| 摘 要： | 目的通过分析人体心脏做功的过程及大小，为医学工作者提供更多的医学信息。近几年来．在高考物理试卷中偶尔见到这方面的近似计算题，也为这类问题提供理论依据。方法运用流体力学中实际液体的伯努利方程，分析在血液循环过程中，心脏做功的过程及其近似计算的方法。结果建立血液循环的物理模型，运用实际液体的伯努利方程进行分析，可以计算出人体心脏做功的大小。结论掌握和理解心脏做功的过程和计算方法．对预防心血管疾病的发生有重要的意义。

| Abstract: | ObjectiveThrough the process and size analysis of human cardiac work, providing more information for medicine workers. In recent years, there are these kinds of calculation subjects in physics paper occasionally, which also provides the theory basis for these problems. MethodsUsing the Bernoulli equation for real liquids in fluid mechanics, analyzing the process and approxi mate calculation methods in the blood circulation process. Results Establish the physical model of blood circulation, and analyze u sing the Bernoulli equation for real liquid, we can calculate the size of the human heart. Conclusion Grasping and understanding the process and calculation methods of cardiac work, which has important significance to prevent the occurrence of cardiovascular dis |
