两等同双能级原子与三模腔场任意多光子共振相互作用辐射谱的一般特征

本文研究了两个偶极——偶极力关联的等同双能级原子与三模腔场间任意多光于共振相互作用的辐射谱。对三模腔场分别处于不同数态:即三模均为真空场、三模均为强场、一模为真空场两模为强场以及两模为真空场一模为强场时辐射谱的结构特征及物理特性进行了详细分析,从而揭示出“三模腔场——两原子系统”的多光子辐射谱的一般特征。

柳宗元与界围岩

元和十年(815)正月,柳宗元奉诏北上,写上<界围岩水帘>诗,五月赴任柳州,写有<再至界围岩水帘遂宿岩下>诗,陶醉于人间仙境,没有流露出哀怨之音,成为柳诗创作中的一个特殊现象.     

Student perceptions of successful learning support for an international high school programme: a comparative case study in Turkey

Abstract

This study used comparative case study methodology to investigate student perceptions of different programmes that prepare them for a challenging high school education programme: the International Baccalaureate Diploma Programme (IBDP). Given the benefits and challenges of the programme, educators and stakeholders want to ensure students feel ready to participate. In the literature, studies support that programmes such as the International General Certificate of Secondary Education and the International Baccalaureate Organisation’s Middle Years Programme prepare students for the IBDP; however, there is a need for students’ voices on how they perceive they are prepared through these programmes. This study investigated three different approaches to IBDP preparation by gaining student insights through a scaled-item questionnaire and interviews. Students identified experiences that gave them skills to monitor their learning and resources that motivated them to participate in an advanced upper-high school programme.     

略论两汉时期的禁锢

禁锢是指对犯罪者取消为官资格。禁锢在春秋时期就已出现,两汉尤其东汉时期发展为朝廷镇压士人的手段之一,且禁锢的范围有所扩大。禁锢打击了士人入仕的积极性,削弱了王朝的政治生命力。     

以庆元廊桥民间文学为例看民间文学之价值

民间文学是一种与文人作家之书面文学有区别的“立体性”文学,它是民众生活经验、审美情趣和文化情境的文学表现形式,有着自己的实用价值和审美价值。全文以庆元廊桥的民间文学为例,探讨民间文学的实用价值和审美价值。     

高校舞蹈欣赏课的思考

舞蹈欣赏课与舞蹈专业的教育不尽相同。如何充分发挥这门课程在培养大学生综合能力方面的特殊功能,需要教师从开设这门课程的必要性上进行认真、深入的探索和研究,提出合理的建议。     

社会主义中国化的最早形态——论孙中山三大政策的民生主义

孙中山“联俄、联共、扶助农工”三大政策的新三民主义是社会主义中国化的最早形态。联俄 ,走社会主义道路 ;联共 ,干社会主义事业 ;扶助农工 ,唤醒社会主义的力量。三大政策导致了孙中山革命实践与理论的三大转折 :把学习榜样从西方资本主义转向了东方的苏俄社会主义 ;把革命联合力量由大军阀、大资本家转向了中国共产党 ;把革命基本动力由资产阶级转向了工农民众。三大根本性转变使得孙中山的社会主义由主观变成现实。中国的具体国情与发展阶段的历史定位是孙中山三大政策的民生主义成为现实的客观基础与理论依据。只有从孙中山三大政策的民生主义的时代特征与中国特点去理解与认识其社会主义 ,对孙中山晚年的评价才可能是客观和公允的。     

再论垣曲诸冯山是帝舜故里

《孟子》记载“舜生于诸冯,迁于负夏,卒于鸣条,东夷之人也”,“舜之居深山之中”。《史记》认为,“舜,冀州之人也。舜耕历山,渔雷泽,陶河滨,作什器于寿丘,就时于负夏。”这两者相互补充,相辅相成。结合现实的遗迹遗址、民间传说、考古证据和史籍记载,我们得出了“垣曲诸冯山是帝舜故里”这个观点。其实,这种观点早在三百多年前,顾祖禹在《读史方舆纪要》中已经提出,也已载入国家典籍《古今图书集成》。     

Spontaneous recovery and ABC renewal from retroactive cue interference

Two conditioned suppression experiments with rats were conducted to determine whether the spontaneous recovery and renewal that are commonly observed in retroactive outcome interference (e.g., extinction) also occur in retroactive cue interference. Experiment 1 showed that a long delay between Phase 2 (the interfering phase) and testing produces a recovery from the cue interference (i.e., the delay enhanced responding to the target cue trained in Phase 1), which is analogous to the spontaneous recovery effect observed in extinction and other retroactive outcome interference procedures. Experiment 2 showed that, when target and interfering cues are trained in separate contexts and testing occurs in a different but familiar context, a recovery from the cue interference is also observed (i.e., the context shift enhanced responding to the target), which is analogous to ABC renewal from extinction. The results are discussed in terms of the possibility that similar associative mechanisms underlie cue and outcome interference.
