摘要
运用最小二乘法对多周期函数的周期进行筛选优化研究,对不同周期组引起的中误差精度做了分析与比对。
Based on the principle of adjustment, the optimal filtration of periodic group is discussed by use of least square method, and the error resulted from different period is also compared. After having analyzed and experimented, the theory shows its rigorous, practicable, and remarkable superiority.
