【摘要】 不可逆在系统演化过程中,普遍地存在于系统自组织活动的不同层次上.它通过自同构与仅同构之间的矛盾运动,造成同类系统在空间上不断形成新的对称性破缺与新的自同构过程;它使系统经过若干自复制过程走向新的系统自组织演化形态;它使系统在自催化过程中从简单趋于复杂;它使系统的自反馈中始终存在着信息的新存储、选择与转化过程;它使系统不断形成新的自调控作用.它对系统自组织起着重要作用.更多还原

【Abstract】 Irreversibility exists universally at different levels of a system self-organization during the system evolution. By the contradiction between self - morphism and counter - morphism, it continuously makes new spatially symmetrical disjunction in a system of the same kind and results in new self - morphism processes. It causes the system to experience several self - reproduction processes and reaches a new evolution state of self -organization. With it,the system changes from simplicity to complexity in the process of self - catalysis; new data storage, selection and conversion comstantly exist in the system’s self -feedback process; and new self - control is continuously formed in the system. In one word,irreversibility plays an important role in a system’s self-organization.更多还原
