这一提法解决非线性问题，表面上的边界插值这些要素和影响之间的界限。

This formulation solves the non-linear problem on the surface of the boundary elements and interpolates these effects between these boundaries.

最后我们研究了初始边界值问题。通过数值试验证明，线性正弦波会逐步变为非线性的圆锥型波。

At last an initial-boundary value problem was considered and the numerical experiment demonstrated that the linear sinusoidal wave would successively evolve non-linearly into conoidal wave.
