摘　　要：对盒式录音机机芯最重要的质量标准——带速抖晃率进行分析，建立了能分析各零件制造误差对放音带速抖晃率影响的动力学模型，并将用本模型进行大量计算的结果与实验结果进行对照。In this paper, the velocity fluctuation rate, the most important criterion of quality for a tape recorder, is analyzed. A dynamic modeling formula is developed, by which the fluctuation rate is mathematically connected with the manufacturing errors of the elements. And also, the results of a regressive analysis are given to demonstrate the effectiveness of the modeling.
