This paper is a continuation of the previous paper in the Joual of Partial Differential Equations [1]. We derive in this paper the renormalized energy to furthe
In this paper we study the initial boundary value problem of GBBM equations on unbounded domain ut - △ut = divf(u)u(x, 0) = u0(x)and corresponding Cauchy probl
In this paper the upwind discontinuous Galerkin methods with triangle meshes for two dimensional neutron transport equations will be studied.The stability for b
海伦·托马斯是美国新闻界一位引人注目的女性。在1972年尼克松访华时庞大的随行记者团中,她是唯一的女士;在白宫的总统记者招待会结束时,也通常由她站起来说:“谢谢,总统先
In this paper, we study the spectral asymptotic behavior for a class of Schr dinger operators on 1-dimensional fractal domains. We have obtained, if the potenti
土壤盐渍化是世界范围内影响作物产量的主要非生物胁迫因子之一,也是农作物减产的主要原因之一。相当大的一部分农作物品种因受不同程度盐害的影响难以发挥其增产和优质潜力。据统计,影响作物产量的各种环境因素中,干旱和盐碱造成的减产在40%以上。如何提高植物的耐盐性成为当前一个迫切需要解决的科学问题。小麦是世界上种植面积最大的粮食作物,全球有1/3以上的人口以小麦为主要粮食。发展小麦生产,对满足人民的粮食需求

穗发芽(Preharvest sprouting, PHS)是指种子收获前在母体植株上萌发的一种现象,作为世界性的生理性病害,穗发芽对作物产量、品质、贮藏及种子质量均有严重影响,是生产中亟待解决的难题。近年来,玉米穗发芽的发生对自交系的选育、杂交组配应用和杂交一代种的制种生产造成了一定的影响,给玉米生产带来了较大的损失,有必要对其展开深入的研究。本研究以弱休眠玉米自交系A318为材料,利用Affy
The existence of the attractors of the periodic initial value problem for the Landau-Lifshitz-Maxwell equations in one and two space dimensions is proved. We al
