“课程思政”是高等教育紧跟新时代提出的过程育人、全员育人的新要求。《光学》是高等教育物理学专业学生的必修课程之一,如何将光学课程的专业知识与课程思政相融合实现过程育人和全员育人是本课程面临的新的挑战与机遇。教师应当充分思考和挖掘光学知识内容相关的思政元素,并结合光学教学的特点,将这些思政元素与光学教学相融合,在传授光学专业知识的同时辅以思政教育,在润物细无声中实现知识传授与价值观培养的全员育人的目的。本文以光学课程为载体,依据课程的特点对光学发展过程和光学课程内容中蕴含的思政内容进行了深入挖掘。主要从光学中蕴含的辩证唯物思想、科学探索精神、民族自豪感的案例出发,并运用现代教学方法对这些思政元素内容进行重新塑造,最后在教学过程中进行初步的探索与实践。 相似文献

原子核的形状演化效应是核结构研究的重要基础问题之一。通常认为,A=160质量区的奇A核位于大形变核区域,它们的激发态能谱将呈现出典型的转动激发特征。然而,基于E-GOS曲线方法,发现随着角动量的增加,该质量区奇A核的晕带具有显著地从转动激发演化成为振动激发的形状演化现象。此外,为深入理解原子核形状演化的微观机制,采用Total-Routhian-Surface(TRS)方法针对稀土区的奇A核进行了理论计算,结果表明,165Yb和157Dy同位素在低激发态时具有稳定的长椭形变,当角动量大于0.50 MeV后,核芯的四极形变显著减小并开始产生三轴形变。The phase transition of nuclei with increasing angular momentum (or spin) and excitation energy is one of the most fundamental topics of nuclear structure research. The odd-N nuclei with A ≈160 are widely considered belonging to the well-deformed region, and their excitation spectra are energetically favored to exhibit the rotational characteristics. In this work, however, the evidence suggesting that the nuclei changes from rotation to vibration along the yrast lines as a function of spin was found. The simple method, named as E-Gamma Over Spin (E-GOS) curves, would be used to discern the evolution from rotational to vibrational structure in nuclei for various spin ranges. Meanwhile, in order to understand the band structure properties of nuclei, theoretical calculations have been performed for the yrast bands of the odd-A rare-earth nuclei within the framework of the total routhian surface (TRS) model. The TRS plots predict that the 165Yb and 157Dy isotopes have large quadrupole shapes at low spin states. At higher rotational frequency (hω~ >0.50 MeV), a clear reduction of the quadrupole deformation is indicated by the present results, and the isotopes become rigid in the γ deformation. 相似文献

On the basis of the light nuclear reaction model, a new kerma coefficient formula has been developed. In terms of the analysis for n+^16O reactions below 30 MeV, the average energies of all kinds of the emitted particles are presented. The calculated partial kerma coefficients agree well with the existing experimental data. The discrepancies of the total kerma coefficients between the calculation and the measurement are analyzed in detail. 相似文献

The title compound 5-allyl-2,3-dihydro-9-(2-hydroxy-5-oxocyclopent-1-enyl)-cyclopenta[b]chromen-1(9H)-one monohydrate(C20H18O4.H2O,Mr = 340.36) was synthesized and crystallized.It crystallizes in the triclinic system,space group P with a = 8.5840(17),b = 8.7027(17),c = 11.561(2),α = 89.69(3),β = 74.33(3),γ = 86.13(3)°,V = 829.6(3)3,Z = 2,Dc = 1.363 g/cm3,MoKa radiation(λ = 0.71073 ),F(000) = 360,μ = 0.098 mm-1,the final R = 0.0430 and wR = 0.1008 for 2957 observed reflections with(I > 2σ(I)).X-ray analysis reveals that atoms C(1),C(2),C(3),C(4),C(5) and O(1) on the new pyran ring are coplanar,which is obviously different from the half-chair or boat conformations of other similar compounds. 相似文献

针对当前研究生录取模型中简单依靠数值放大来统一量纲,或依照经验人为确定各考试环节权值的不足,在采用模糊综合评价法将定性信息定量化的基础上,通过传统的层次分析法确定出各影响指标的权重,建立了一种研究生录取的新模型,并设计了有效的录取方案,最后通过实例验证了该方案的合理性. 相似文献
