摘要
振弦式仪器监测的物理量与仪器的频率模数或频率的平方具有统计关系,一般呈直线关系,所以通常采用一元线性回归拟合,如果通过数值分析的最小二乘法进行曲线拟合处理,对于振弦式安全监测仪器的检验可以得到较好的拟合效果,使得检验结果更加合理,并减小误差。
The monitoring physical quantities of the vibrating-wire safety monitoring instruments have a statistic relationship with its frequency modulus or the square of frequency; which generally shows a line relationship, and then usually is fitted with the unary linear regression method. If the curve fitting is processed with the method of the least squares for the numerical analysis, a better fitting effect can be obtained for the testing of the vibrating-wire safety monitoring instruments and a more reasonable testing result can be got with less errors as well.
