摘  要：對跳汰生產過程中能間接反映出床層松散度的浮標信號進行小波分析，數據分析表明，不同的松散度對應的頻帶能量不同，提出了用頻帶能量作為表征床層平均松散度狀況的特征向量。  關鍵詞：跳汰機   浮標信號   小波分析   松散度 Abstract: In the paper Wavelet is used to analyze signal of buoy, which can indirectly reflect information of dilation of jig bed. Data analysis indicates that different dilation corresponds different energy in different frequency band, so we select ener[登陸后可查看全文]
