摘要：
在微重力条件下的二元复杂等离子体实验中研究了车道形成的动力学开始。小微粒被驱动并渗透到大颗粒云中，显示出形成泳道的强烈趋势。所观察到的时间分辨车道形成过程是在良好的协议与计算机模拟的二元汤川模型与朗之万动力学。量化的各向异性标度指数，导致一个通用的序参量驱动系统的方面的拉宁。
英文摘要：
The dynamical onset of lane formation is studied in experiments with binary complex plasmas under microgravity conditions. Small microparticles are driven and penetrate into a cloud of big particles, revealing a strong tendency towards lane formation. The observed time-resolved lane formation process is in good agreement with computer simulations of a binary Yukawa model with Langevin dynamics. The laning is quantified in terms of the anisotropic scaling index, leading to a universal order parameter for driven systems.
