简介：Basil and Henry are all aesthetes respectively representing Oscar Wilde’s aestheticism in their own way. The protagonist Dorian Gray is a youth with stunning beauty,he made a confession to Lord Henry about the influence of Dorian’s beauty upon his art as,is not only a picture in which Wilde’s aestheticism is faithfully painted

简介：a dandy and cynic who treats life as a spectator sport and exercises a malign influence upon Dorian. It is through his scintillating remarks that Oscar Wilde finds an ideal outlet for his own outlook toward art and life. In Lord Henry three elements coalesce to distinguish Wilde as a leading aesthete,paradoxes like these cast a spell upon readers throughout the pages. Lord Henry’s use of paradoxes would be less disturbing for readers if it were a style that Wilde had applied solely to depict an obviously corrupt character within the novel. But paradox is the hallmark of Wilde’s own style of speaking in his real life,when Lord Henry speaks. To highlight Lord Henry’s demeanor and habit as a dandy

简介：研究了具Neumann边界条件的Gray—Scott模型非常值正稳态解的不存在性。首先，借助于极值原理、Harnack不等式和先验估计技巧，得到了正解的上、下界；其次，利用积分平均方法，推导出了一个新的积分恒等式；最后，利用上述结果并结合Poincar6不等式，给出了不存在非常值正解的若干充分条件。
