给出了求解可积非线性演化方程qt-2(1/√1+q)xxx=0的逆散射方法。证明了一个新的可积非线性演化方程rt+(1-r)3rxxx=0具有奇异尖形孤子解（尖孤子），该方程可转化为上述方程。
Inverse scattering method for the already found integrable nonlinear evolution equationqt-2(1/ √1+q)xxx=0 is presented. A new integrable nonlinear evolution equationrt+(1-r)3rxxx=0, which can be transformed into the above-mentioned equation, is shown to have a singular spiky soliton solution (cusp soliton).
