Using Beckers method, we calculate the interfacial energy between two liquid phases in an immiscible system. Based on the Gibbs-Thomson equation, the force acti
青龙满族自治县电视转播台建在青龙满族自治县县城南大山山顶上,海拔684 m,铁塔高度76 m,早些年,每到雨季,台内时有雷击现象发生,击坏配电系统等,造成停播,不仅经济上造成不
An algorithm for constructing a class of compactly supported symmetric/antisymmetric B-spline wavelets is presented.For any m th order and k th order cardinal B
In this paper, the existence of solutions is studied for nonlinear impulsive Volterra integral equations with infinite moments of impulse effect on the half lin
The origin, existence and evolution of life on the earth depend on the negative entropy flow in the terrestrial system (TS). In this paper, we investigate the m
Reproductive behaviors are poorly known for the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis. In this study, the parentage of an isolated Y
根据动态仿真的实时性要求，对化工过程动态分布参数模型，提出了空间时间分步离散化的处理方法，即先只对空间自变量作离散化处理，将动态分布参数模型中的偏微分方程化成以时间为自
