此词条暂由彩云小译翻译，未经人工整理和审校，带来阅读不便，请见谅。In [[applied physics]], the concept of '''controlling self-organized criticality''' refers to the control of processes by which a [[self-organized]] system dissipates [[energy]]. The objective of the control is to reduce the probability of occurrence of and size of [[energy dissipation]] bursts, often called ''avalanches'', of self-organized systems. Dissipation of energy in a [[self-organized criticality|self-organized critical]] system into a lower energy state can be costly for society, since it depends on avalanches of all sizes usually following a kind of [[power law]] distribution and large avalanches can be damaging and disruptive.<ref name=cajand10a>{{cite journal

在应用物理学中，控制自组织临界性的概念是指控制自组织系统消耗能量的过程。这种控制的目的是减少自组织系统发生能量耗散爆发(通常称为雪崩)的概率和规模。将一个自我组织的临界系统中的能量耗散到较低的能量状态对社会来说可能是代价高昂的，因为它依赖于各种规模的雪崩，这些雪崩通常遵循一种幂律分布，大规模雪崩可能具有破坏性和破坏性。 10a { cite journal

#'' Dynamically modifying the local thresholds of cascading failures.'' In a model of an electric transmission network, Heiko Hoffmann and David W. Payton demonstrated that either randomly upgrading lines (sort of like preventive maintenance) or upgrading broken lines to a random breakage threshold suppresses self-organized criticality.<ref name=hh2014>{{cite journal

The failure cascades in electrical transmission and financial sectors occur because economic forces cause these systems to operate near a critical point, where avalanches of indeterminate size become possible.

发生电力传输和金融部门的故障级联是因为经济力量使这些系统在临界点附近运行，在那里可能发生规模不确定的雪崩。
