研究了具有取向依赖相互作用的定向聚合物的二维缠绕角。利用精确的解析计算、计算机模拟和现象学论证，我们成功地找到了大部分相图中绕组角的变化。我们的结果表明，缠绕角分布是一个普适量，并且$ heta$-点是膨胀相、法向坍缩相和螺旋坍缩相之间的三相边界相交的点。正常塌缩相和螺旋相之间的转变是连续的。
We study winding angles of oriented polymers with orientation-dependent interaction in two dimensions. Using exact analytical calculations, computer simulations, and phenomenological arguments, we succeed in finding the variance of the winding angle for most of the phase diagram. Our results suggest that the winding angle distribution is a universal quantity, and that the $ heta$--point is the point where the three phase boundaries between the swollen, the normal collapsed, and the spiral collapsed phase meet. The transition between the normal collapsed phase and the spiral phase is shown to be continuous.
