At present,the analytic tools used for the power signals in microcomputer protection include FFT,Kalman filter and finitely shock response filter,etc.They are effective to analyze stationary signals but localizable for unstationary signals analysis.Especially it is difficult to identify nonlinear fault,e.g,the nonlinear high impedance short trouble is along-term unsolved problem of power system.

目前，用于微机保护中的电力信号分析工具有FFT、Kalman滤波器、有限冲激响应滤波器等，它们对于平稳信号的分析是高效的，但在分析非平稳信号中有其局限性；尤其对非线性故障识别困难，如探测高阻抗非线性短路故障便是电力系统一个长期没有很好解决的问题。

Because violated has been wrongly sentenced three year American criminals, in was near leaves prison the eve, wrote a letter to the wife, in the letter expressed own because of not to have finitely to as the husband, as father's responsibility felt the deep regret and the apology, in were filled with the anticipation to be able to go home, the family could again his at the same time, also confessed for violated has been wrong, did not have the qualifications request family to admit him, therefore, his extreme hope knew, if the wife still loved him, still in waited for him to go home, then on tied a yellow ribbon on the village old oak tree; If he cannot see the yellow ribbon on the tree, he also understood wife's regard, he will continue to ride in a carriage goes far away.

一个因犯了错误被判刑三年的美国犯人，在临出狱前夕，给妻子写了封信，信中表达了自己因没有尽到作为丈夫、作为父亲的责任而感到深深的悔与歉意，在满心期待能回家，家庭能重新他的同时，又自认为犯了错，没有资格要求家庭接纳他，因此，他极度的期盼知道，如果妻子依然爱他，仍在等他回家，那么就在村口的老橡树上系上一条黄丝带；如果他在树上看不见黄丝带，他也明白妻子的心意，他将继续乘车远去。

Some nonexistence results for p-degenerate sub-elliptic first order evolution inequalities associated with the generalized Baouendi-Grushin vector fields are given. The method is an improvement of the admissible function method in Euclidean space. The proof hardly depends on the properties of the generalized Baouendi-Grushin vector fields.

通过改进欧氏的容许函数法，应用广义Baouendi-Grushin向量场的一些性质，选取特殊的容许函数，利用Hlder不等式和Young不等式，证明了由广义Baouendi-Grushin向量场构成的p-退化次椭圆一阶发展不等方程，在适当条件下非平凡弱解的不存在性。
