五行学说 《尚书·洪范》，“水曰润下，火曰炎上，木曰曲直，金曰从革，土爰稼穑”。 《国语· 郑语》，“故先王以土与金木水火相杂，以成百物”。 Non-linear Method The states of Wuxing system correspond to the states of the human body Model Dynamic model according to the relations between the five elements of Wuxing system Assume 8 candidate points for studying the stability of the system Results of Numerical Simulation We did two kinds of numerical simulation for studying Behavior of solution for the different initial values Reponse of the system to external stimlation Conclusion The dynamic model has the characteristic of self-organization. There is only on stable point with local stability in the five-dimensional space. There exists the instability domain in the five-dimensional space. The stability domain is unbounded and it contains several special subdomains composed of line-subdomains, ray-subdomains and segment-subdomains. In some ray-subdomains, there exists “comeback summits”. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 事物的五行归类 五行的归类主要采用类比取象的方法，按照脏腑生理病理的不同性质或表现，对照木火土金水的不同特性，进行归类 这种归类的主要目的，是想运用五行的关系阐明脏腑间的复杂联系 五行在中医中的作用更在于它对脏腑相互作用与联系的阐释 五行的相生相克 五行学说 五行相生，含有相互资生和助长的意思 生我者为母，我生者为子 五行相克，含有相互克制和制约的意思 五行关系是复杂系统关系表达最简单的一种 在事物复杂的相互关系中，不可无生，也不可无制；无生则不能发展，无制则坑而为害 保持生克平衡才能保证事物正常发生与发展 五行相乘相侮 如果五行发生太过或不及，就会出现五行相互克伐的异常现象，称为相乘和相侮 金 土 木 火 乘侮关系 水 相乘 相侮 五行相乘相侮 相乘含有乘虚侵袭的意思，与相克次序相同 相侮含有恃强欺侮的意思，与相克的次序相反 由于五行太过或不及而引起的乘侮关系往往会同时出现 如木太过，不仅乘土而且侮金 * * 阴阳五行的现代科学研究 阴阳五行能不能用现代科学的方法去描述它？ * * 阴阳五行的现代科学研究 Liver heart Kidney Lung Spleen L H Means: L growth conduce H growth L S Means: L growth conduce S restrain * * How to set up mathematics model?
