We first prove that quenching always occurs. Then, by considering the initial value problem, we prove the existence of globally monotone decreasing solutions by a shooting method. Finally, we study the asymptotic behavior of any globally monotone decreasing solution.擬線性拋物型方程自我相似解消失性投射法漸近行為quasilinear parabolic equationself-similar solutionsquenchingshooting methodasymptotic behavior
