三维空间中自避游动的扭转是所有有符号交叉点之和在平面上的投影的平均值。我们使用Monte Carlo模拟来计算这个数字。我们的研究结果表明,自回避行走的扭动的绝对值的平均值增加nalpha,其中n是行走的长度和α约=0.5。平均交叉数的步行也计算和发现有一个幂律依赖于步行的长度。此外,我们还考虑了溶剂质量对蠕动和平均交叉步数的影响。
The writhe of a self-avoiding walk in a three-dimensional space is the average over all projections onto a plane of the sum of the signed crossings. We compute this number using a Monte Carlo simulation. Our results suggest that the average of the absolute value of the writhe of self-avoiding walks increases as nalpha , where n is the length of the walks and alpha approximately=0.5. The mean crossing number of walks is also computed and found to have a power-law dependence on the length of the walks. In addition, we consider the effects of solvent quality on the writhe and mean crossing number of walks.
