中文摘要：
基于短时间的非静止的随机的信号，在最大的 decking 费用之间的关系和爆炸的精力分发的字符颤动信号借助于小浪包方法被调查。第一，小浪变换的特征和小浪包分析被描述。第二，爆炸颤动信号被小浪包在不同频率乐队基于精力分发曲线的软件 MATLAB，和变化分析被获得。最后，随着最大的 decking 变化的颤动信号控告的爆炸的精力分发的法律被分析。结果证明随 decking 充电的增加，到全部的精力的高频率的精力的比率减少，颤动表明的爆炸的主导的频率乐队向低频率趋于，爆炸颤动不取决于最大的 decking 起诉。
英文摘要：
Based on the character of short-time non-stationary random signal, the relationship between the maximum decking charge and energy distribution of blasting vibration signals was investigated by means of the wavelet packet method. Firstly, the characteristics of wavelet transform and wavelet packet analysis were described. Secondly, the blasting vibration signals were analyzed by wavelet packet based on software MATLAB, and the change of energy distribution curve at different frequency bands were obtained. Finally, the law of energy distribution of blasting vibration signals changing with the maximum decking charge was analyzed. The results show that with the increase of decking charge, the ratio of the energy of high frequency to total energy decreases, the dominant frequency hands of blasting vibration signals tend towards low frequency and hlasting vibration does not depend on the maximum decking charge.
