| 摘 要： | 对武汉大学电波综合观测站于１９９１年的降雨曲线进行测量，当采样时间为５ｍｉｎ时，用单变量雨强时间序列进一步研究了降雨这一大气过程中雨强分维数随时间的变化特性．结果表明，在灾害性降雨天气前后其雨强分维数仍然发生了显著性的改变．

| Abstract: | We have made a further study on the temporal characteristics of fractal dimension of rainfall rate in a single variable rainfall rate time series,with rainfall curve measured at Wuhan University Comprehensive Radio Observatory in 1991.The sampling time is 5 minuts.It is demonstrated that during a disastrous rain,there is a significant change in the fractal dimension of rainfall rate. |

| Keywords: | single variable time series rainfall rate fractal dimension |
