【摘要】 从利用焦利氏秤测定弹簧有效质量实验出发,研究了弹簧与重物组成的系统做简谐振动时,弹簧形状和质量等参数对弹簧有效质量的影响,分析了开始计时的取点问题以及使用不同数据处理方法所带来的影响,并对所用开放式教学方法进行了探讨.更多还原

【Abstract】 For the experiment of measuring the effective mass of the spring,we study the effect of the shape and mass of spring and the starting point of recording time on the effective mass of the spring. We also compare the calculations of two kinds of data processing methods and discuss the open teaching methods.更多还原
