本文用解析方法导出了稳定分层流体中垂向紊流扩散系数。这种推导不需要已知或指定通量理查森数。将所得的扩散系数表达式与Lilly等人（1974）的平流层结果进行了比较，并讨论了它对大气扩散和晴空湍流的适用性。
Abstract The vertical turbulent diffusion coefficient in a stably stratified fluid is derived analytically. This derivation does not require that the flux Richardson number be known or specified. The resulting expression for the diffusion coefficient is compared with the previous stratospheric results of Lilly et al. (1974) and its applicability to atmospheric diffusion and clear air turbulence is discussed.
