摘要
以往对血流中的Doppler效应都是以周期变化或波长变化来进行解释的.本文从矢量合成出发,用不同坐标系统中声波传播速度的变化来解释血流中的Doppler效应.推导了Doppler频移的基本公式,并对一些模拟血流的实验结果进行了讨论.
Ordinary the Doppler effect in blood flow was explained with the variation of period or wavelenth. From vector compositing, the Doppler effect in blood flow is now explained with the variation of propergation velocity of ultrasound in different coordinates. The basic formula of Doppler frequency shift is derived. The experimental results are discussed.
