摘　　要：利用MATLAB提供的小波工具箱对所采集的敲击死花蛤、泥花蛤与活花蛤的声音信号进行小波变换处理,得到这些信号的时-频信号图谱。通过对比分析,提取各类花蛤的特征差异。以上结果可作为筛选死花蛤、泥花蛤与活花蛤的理论依据。The sound signals were processed with wavelet transform through wavelet box offered by MATLAB which were acquired by knocking at dead, slimy and live venerupis. These time--frequency atlas of the signals can be obtained and the corresponding features picked out by comparing and analyzing these signals, which can be used as the theoricai references while screening with dead slimy and live venerupis.
