摘要: 对有质量弹簧的振子基频作近似这个命题,诸多作者提出了各自算式.我们选择近期给出的4个算式,用数值方法对它们进行了比较.给出了两个新构造的算式,它们具有较小的误差界.

关键词: 弹簧振子, 本征频率, 近似计算

Abstract: Many formulas have been put forward on the approximation to the eigenfrequency of the mass-spring oscillator. Four recently proposed formulas are compared by numerical methods. Two new algorithms are presented, which have smaller error bounds.

Key words: spring oscillator, eigenfrequency, approximate calculation
