一类二维三键结构上损伤扩散的平均临界温度

The averaged critical temperature of damage spreading on a kind of two-dimensional trivalent structures

研究微扰源或损伤点取自不同多边形时,对一类二维三键结构上损伤扩散的临界温度的影响.结果表明,损伤点取自不同多边形时,临界温度的区别比较明显.引入平均临界温度来表征网络损伤扩散的临界温度,并计算了增加星-三角代换阶数时3-12、3-6-24、3-6-12-48格子的平均临界温度.计算结果表明,随着星-三角代换阶数的增加,损伤扩散的平均临界温度也随之升高.

The effects of the damage origins on the damage spreading on a kind of two-dimensional trivalent structures were studied with Monte Carlo method. The results showed that critical temperature of damage spreading from different polygons is different obviously. The averaged critical temperature was introduced to character the damage spreading of the structures. It is shown that as the order of the star-triangle transformation increases, the averaged critical temperatures of the structures also increase. Explanations for.the results were presented.
