本文首先從靜態的角度來分析消費者權益受到損害的原因。通過分析發現，單純地依靠政府的力量來打擊不法經營者、維護消費者合法權益的作用是有限的，短期中經營者會因為政府加大打擊力度而收斂自己的行為，但政府由於受經費等資源的限制，不可能長期堅持下去。從另一個角度，如果鼓勵消費者維護自身的合法權益，則經營者侵權行為發生的概率會降低，而且具有持久性。We will regularize the equations by the standard mollifier to get the approximate solutions. then by making uniform estimates to the approximate solutions and by passing to the limit, we obtain the local existence for the above problem. then, based on the local existence of the classical solution, we discuss the blow - up criterion
