东居延海的入湖水量是狼心山来水量中的一部分,两者之间的相关关系不显著。通过估算,狼心山到东居延海段的河道输水损失率远远高于黑河下游的正义峡到哨马营河段和哨马营到狼心山河段,河道输水损失率均值为57.96%。相对较高的河道输水... 东居延海的入湖水量是狼心山来水量中的一部分,两者之间的相关关系不显著。通过估算,狼心山到东居延海段的河道输水损失率远远高于黑河下游的正义峡到哨马营河段和哨马营到狼心山河段,河道输水损失率均值为57.96%。相对较高的河道输水损失率是入湖水量与狼心山来水量相关关系不显著的主要因素。采用最小二乘原理拟合得到的储水量与面积变化的多项式准确体现了储水量与面积两者之间的变化规律。通过分析东居延海水量损耗的因素,提出了在年内蒸发量高峰过后的时段向东居延海进行补水的合理化建议。 展开更多

An equation of atomization quantity from energy dissipation by hydraulic jump was derived from the dimensional analysis. By applying Gauss diffusion equation, the spray diffusion rule in valley was studied under the condition of continuous linear source and random wind direction.By considering the spray rain switching process, coagulation, condensation and evaporation of droplets, the air temperature, air relative humidity, spray density and the rainfall intensity in the lower reaches of the linear source were calculated. The 3 D numerical simulation fitted well with prototype monitoring. Finally, the prediction of atomization influence on environments for Xiangjiaba Hydropower Station was conducted. 展开更多
