The order of surface roughness under no-tillage with different standing crop stubbles is millet forage＞maize forage＞oats＞rape, while the order of the soil wind erosion modules is rape＞oats＞maize forage＞millet forage. The larger the soil wind erosion modules are, the smaller the surface roughness is.

留有不同直立作物残茬免耕土壤地表粗糙度草谷子＞草玉米＞莜麦＞油菜，土壤风蚀侵蚀率呈现相反的趋势，地表粗糙度越大，风蚀侵蚀率越小。

When new concrete with higher strength grade is cast, the higher the roughness of old concrete fracture surface is, the higher the interfacial bond strength of old-new concrete is.

结果发现：用分数维来表征老混凝土表面的粗糙度，其预测结果精度较高；在粗糙度较高的老混凝土表面上浇注较高强度的新混凝土，获得的新－老混凝土界面粘结强度较高。
