一.前言动脉是循环系的重要环节。但在讲解动脉血流、血压、脉搏及影响动脉压的因素等问题时,要花很大的篇幅,相关的实验也十分繁杂。为了配合讲课,笔者设计了一种简易的实验,通过约一刻钟的时间在课堂演示,大部分讲授内容都已明确,并留下深刻印象,因此理论讲述只需要半小时,并可收到较好效果。当然此实验还很简陋粗糙,有待于进一步的改进。
I. Introduction Arteries are an important part of the circulatory system. However, when it comes to the problems of arterial blood flow, blood pressure, pulse rate and the factors that affect arterial pressure, it takes a lot of time and the relevant experiments are very complicated. In order to tie in with lectures, I designed a simple experiment that demonstrated in the classroom about a quarter of an hour, most of the teaching content was clear and impressed, so the theory lay in only half an hour and received more Good effect. Of course, this experiment is still very rough and needs further improvement.
