The cavity can be divided into two typical zones: the Rayleigh_Benard-like convection zone governed by the centrifugal buoyancy force occupying the upper cavity, and the forced convection zone governed by the inertial-force down under. These two zones interact with each other via the exchange of mass, momentum and energy.

In history and reality, the contradiction between needs and limited resource always exists. From the view point of system-science, it can be concluded that:①The interaction among need-contradiction-ability is the perpetual force for enterprise evolution (and the evolution of other living systems). The improvement of "ability"is the process and result of evolution.②The competition and coordination among systems is the direct power for enterprise evolution. Competition produces various system actions. Coordination makes systems complement their functions with each other. The interactions of competition and coordination push enterprise into the flow of evolution and optimization.③The"stochastic fluctuation"of the system, which is accidental finding, is another force for enterprise evolution. It is a deterministic element in the process of the self-organization of enterprise.

An electromotive force which is called hall electromotive force comes into being.

一個成為霍爾電動勢的電動勢就是這樣由來的。

In the analysis, firstly, the flux boundary condition is used to simulate the frictional heat resource between wheel and rail. The non-steady heat transfer between the contacting surfaces of the wheel/rail, heat-convection and radiation between the wheel/rail and the ambient were all taken into consideration. Therefore, a heat coupling model of the wheel/rail in rolling/sliding is put forward to calculate the frictional temperature rise in the wheel and rail. Secondly, after the temperature distribution of wheel/rail, due to friction, is calculated, substitute the thermal load with equivalent fictitious body force and boundary distributed force loaded on the nodes of the corresponding elements. The wheel-load is applied to the center of the wheel.

Velocity is a measurement of speed and has nothing to do with mass; however, force is a vector that is applied to the particle to change the particle velocity, and when it is applied, mass is taken into consideration (acceleration = force / mass).
