The flood developing procedure after clay dam bursting is ascertained by using semi-theoretical and theories semi-empirical relationship, which can provide some scientific basis for the feasibility research of the scheme of Taohe River's comprehensive treatment. 利用半经验半理论公式推求土坝溃决后的洪水演进过程,从而可为桃河综合治理方案的可行性研究提供一定的科学依据,也可供有关部门参考。
In this paper penetration depth of a horizontal jet in a fluidized bed and the influence factors are analyzed theoretically. After a series of experiments have been made with two and three dimentional fluidized beds, a semi-empirical relationship for calculation of the penetration depth is worked out. 本文对流化床中水平射流穿透深度及其影响因素从理论上进行了分析,在二维和三维试验台上进行了实验,得到了计算射流穿透深度的半经验公式。
The Prandtl semi-empirical turbulent theory is applied to deduce the expression of the relationship between the hydraulic factors of ice-covered rivers. 本文应用Prandtl半经验紊流理论,推导得到封冻河道水力要素间的理论关系表达式,并对冰盖影响区与床面影响区的交界位置进行了分析讨论;
