We have calculated the relaxation time of a cruciform structure in superhelical DNA as a function of the superhelix density for palindromic regions of different lengths. The relaxation time has a sharp maximum at the superhelix density which corresponds to the equilibrium transition point between the cruciform structure and the regular double helix. This maximal value is shown to depend dramatically on the length of the palindromic region.
我们计算了超螺旋DNA中十字形结构的弛豫时间，该弛豫时间是不同长度回文区域超螺旋密度的函数。弛豫时间在超螺旋密度处有一个尖锐的最大值，该超螺旋密度对应于十字形结构与规则双螺旋之间的平衡转变点。结果表明，这个最大值显著取决于回文区域的长度。
