摘  要：對跳汰生產(chǎn)過程中能間接反映出床層松散度的浮標(biāo)信號進行小波分析，數(shù)據(jù)分析表明，不同的松散度對應(yīng)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(guān)鍵詞：跳汰機   浮標(biāo)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]
