rainfalls

in the experiment, the change of sediment rate and erosion rate were divided into the gradually increasing stage, rapidly increasing stage and remaining stable stage with the rainfalls time. the change curves fitted logistic model with a high accuracy.

坡面径流含沙率和侵蚀率随降雨时间的变化趋势都可分为缓慢增加、急剧增加和趋于稳定三个阶段，其变化趋势符合Logistic曲线模型，相关性显著。

several rainfalls soon followed, and brother tian always ploughed the land just in time to catch the water.

接着又下了几场雨，田师兄都把握时机马上翻地保持水分。

By a case study which analyzed the sliding mass engineering geological condition and structure of Taiping hill landslide, the author drew to a conclusion that the landslide was formed in a complex structure setting, due to mine exploiting and heavy rainfalls.

以北京周口店太平山西部滑坡为例，对滑坡体工程地质条件、滑坡体组构分析后认为，该滑坡在地质构造复杂的背景下，由人为开矿采空、大暴雨共同诱发形成。
