摘　　要：周培源湍流理论代表了我国在国际湍流研究中对湍流本质具有独特思想并被广泛应用的学派,但疏于系统整理和进一步研究.本文简要介绍他的湍流理论在揭示湍流本质中的主要成果,及其在气动声学、混沌动力学和空气动力学中的重大应用,以及对他在湍流研究中的贡献做出合理的科学评价.Zhou PeiYuan＇s theories of turbulence represent a chinese school with extinct idea on the nature of turbulence with wide applications in international turbulent researches, but lack of better understanding and further researches. In this paper a brief overview is provided on the main achievement of these theories in discovering the nature of turbulence and its most important applications in aeroacoustics, dynamics of chaos and aerodynamics, in order to give a reasonable scientific evaluation on his contributions in turbulent researches.
