| 摘 要： | 通过对湍流层次结构模型中提出的最高激发态的进一步研究发现，最高激发态
存在绝对标度律，且该绝对标度律是由信号中最强耗散涨落的局部结构产生的，并由此推测
出局部强间歇结构一般具有绝对标度的结论.

| Abstract: | In this paper, the most intensive structure proposed first
in Hierarchical-Structure (H-S) model is further studied, and it is
concluded that there exists an absolute scaling law for this structure,
and the statistical absolute scaling behavior is only produced by the local and
strong intermittence structure. In a statistical theory, it is essential
to consider the local fluid structures, especially, the strong intensive
structures. |

| Keywords: | turbulence the most intensive structure absolute scaling law |
