摘要
本文利用Gurtin的方法讨论均匀流动中激浪的破碎问题,得到了波阵面斜率的控制方程。求解该方程,得到了破碎位置的显式表达式及破碎位置和均匀流速的关系。当均匀流速为零时,就化为Gurtin所得的结果。
In this paper, Gurtin's method is used to discuss the breaking of a bore in anuniform current. An equation governing the slope of the wave front is derivedfirst, then the equation is solved and an explicit expression of the breaking positionis obtained. It is shown that the breaking position relates to the uniform currentvielocity, which reduces to the result obtained by Gurtin when the uniform currentvanishes.
