In this study,the Pauli blocking potential between two colliding nuclei in the density overlapping region is applied to describe the heavy nuclei fusion process.Inspired by the Pauli blocking effect in the α-decay of heavy nuclei,the Pauli blocking potential of single nucleon from the surrounding matter is obtained.In fusion reactions with strong density overlap,the Pauli blocking potential between the projectile and target can be constructed using a single folding model.By considering this potential,the double folding model with a new parameter set is employed to analyze the fusion processes of 95 systems.A wider Coulomb barrier and shallower potential pocket are formed in the inner part of the potential between the two colliding nuclei,compared to that calculated using the Akyüz-Win-ther potential.The fusion hindrance phenomena at deep sub-barrier energies are described well for fusion systems 16O + 208Pb and 58Ni + 58Ni.

In this study,the heavy to heavy decay of B0s → D*+D-is evaluated through the factorization approach by using the final state interaction as an effective correction.Under the factorization approach,this decay mode oc-curs only through the annihilation pro
中华优秀传统文化是我国文化自信的坚实基础,承载着中华民族最深沉的精神追求,丰富的人生哲理与深邃的优秀思想对唤醒大学生职业生涯规划意识和进行“职业探索”具有极高思想引领价值.该文以大学生引用的先贤古人名言警句来分析优秀传统文化在职业生涯规划中的影响,并进行课程教学的融合探索.
The isospin dependence of spin-orbit (SO) splitting becomes increasingly important as N/Z increases in neutron-rich nuclei.Following the initial independent-particle strategy toward explaining the occurrence of magic numbers,we systematically investigated
体态语作为非语言交际的一个重要分支,在交际中传递着许多信息.尤其是在跨文化交际中,能够起到强调、补充、替代、辅助感性与理性信息传递的作用.由于非语言交际具有模糊性和文化规约性,所以不同民族的仪态举止、表情眼神和动作也就体现了其特殊的地理环境、文化背景等.该文从课堂礼仪类和教学辅助类的体态语出发,对比分析了中意体态语差异.根据差异进行成因分析,并针对分析结果对跨文化交际下的体态语在对外汉语课堂教学中的应用进行总结反思并提出应用建议.
Cross sections of the 58,60,61Ni(n,α)55,57,58Fe reactions were measured at 8.50,9.50 and 10.50 MeV neut-ron energies based on the HI-13 tandem accelerator of China Institute of Atomic Energy (CIAE) with enriched 58Ni,60Ni,and 61Ni foil samples with backin
MCN是网络参与式文化经UGC到PUGC之后的最新发展趋势,也是近年来社会各界开始广泛关注的研究领域.它是原有的传统大众文化生产结构和体系被解构之后,出现的一个具有高度专业生产能力、经济整合能力的新的中介,新的文化生态将围绕它建构起新的文化经济体系,因而是当下最为显著重要的文化场域,未来研究需要对此场域中MCN、个体内容生产者、平台、资本各方之间的互动关系和结构展开更为深入和具体的研究,以此深化对新文化生态体系的核心理论探讨.
In our previous work[Phys.Rev.C 101,014003 (2020)],the photoproduction reaction γp → K*+Λ was investigated within an effective Lagrangian approach.The reaction amplitudes were constructed by including the t-channel K,K*,and κ exchanges,u-channel Λ,∑,and ∑
为了推进双方的文化交流,并进一步增强优秀中国文化在葡萄牙,乃至葡语国家的有效传播,有必要深入研究葡萄牙的文化惯例以及价值观等方面.该研究分析在“一带一路”视域下,中国文化与葡萄牙文化的差异与融合,以海洋、足球和美食文化为切入点,浅析中葡文化各自的内涵和特点,探讨中国文化“走出去”在葡语国家的实践路径.
为降低自然界随机噪声对地电场数据的干扰,在数据可视化表达的过程中,采用合理的数字滤波技术是提升对兴趣异常可靠识别的重要手段,但如何寻求最优化的插值及滤波方法成为数据处理的关键.以小型水库渗漏探测为例,考虑到大坝硬化、游离电流以及系统噪声等的随机干扰,从图像的视角分析了不同插值技术的差异性,并提出对网格化数据进行滤波处理,探讨了滤波方法、网格大小以及迭代次数对成图的影响.结果表明,自然邻点法和克里金法,较适合土石坝隐患的电阻率成像;低通滤波技术能有效压制随机噪声的干扰,提高图像的平滑度;不同的滤波技术具有一
南充作为川陕红军革命根据地的重要拼图,孕育了朱德元帅、罗瑞卿大将、民主革命家张澜和共产主义战士张思德等伟大革命先辈.作为南充文化核心组成部分的南充红色文化是彰显城市形象和内涵的重要载体.在国家“文化走出去”战略大背景下,南充红色旅游文化外宣方兴未艾.以生态翻译学为理论基础,探析如何从“语言维”“文化维”“交际维”3个维度提升南充红色旅游文化外宣翻译质量,以便更好地助推南充红色文化“走出去”,提升城市文化软实力,构建城市良好国际形象.
