| Abstract: | With spectral difference method,ultrasonic transfers attenuation properties . of pigs fat,muscle and liver,respectively are studied.The result shows that the relations of attenuation coefficients vs.ultrasonic frequency excellently correspond to exponential laws for pigs fat and muscle and the relation of pigs liver corresponds to linear law nearly. |

| Keywords: | ultrasound attenuation coefficient fat muscle liver laws fit |
