In the middle of the 90s, Ren Ji-zhou and others systematically described the theory of system coupling which showed that system coupling is two or more potentially coupled systems, under artificial control of input and output of energy flow, material flow and information flow in larger systems, coupled to form new superior structure -function bodies. The general function of coupling between systems is to consummate the structu...
