5) cutout days
断流历时
1.
According to the cutout characteristic data of the lower reaches of the Yellow River,and by using mathematical statistics methods ,the cutout days and length law and correlative relation among several characteristic factors in the lower reaches of the Yellow River are probed.
根据黄河下游断流特征观测数据,应用数理统计方法,分析其时空分布规律,探讨断流特征要素间的相关关系;应用随机数学等方法,建立预测模型,分析黄河下游来水、用水、降水及断流历时发展趋势,并进行断流长度等预测。
2.
According to the cutout charactoristic data of the lower reaches of the Yellow River,and using mathematical statistcs methods, the paper analyses the correlative relations among the cutout days,cutout length and the amounts of the silt accumulation in the lower reaches of the Yellow River.
根据黄河下游 1972～ 1997年断流特征观测数据 ,应用数理统计的方法 ,分析了黄河下游断流河长、断流历时和泥沙淤积量之间的相关关系 。
6) runoff starting time
产流历时
1.
Using the two indexes of runoff starting time and steady infiltration rate,the infiltration features of the soil were analyzed.
利用人工模拟降雨对黑龙江西部半干旱区坡耕地不同坡度和不同降雨强度下的土壤水分入渗规律进行了试验研究,采用产流历时和稳定入渗速率二项指标进行分析,发现随着地面坡度的增大,产流历时提前,稳定入渗速率逐渐减小,坡面产流历时与坡度呈对数函数关系,土壤稳渗速率与坡度呈幂函数关系;随着降雨强度的增大,产流历时提前,稳定入渗速率逐渐增大;坡面产流历时与降雨强度呈指数函数关系,土壤稳定入渗速率与降雨强度也呈指数关系。
