摘　　要：详细讨论了谐振动法测量空气比热容比实验中对小钢珠谐振动过程的动态模拟和数学建模,结果表明谐振动系统和外界的气体交换的微量性是动态模拟成功的关键。The dynamic simulation and mathematical modeling of small steel ball harmonic oscillation process are discussed in detail in measuring air specific heat ratio experiment. The results show that the trace gas exchange between harmonic oscillation system and external is a key to the success of dy namic simulation.

关 键 词：动态模拟 数学建模
