吸附在表面的环形聚合物中，切向活性与排除体积相互作用的相互影响，始终导致环形构型的整体膨胀。这与三维线性和环形聚合物的情况形成强烈对比，在后者中活性常常导致结构坍塌。通过布朗动力学模拟，我们研究了如何通过一个与活性相关的弗洛里指数来普遍表征这种活性环的标度性质，这是对平衡行为的一种推广。在高活性下，一个有效的持久长度表征了活性柔性环的构象。
英文摘要
The interplay of tangential activity and excluded-volume interactions in ring polymers adsorbed to a surface, consistently results in the overall swelling of the ring configurations. This is in strong contrast to the case for three dimensional linear and ring polymers, where activity induces frequently collapsed structures. By means of Brownian Dynamic simulations, we investigate how the scaling properties of such active rings can be universally characterized by an activity-dependent Flory exponent, as a generalization of the equilibrium behavior. At high activity, an effective persistence length characterizes the conformations of active flexible rings.
