A comprehensive review of weak decays of charmed hadrons (D0/+,Ds+ and Ac+) based on analyses of the threshold data from e+e-annihilation in the BESⅢ experiment is presented.Current experimental challenges and successes in understanding decays of the charmed hadrons are discussed.Precise calibrations of quantum chromodynamics and tests of the standard model are provided by measurements of purely leptonic and semi-leptonic decays of charmed hadrons,and lepton universality is probed in purely leptonic decays of charmed mesons to three generations ofleptons.Quantum correlations in threshold data samples provide access to strong phases in the neutral D meson decays and probe the decay dynamics of the charmed Ac baryon.Charm physics studies with near-threshold production of charmed particle pairs are unique to BESⅢ,and provide many important opportunities and challenges.

近年来,随着《国务院关于印发国家职业教育改革实施方案的通知》《国家教育事业发展“十三五”规划》《教育信息化2.0行动计划》等文件的出台,现代化教育事业发展逐渐提上日程.互联网作为当下大学英语教师教学工作开展的重要辅助工具,不仅改变了以往的教学架构,唤醒学生学习热情,而且在多元化的教学资源与教学手段的引导下,能够促进学生英语综合能力的提升.基于此,文章以培养学生交际能力为例,以互联网环境为教学改革的突破口,从其应用价值入手,提出具体渗透策略,以期为广大教育学者提供有价值的借鉴.
在医学专业研究生英语教学中,可根据教学主题,融合学术英语、医学英语和人文思政英语,多模态设计课程思政教学活动.系列教学活动的设计,应围绕教学主题,从输入到输出活动,从逻辑思维到创造性思维的培养,由易到难,层层递进,兼顾学生综合应用英语的能力、学术能力和职业道德素养的培养.
本研究通过对天津某高校6名大学英语教师进行访谈,得出以下结论:多数教师缺乏对思辨能力的系统性认识;对思辨评价方式及标准了解不够深入;教师不仅有提升自身思辨能力的需求,也需要行之有效的方法.为此,文章从学院层面和教师个人层面提出了针对大学英语教师的思辨能力培养策略.
本研究主要探讨图形组织器对学生内容与语言整合性学习(简称CLIL)课堂中阅读能力发展的影响.学生现阶段学习存在英语阅读理解能力以及阅读策略不足的问题.解决这个问题的策略可以使用图形组织器以及参与和其他主题相关的方式方法.使用图形组织器促进有意义学习,是连接读者从文本中引出的先前信息和新信息的有效工具.即使学习者从未接受过CLIL的相关指导,但能有效通过图形组织器克服困难.因此,CLIL环境中使用图形组织器是提高英语阅读的有效方法.

Hadron spectroscopy provides a way to understand the dynamics of the strong interaction.For light hadron systems,only phenomenological models or lattice quantum chromodynamics (QCD) are applicable,because of the failure of perturbation expansions for QCD
Studies of light meson decays are important tools to perform precision tests of the effective field theories,determine transition form factors and test fundamental symmetries.With very high statistics data samples,the Beijing Spectrometer Ⅲ (BESⅢ) experim

Charmonium is a bound state of a charmed quark and a charmed antiquark,and a charmoniumlike state is a resonant structure that contains a charmed quark and antiquark pair but has properties that are incompatible with a conventional charmonium state.While
