摘要 We study capillary spreadings of thin films of liquids of power-law rheology. These satisfy ut+(u^λ+2|uxxx|^λ-1uxxx)x=0,where u (x, t) represents the thickness of the one-dimensional liquid and λ 〉 1. We look for traveling wave solutions so that u(x,t) =g(x+ct) and thus g satisfies g'''=|g-ε|^1/λ/g^1+2/λ sgn(g-ε) We show that for each ε 〉 0 there is an infinitely oscillating solution, gε, such that limt→∞ gε=ε and that gε→ g0 as ε → O, where g0≡ 0 for t ≥ 0 and g0=cλ|t|3λ/2λ+1 for t〈0 for some constant cλ.
