实验的结果为：ISOVG68机械油作润滑油时，在输入3000rpm，5.96Nm时，齿面发现沿节线出现大面积的点蚀，且齿面有塑性变形；以3#油为润滑油时，在输入3000rpm，8.59Nm时，齿面发生了明显的齿面塑性流动，主动轮在节线处出现明显的沟槽，从动轮在节线处出现明显的棱脊，大小齿轮工作齿面均十分光洁，未发现点蚀现象发生。

It shows that runoff is closely correlated with the features of individual precipitation, and it is also affected by vegetation within a short period of time. Raindrop erosion, sheet flow erosion and rill erosion on the slope are the main soil erosion patterns; sediment yield occurs mainly in flood season. Human activity and individual precipitation are two important factors that control the soil erosion at a small watershed. Comprehensive management on the slope in a small watershed is an efficient measure of water and soil conservation.

分析表明，小流域的产流方式容易随次降雨条件的变化而变化，植被因素在较小时间尺度内就会影响产流；产沙主要来源于坡面上的溅蚀、片蚀和细沟侵蚀，时间主要集中在汛期；人类活动以及次降雨条件是控制小流域侵蚀产沙的重要因素；在小流域内进行坡面的综合治理是水土保持的有效措施。

Besides, when the experimental soil was clay soil of Yangling, the appearance and developing process of rill erosion happened respectively 12-15min and 4-8min earlier than of silt soil of Shaanbei.Accumulated sheet and rill erosion amounts increased with the rainfalls time, and the latter increased quickly than the earlier. The total accumulated rill erosion amounts were 2.5 and 5.5 times more than accumulated sheet erosion amounts.

黄绵土坡面发生细沟侵蚀的时间早于粘黄土坡面12-15min；坡面细沟侵蚀达到稳定的时间粘黄土坡面也比黄绵土坡面滞后约4-8min；累积面蚀量和细沟累积侵蚀量均随降雨时间的延续而增加，且后者增加幅度明显大于前者；降雨结束时，坡面细沟累积侵蚀量约为累积面蚀量的2.5～5.5倍，约占坡面总侵蚀量的80％以上。
