几百年来尤其是近二十余年的研究表明,节律性也是生命的基本特征之一.从单细胞生物到人类的各种机能活动、生长繁殖、乃至某些微细的形态结构,随着时间的推移,都可能呈现某种规律性的改变,这就是生物周期性(bioperiodicity)或生物节律性(biorhythmicity),亦称生物节律(biological rhythm).时间生物学, Hundreds of years, especially nearly twenty years of research shows that rhythm is also one of the basic characteristics of life.From monocellular organisms to a variety of human activities, growth and reproduction, and even some fine morphological structure, with the The passage of time, there may be some kind of regular change, which is the biological cycle (bioperiodicity) or biorhythmicity (biorhythmicity), also known as the biological rhythm (biological rhythm)
