查菲 - 堙方特方程（Chaffee-Infante equation）是一个非线性偏微分方程：

u_{t}-u_{xx}+\lambda*(u^3-u)=0

解析解
:u(x, t) = -1/2-(1/2I)cot(_C1-(1/4)\sqrt(-2\lambda)x+(3/4I)\lambdat)
:u(x, t) = -1/2-(1/2I)tan(_C1-(1/4)\sqrt(-2\lambda)x-(3/4I)\lambdat)
:u(x, t) = -1/2+(1/2I)cot(_C1+(1/4)\sqrt(-2\lambda)x-(3/4I)\lambdat)
:u(x, t) = -1/2+(1/2I)tan(_C1+(1/4)\sqrt(-2\lambda)x+(3/4I)\lambdat)
:u(x, t) = -1/2-(1/2)coth(_C1-(1/4)\sqrt(2)\sqrt(\lambda)x+(3/4)\lambdat)
:u(x, t) = -1/2+(1/2)tanh(_C1-(1/4)\sqrt(2)\sqrt(\lambda)x-(3/4)\lambdat)
:u(x, t) = 1/2-(1/2I)cot(_C1-(1/4)\sqrt(-2\lambda)x-(3/4I)\lambdat)
:u(x, t) = 1/2-(1/2I)tan(_C1+(1/4)\sqrt(-2\lambda)x+(3/4I)\lambdat)
:u(x, t) = 1/2-(1/2)coth(_C1-(1/4)\sqrt(2)\sqrt(\lambda)x-(3/4)\lambdat)
