考虑了一类含奇异项的退缩抛物型方程组柯西问题解的存在性与初始条件的关系,证明了当初值较大时解会在有限时刻产生猝灭的现象,在初值较小时解是全局存在的。
攷慮瞭一類含奇異項的退縮拋物型方程組柯西問題解的存在性與初始條件的關繫,證明瞭噹初值較大時解會在有限時刻產生猝滅的現象,在初值較小時解是全跼存在的。

T he relation about the existences of solutions and initial conditions for Cauchy problem of a sin-gular and degenerate parabolic systems has been studied in this paper .It is proved that in large initial con-dition the solutions quench in a finite time and in small initial condition the solutions exist globally .
