- An expansion wave in accelerating flow broadens.
- The tendencies of the IGS in our country are:1 The tendency of accelerated flow.
- Based on the axisymmetrical potential flow theory of an invicid incompressible fluid, the exact solution of an longitudinally accelerated flow passing an ellipsoid was obtained.
- Results The patients with stenotic left anterior descending coronary artery were found localized acceleration flow or retrograde flow by echocardiography.
- The blood flow was significantly weakened in the stenosis with irregular morphous, accelerated flow, widened spectra and fillings, whereas normal triphasic wave was not found.
