In the first part of the paper oscillating phenomena are discussed which one can observe on different levels in anorganic and organic systems. This discussion will be performed from physical, biorhythmic, control, and general system theoretical point of view. Especially biorhythmic phenomena are taken into account by the stated classification scheme. In the second part four numerical procedures for biomathematical analysis of biorhythmic oscillations are explained. The analysis is understood as determination of the number of harmonic suboscillations which set up the whole process, and calculating the values of frequency, amplitude, and phase of these suboscillations. To perform the mentioned four numerical procedures computer programs are available which are written in ALGOL.
在论文的第一部分，讨论了在无机和有机系统的不同层面上可以观察到的振荡现象。将从物理、生物节律、控制和一般系统理论的角度进行这一讨论。所阐述的分类方案特别考虑了生物节律现象。在第二部分中，解释了生物节律振荡生物数学分析的四种数值方法。该分析被理解为确定构成整个过程的谐波子振荡的数量，并计算这些子振荡的频率、振幅和相位值。为执行上述四种数值方法，有可用的用ALGOL编写的计算机程序。
