experiment packet的意思|示意

Enclosing damage diagnosis, this pape studies modal experiment in ambient excitation, optimal placement of sensors and structural damage alarming using wavelet packet energy spectrum.

本文围绕结构损伤诊断，研究基于环境激励的模态试验方法、传感器优化布置原理和小波包能量谱损伤预警方法三方面的内容。

At last, the experiment to testing is finished. The test indicates that the packet filter based on NDIS intermediate driver have the advantages of high efficiency and practicality.

最后完成了实验验证，结果表明，基于NDIS中间驱动的包过滤器具有高效和实用的优点。

Dynamic signals measured from experiment beams are first decomposed into wavelet packet components, then the wavelet energy rate index is computed and used to detect location of damage.

首先，将得到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来进行损伤定位。
