摘要 对直接约化理论在处理方法上作了相应的推广,将其用于变系数KdV方程的约化,得到的常微分方程可以自由选择一个参数Γ3(z)来决定约化的形式,其结果较直接约化理论得到的结果更丰富;此外,得到的可约化变系数KdV方程对系数的限制条件更具有一般性,这有助于相关物理问题的研究。 The manipulation of the direct similarity reduction method (presented by Clarkson and Kruskal (CK method)) is improved, and then applied to a variable coefficients KdV equation. More similarity reductions were obtained. Simultaneity the restriction, which is against the coefficients of the vcKdV that obtained from consistent condition, is more general.
