频周期的傅立叶系数的计算公式,得出只含单频成分时,仍能够采用相位差法对频率进行校正,而当含有高次谐波时不宜直接采用相位差法的结论;还得到一种新的频率校正方法,该方法适合含有高次谐波的情况;通过给出的两种模型进行仿真实验,验证了理论结果的正确性。
