摘要翻译：
能够测量时间，无论是直接的还是间接的，对有机体来说都是一个显著的优势。它允许对规则或预测的事件做出及时的反应，减少快速处理感官输入的压力。因此，时钟在生物学中是普遍存在的。在本文中，我们考虑了不同构型下的最小抽象纯时钟，并研究了它们的特征动力学。我们对最佳时间分辨时钟特别感兴趣。其中，我们发现了基本的径向时钟特性，例如，对于纯局部时间测量或基于衰减的时钟测量对问题全局尺度的时间周期的振荡行为。我们还包括独立时钟集（“时钟包”）、时钟的顺序级联和具有受控依赖性的复合时钟。钟级联表现出“凝结效应”，复合钟表现出明显不同动力学的各种状态。

英文摘要：
  Being able to measure time, whether directly or indirectly, is a significant advantage for an organism. It allows for the timely reaction to regular or predicted events, reducing the pressure for fast processing of sensory input. Thus, clocks are ubiquitous in biology. In the present paper, we consider minimal abstract pure clocks in different configurations and investigate their characteristic dynamics. We are especially interested in optimally time-resolving clocks. Among these, we find fundamentally diametral clock characteristics, such as oscillatory behavior for purely local time measurement or decay-based clocks measuring time periods of a scale global to the problem. We include also sets of independent clocks ("clock bags"), sequential cascades of clocks and composite clocks with controlled dependency. Clock cascades show a "condensation effect" and the composite clock shows various regimes of markedly different dynamics.
