【摘要】 本文报道了利用相对测量法,并加入衰减与衍射修正,测量与研究高声衰减生物媒质非线性声参量的结果。表明:心、肝、脾、肾、肌肉组织的非线性声参量B/A为7左右;尿液、胆汁等水样液体的为6左右;脂肪组织的在9.6以上。分析了脂肪组织非线性声参量较大的原因,认为是由于其组织成份中类脂化合物较多所致。另外,还结合本研究,讨论了Ichida等人对脂肪组织非线性声参量的研究结果。更多还原

【Abstract】 Acoustic nonlinearity parameters of biological media such as heart, liver, spleen, kidney, muscle, fat, gall and urine are measured.The nonlinearity parameters of heart, liver, spleen, kidney and muscle are about 7, of gall and urine about 6, and that of fat is above 9.6.The arge nonlinearity parameter of fat is attributed to the high lipid content in it.Ichida’s result of fat is discussed.更多还原
