连通器问题是我们在选修3-3中经常碰到又是比较难的问题,笔者认为主要可以抓住几个关键点:第一,属不属于连通器模型;第二,抓住液体体积不变;第三,大气对研究的系统做功代数和为零;第四,善于利用液体等效体积的方法来处理问题.下文将通过几个例题来讨论说明.一、机械能与内能间的相互转化问题
Communicator problem is often encountered in the elective 3-3 is more difficult problem, I think the main points can be grasped a few: first, belongs to the communicator model; second, to seize the liquid volume is not Third, the atmospheric system of research on the work of the power generation and zero; Fourth, good at using the liquid equivalent volume method to deal with the problem. The following will be discussed by a few examples to illustrate. First, the mechanical energy and internal energy mutual Conversion problem
