摘 要: 基于“能量公设”和“广义场协同”理论 ,从非平衡热力学和能量守恒两个角度出发 ,推导出外场作用下传质推动力的一般形式。证明外场下 ,传质推动力—热力学系统的化学势除了与温度、压强及各组份摩尔数有关之外 ,还与外场的特征参数有关 。 Based on “Energy postulate”and “Generalized field synergism”, derived from nonequilibrium thermodynamics and energy conservation ,this paper investigates the general format for impetus of mass transfer.It is proved that under the outfield ,the chemical potential is not only decided by the temperature 、pressure and the mole number of every component, but also by the characteristic parameter of the outfield, Two examples——gravitational field and ultrasound field are discused.
