摘　　要：耗散结构结论内容为一个开放体系在达到远离平衡态的非线性区域时,一旦体系的某个参量达到一定阈值后,通过涨落就可以使体系发生突变,从无序走向有序,产生化学振荡一类的自组织现象。由于人体是由许多子系统组成的复杂系统,是复杂的耗散结构,所以耗散理论在医学上也会有广泛的应用,如酵解的振荡、跳动的心脏、人类的大脑都可被认为是耗散结构。耗散结构理论的提出突破了几个传统观念,如解决了热力学第二定律和达尔文生物进化论的矛盾、使非平衡态研究从被科学界忽视到重视等。目前耗散结构理论已成为横跨整个自然科学和社会科学的理论工具,向高等医学院校学生介绍耗散结构理论及其在医学、生物学等领域的实际应用和意义,有利于学生从一个新的角度考察人体健康。Dissipative structure theory means self-organized phenomenon such as chemical vibration while an open system reaches the nonlinear region far from equilibrium state, once some parameters of the system get to certain threshold, mutations will take place in the system through increasing and decreasing, from non-order to order. Human body is a complex system composed of multiple subsystems, which is a complicated dissipative structure, so it is extensively applied in medical sciences, such as zymolytic vibration, beating heart and human brain can be taken as dissipative structure. Dissipative structure broke out several traditional concepts; for example, it solved the contradictory between Second Law of Thermodynamics and Darwin＇s Organic Evolution Theory, and drew the scientific industry pay more attention to researches on nonequilibdum state. At present, dissipative structure theory has been a theoretical tool that across the whole natural science and social science. Introduction of dissipative structure theory and its practical application and significance in medical and biological regions to college students studied in medical colleges could facilitate the study of students on human health from a new angle.
