Secondly, three single deck blast vibration signals were analyzed by wavelet packet based on software MATLAB and the change of energy distribution curve at different frequency bands was obtained.

其次，基于MATLAB时爆破振动信号进行小波包分析，得到了爆破振动信号在不同频带上的能量分布图。

We are more likely to make this transformational change when the initial curve is still on the rise, since resources, energy and confidence are high.
