Abstract: In the year 1996, we found that, if the closed recycling reaction between acid?alkali?salt should be completed, we can be able to zero discharge in the clean production of chemical technology process. At the beginning of the year we study the acid?alkali united production from metallic salts by hydrolytic action as a new unit operation of chemical engineering. In the year 2012, we get up the theory of dynamic closed system with multy-phase and chemical kinetics, and find the third group from entropy to order structure in the nonequilibrium thermodynamics. If the new theory expanded to the solar system, we discover the closed circular flow of entropy and universal eternal self-motive machine, so we give the new definition of the times.

Key words: chemical technology process, circular economics, complex closed system, universal eternal self-motive machine

摘要： 1996年我们发现，如果能实现酸?碱?盐闭路化学循环，则化工清洁生产就能达到零排放。从此开始了盐水解法酸碱联产新化工单元的研究。2012年提出了“动态多相动力学封闭系统”理论，发现这是非平衡热力学中的第三类“熵致有序”结构。将这一理论推广至太阳系，发现了“熵循环流”与“宇宙永动机”，还给出了时间新定义。
