摘要
在普通物理的力学部分,关于简谐振动的分析,教材一般都从振子的微分方程出发,直接解微分方程得到简谐振动的特征。如果从振子状态入手,选择适当的物理量作为状态变量,就可以把简谐振动改为矩阵描述,用拉普拉斯变换求解。
In the General physical mechanics, about oscillation, teaching materials start with differential calculus equation, solve the equation directly and obtain the features of oscillation. If starting with oscillation state, proper variables chosen, we depict oscillation with matrix, and solve the problem of oscillation by Laplace transform.
