n个简谐振动合成的待定参数法

Synthesis Formulae of n Simple Harmonic Vibrations Based on Undetermined Parameters Method

运用待定参数法推导了n个同频率、同方向简谐振动的合成公式,讨论了合成公式的若干特例;并以此为例阐述了待定参数法解决数理问题的一般原则、应用技巧及其方法论意义.

The synthesis formulae for n simple harmonic oscillators with the same vibration direction and frequency are deduced based on method of undetermined parameters,some special examples are numerated and analyzed concretely in illustration of the synthesis formulae. On the other hand, the application principles, procedures and application fields of this method are also thrown light on and discussed in detail.
