一、生物节律的性质及类别 生物系统组成的一项重要原则是维持体内平衡,保持体内各种可变化的功能恒定。在此恒定的基础上,体内各种功能仍有重复的节律性变化。这种生物节律变化对维持体内平衡来说是非常重要的补充。 生物节律可存在于单细胞、器官与组织、整个机体或个人群中,其频率的范围很大,可自每毫秒到每数年一个周期,如神经冲动的周期是1/毫秒,脉博是1/秒,LH的脉冲式分 First, the nature and classification of biological rhythms An important principle of the composition of biological systems is to maintain body balance, to maintain a variety of variable functions in the body constant. On the basis of this constant, there are still repeated rhythmic changes in various functions in the body. This change in biorhythm is a very important complement to maintaining homeostasis. Biological rhythms can exist in single cells, organs and tissues, the entire body or individual population, its frequency range from every millisecond to every one year cycle, such as nerve impulses cycle is 1 / ms, pulse is 1 / s, LH pulse-type points
