DT-2100型多普勒血流探测仪性能测试方法的研究

Research of test ways of the DT - 2100 type dopplerblood stream detector's function

本文对DT-2100型多普勒血流探测仪的三项主要性能,超声多普勒探头的工作频率、血流速度、心率的测试方法进行研究和介绍,并通过直接法和频移法的对比着重探讨血流速度的测试方法。

This article is mainly about the research of test ways of the three main funtions of the DT - 2100 type Doppler blood stream detector: the frequency of the ultrasonic Doppler probe, the speed of blood stream and the rate of heartbeat, especially discusses the lest way of the speed of blood stream through the comparison of the direct way and the frequency movement way.
