摘 要:Ordinary the Doppler effect in blood now was explained with thevariation of period or wavelenth. From vector compositing, the Doppler errect inblood flow is now explained with the variation of propergation velocity of ultrasound in different coordinates systems. The basic rormula of Doppler frequencyshift is derived' The experimental results are discussed.SOURCEOFDOPPLEREFFECTINBLOODFLOWWangWeiqi,YuJianguo,ShaoQianming,YiYanhua(DepartmentofElectronicEngineeringFudanUniversity,Sh...
