考虑了惠更斯薄波前在湍流介质中传播的动力学。推导出了与波前面积成正比的有效速度\(v_{F}\)的严格渐近表达式。结果表明，波前位置的小尺度涨落具有很强的间歇性。这种间歇性在确定波前速度的稳态大小方面起着关键作用。将结果与实验数据进行了比较。
The dynamics of a thin Huygens front propagating through turbulent medium is considered. A rigorous asymptotic expression for the effective velocity $v_{F}$ proportional to the front area is derived. The small-scale fluctuations of the front position are shown to be strongly intermittent. This intermittency plays a crucial role in establishing a steady state magnitude of the front velocity. The results are compared with experimental data.
