were attained using (1/25,000) stream secondary halo reconnaissance method on the basis of analysis result of 1/100,000 dispersion train reconaissance.
在研究了1∶10万分散流普查结果的基础上,采用1∶2。
Methods and effects for finding the anomaly sources by using 1∶25 000 dispersion flow;
用1∶25万分散流追踪异常源的方法及效果
The scope of backward dispersion is limited by velocity.
分散作用是污染物主要运移特性之一,逆流分散运动受到水流流速的影响,逆流分散范围将受到流速的限制。
So, based on the typic double pinnate drainage of the Bailianhe basin, the nonlinear concentration model of scattering input which is established on the reservoir mode of series-parallel connection are presented in this paper with the shape restriction.
考虑到长江流域复杂的地形特征以及降雨时空分布变化对流域汇流的重要影响,通过引入形状约束条件,建立了以串并联相混合的水库模式为基础的流域分散入流非线性汇流模型,从而较合理反映了白莲河流域这种典型的双羽形水系的汇流特性。
