利用Kruskal简化方法证明了氢链中带Φ4位势的质子运动动力学方程的Painlevé性质,并借助tanh与coth方法给出该方程的若干精确行波解.
The dynamical equation with φ4 potential of proton in hydrogen-bonded systems is proved to possess the Painlevé property in the sense of Kruskal simplification.Some new exact travelling wave solutions of the equation are also obtained by using the tanh and coth methods.
