Abstract: A stand system change in the(number-volume) structure would be through going up and coming down of the growth increment and death volume,it will take a new convert function,which may instigate evolution(number-volume) of stands in future.This(structure-function) keeps to form an unbalance state,stableand in order advancing stands system better than that of the past.Time-and-space evolution of stands system is changeable,which shows different diversity,its {x(N),y(V)} evolution on the"Power Class Table" that react on its ratio of energy change and wavelength.This indicates that there is the characteristics of wave and particle change in the production of matter and energy of stands system.
