A Modified Hortonian Overland Flow Model Based on Laboratory Experiments

Overland flow, which is examined here, is an important hydrological response to storms of a catchment. And it is also a main component of hillslope hydrology. Through controlling of rainfall intensities and changing of artificial slope angles, 49 overland flow hydrographs are obtained from rainfall-runoff simulation experiments conducted on a manmade hillside. Based on the measured overland flow processes, the relationship between the average water depth on the hillslope and that at the outlet, which is nearly a quadratic curve, is obtained. The relationship is different from the assumption, in which the average water depth on the hillslope is equal to that at the outlet, proposed by Horton. Finally, a regression equation is also presented, which provides both the theoretical and experimental basis to modify the time delay of peak flow for a distributed rainfall-runoff modeling.

碳氮化钛粒度与熔渣粘度关系的研究

讨论了高钛型炉渣中ＴｉＣ，ＴｉＮ颗粒的粒度对其粘度的影响。在实验室测定了不同粒度的ＴｉＣ，ＴｉＮ在不同配加量下的高钛型高炉渣粘度和熔化性温度。用图像分析仪对ＴｉＣ和ＴｉＮ在渣样中的分散形态进行了分析。实验结果表明：在实验范围内，随ＴｉＣ，ＴｉＮ配加量增加，炉渣粘度增加；配加量相同时，无论是ＴｉＣ还是ＴｉＮ，细粒度较闰度和炉渣变稠作用更为明显。
