正弦序列 meaning in English

sinusoidal sequence

Faced with the fact that there is a great deal of noise in detecting signal when using small amplitude lasting sine current on field , a developed lease minimum squares method is adopted , which makes the parameters of sine sequence with known frequency picked up on the real time . at the same time , original signal is processed by using wavelet theory , gaining true information which responses to the coating quality
在小幅度正弦恒电流激励检测中，针对现场检测信号含有大量噪声这样的情况，采用改进的最小二乘法,实现频率已知的正弦序列参数的实时提取；同时利用小波理论对原始信号进行处理，得到反映涂层性能的真实信息。
So by analyzing the stability of voltage vector and the changeability of current vector , we proposed to construct sinusoidal sequences with the same and delaying ninety - degree phase angles to voltage vector , then to multiply with the current vector respectively to bring about active and reactive power
本文分析了单相系统电压矢量的稳定性以及电流矢量的多变性特点，提出了对电压矢量采用构造与之同相位和滞后90相位正弦序列的办法，并分别与电流矢量相乘从而导出其有功和无功功率。
