Experiments on the earthquake model known as Burridge-Knopoff mode with self-made devices were conducted. The system of the model consists of some blocks and springs and the magnitude distribution(the relationship between the slip event size and its frequency) and time-interval distribution of the events were obtained. It was clarified that the system shows a critical feature in the small and medium magnitude regions while a characteristic feature in the large magnitude region. It was also clarified how these distributions depend on the parameters in the system(number of blocks, sandpaper grade, spring constant and so on).

利用自制的实验装置对Burridge-Knopoff模型进行了实验研究。模型系统由若干块体和弹簧组成，得到了滑动事件的震级分布（滑动事件大小与频率的关系）和时间间隔分布。结果表明，该系统在中小星等区域表现出临界特征，而在大星等区域表现出特征特征。还阐明了这些分布如何取决于系统中的参数（块的数量，砂纸等级，弹簧常数等）。
