In this paper we attack the problem of understanding the localization of the main structures involved in the motor circadian rhythm of crayfish by analysing its ontogeny. We present experimental results giving the properties of this rhythm in young and adult crayfish. Then we construct a mathematical model (based on a previous one for the electroretinogram circadian rhythm in the same species) simulating those properties. In the process of constructing the model we clarified and made precise various hypotheses about the biological structures involved in them and about the characteristics of the oscillators present in those structures. We also formulate some hypotheses about the general properties of circadian rhythms. Finally, we propose some experiments suggested by the mathematical model.
在本文中，我们通过分析小龙虾运动昼夜节律的个体发育来研究理解其主要相关结构定位的问题。我们展示了关于幼体和成体小龙虾这种节律特性的实验结果。然后我们构建了一个数学模型（基于之前针对同一物种视网膜电图昼夜节律的模型）来模拟这些特性。在构建模型的过程中，我们阐明并明确了关于其中涉及的生物结构以及这些结构中存在的振荡器特性的各种假设。我们还提出了一些关于昼夜节律一般特性的假设。最后，我们提出了一些由数学模型启发的实验。
