The topographical parameters have been analyzed by taking into account the thermal effect during the friction process. As the results, three kinds of typical topographical features have been observed for the worn surfaces of C G iron with various P content. Namely, C G iron with 0.05% P, 1.30% P, and 0.70% P show worn surfaces characterized by groove ridge, peak pits and their combined topography. The C G iron specimen with peak pits type worn surface topography showes the lowest wear rate and highest friction coefficient, while that with groove ridge type worn surface topography shows the highest wear rate and lowest friction coefficient. The groove ridge type worn surface has a relatively large value of surface height deviation and void volume ratio and negative large value of skewness, which is contrary to the peak pits topography.

Because change of volume reflected eroding process of watershed and surface change reflected change of topography surface, this model described relationship between watershed topograph and erosion.iv As a quantitative index of wateshed topography, topograph fractal demension can represent surface shape information of watershed topography in the round. Reseach find that watershed model and actual watershed show good fractal character. Topography fractal dimension related with process of development of watershed physiognomy and represented degree of watershed development, v Sediment yield intensity of watershed model reflected erosion characteristic of watershed model in different development phase.
