We study theoretically the interracial electronic property of a heterojunction made from two Mott insulators (MI)with different magnetic structures.By means of
This paper investigates the dynamical behaviour of the Liu system with time delayed feedback.Two typical situations are considered and the effect of time-delay
Based on a calculation model, we study the interference phenomena of serially coupled V-type and A-type triple quantum dots (CTQDs) driven simultaneously by a s
Halo structure is added to sub-100 nm surrounding-gate metal--oxide-semiconductor field- effect-transistors (MOSFETs) to suppress short channel effect.This pape
We have studied the cyclotron-resonance absorption and photoluminescence properties of the modulation n-doped ZnSe/BeTe/ZnSe type-Ⅱ quantum wells. It is shown
一、露冷莲房坠粉红八大山人,原名朱耷(1626一1705),字雪个、号个山,后更号人屋、驴、个山驴、八大山人等,江西南昌人,是明朝皇帝朱元璋之子宁献王朱权的第九代孙。入清后隐
Considering such a fact that travellers dynamically adjust their routes and the resultant link traffic flows in a network evolve over time,this paper proposes a
采用化学共沉淀法制备了稀土Ce/SnO_2光催化剂,以XRD、SEM等测试手段对其进行晶型、粒径、形貌等的表征。催化剂为四方晶系金红石结构,平均粒径在40~50 nm之间。在可见光条件
近年来由于双季稻(包括迟熟粳稻)面积和水稻轻简化栽培面积不断扩大,水稻成熟期推迟,稻油茬口矛盾加剧,晚稻收获后种植下茬油菜难以获得较高产量,导致目前长江流域冬闲田面积累计已超过600万hm2。在双季稻区采用稻田套播油菜栽培模式,可以提前油菜播种期、有效缓解稻油茬口矛盾,充分利用温光资源,提高复种指数、增加油菜产量,因而是利用我国南方双季稻区冬闲田的有效手段。目前,稻田套播油菜栽培模式在湖北、江苏、
