本文从非平衡态统计的一般理论出发,系统地讨论了宏观体系中波对弛豫过程的影响,特别是关联函数的非指数型渐近行为。 由于表象选择对处理耗散过程的重要性,我们必须从元激发表象出发(而不是自由粒子表象)计算关联函数或输运系数(久保公式)。为此,应用了C代数的基本概念,发展了一套算子展开的方法,用之将流算子在元激发二次量子化表象中一般地表示出来。我们从刘维算子的预解式出发,对元激发间的剩余相互作用作微扰,应用了投影算子方法后,可以比较简单地得到关联函数非指数衰减部分的一般表达式。 根据对元激发处理过程的分析,我们将元激发间的剩余相互作用分为两类。对于纯耗散模,考虑线性相互作用后,即得到非指数衰减的主要部分(t~(-d/2)项)。仔细分析表明,非线性作用(模模耦合)是比较小的,而且导致较快的衰减(t~(-d)型),因而可以忽略。 本文还强调指出,对于波过程来说,局部涨落关联,粒子自关联以及输运过程(总粒子流,总热流的关联)有本质的不同,它们的相对大小(指对相应准粒子贡献部分)也可能差别较大。 应用这些一般的结果,我们简单分析了流体情况,并对模耦合理论作了一些讨论。
