首先将所得的结构响应信号进行小波包分解，然后通过小波包能量变化率指标进行损伤定位。
Dynamic signals measured from experiment beams are first decomposed into wavelet packet components, then wavelet energy rate index is computed and used to detect location of damage.
第一，原子平均激发能量变化率是原子到板的距离的函数，并且当靠近板时以振荡行为消失。
First, the rate of change of the mean atomic excitation energy is now a function of the distance to the boundary and it dies off in an oscillatory way the boundary is approached.
