摘要

通过实验，我们发现了一个包含湍流反应流的非强制系统中的奇异非混沌吸引子。虽然模式表明sna在动力系统中很常见，但实验观测主要限于具有外部强迫的系统。我们在混沌波动出现周期振荡之前观察到SNA。在复杂系统中，自组织可以导致有序，而固有的非线性可以导致混沌。在这样一个复杂的系统中，SNA的出现是非混沌但非周期的，这是很有趣的。

Strange nonchaotic attractor in an unforced turbulent reactive flow system.

We discover strange nonchaotic attractor (SNA) through experiments in an unforced system comprising turbulent reactive flow. While models suggest SNAs are common in dynamical systems, experimental observations are primarily limited to systems with external forcing. We observe SNA prior to the emergence of periodic oscillations from chaotic fluctuations. In complex systems, self-organization can lead to order, and inherent nonlinearity can induce chaos. The occurrence of SNA, which is nonchaotic yet nonperiodic in one such complex system, is intriguing.
