研究了随机驱动的具有猝灭无序的守恒Kardar-Parisi-Zhang（CKPZ）方程.发现短程猝灭无序是一维纯CKPZ方程的相关扰动，因此出现了不同于纯CKPZ方程的不同普适类。在更高的维度，淬火无序原来是无效的影响普遍的标度。这导致由线性理论给出的渐近长波长标度，与纯CKPZ方程相同的情况。对于足够长范围的淬灭无序，即使在更高的维度上，普遍标度也会受到淬灭无序的影响。
We study the stochastically driven conserved Kardar-Parisi-Zhang (CKPZ) equation with quenched disorders. Short-ranged quenched disorders are found to be a relevant perturbation on the pure CKPZ equation at one dimension and, as a result, a different universality class different from pure CKPZ equation appears to emerge. At higher dimensions, quenched disorder turns out to be ineffective to influence the universal scaling. This results in the asymptotic long wavelength scaling to be given by the linear theory, a scenario identical with the pure CKPZ equation. For sufficiently long-ranged quenched disorders, the universal scaling is impacted by the quenched disorder even at higher dimensions.
