稳态是系统学等现代科学中一个重要的基本概念和理论。生理学家把正常机体通过自身的调节作用,使各个器官、系统协调活动,共同维持内环境的相对稳定状态叫做稳态。稳态概念源于对内环境的研究,后来逐渐发展成为适用于整个生物科学的基本概念。这从一个侧面反映出生物科学从分析走向综合、由分支走向统一的发展趋势。在稳态概念提出的过程中,贝尔纳、坎农和维纳等人都做出巨大贡献。
Steady state is an important basic concept and theory in modern science such as systematics. Physiologists to the normal body through its own regulatory role, so that all organs and systems to coordinate activities, to maintain the relative stability of the internal environment is called steady-state. The steady-state concept stems from the study of the internal environment and later evolved into the basic concept that applies to the entire biological science. This reflects from one side of the biological sciences from analysis to synthesis, from the branch to the unity of the development trend. In the process of putting forward the concept of steady state, Bernard, Cannon and Wiener make great contributions.
