笔者发现2008年全国初中物理竞赛复赛试题的第5题的三联吊瓶问题。乍一看实际操作可行,但细想这一试题可以用,但在医院实际操作中不可行。下面对此题进行分析:医院里的护士使用如图1所示的装置给患者输液,小雨发现应用这一做法,护士为患者更换药瓶比较麻烦,于是就设计了图2所示的三瓶串接的方案,请分析回答;1.图1中药液能否会匀速滴下。2.图2中哪个药瓶中的药液先流完?为什么?3.根据病房的现有条件,如果需要估测输液过程中的一滴药液的质量,需要收集那些数据,请写出表
I found that the 2008 National Junior Physics Competition semi-final exam question 5 of the triple-drop bottle problem. At first glance practical work, but think carefully this question can be used, but not practical in the hospital. The following analysis of this question: The hospital nurses use the device shown in Figure 1 to patients infusion, rain found that the application of this approach, nurses replace the bottle for patients more trouble, so he designed the three bottles shown in Figure 2 Concatenation of the program, please analyze and answer; 1 in Figure 1 whether the liquid drops will be uniform. 2. Which medicine bottle in Figure 2 is finished first? 3. According to the current condition of the ward, if you need to estimate the quality of a drop of liquid during the infusion, you need to collect those data.
