Abstract ：
密立根油滴实验是大学物理实验中的重要课程。实验中学生通过宏观的力学研究微观世界的量子性，能够培养学生的动手能力自主学习能力、对已有知识的综合运用能力、组织协调能力。然而教学中存在实验样本少、实验流程长、“试错”选择性筛选结果等问题。本文通过分析教学成果，探讨了教学过程中存在的缺陷，并提出对教学设备进行改进的方案：使用机器视觉来改进密立根油滴实验的流程，实时图像处理和自动化数据收集，学生可以更专注于实验的理论和结果分析，而不是繁琐的操作过程。这样的系统还可以使实验结果更易于分享和讨论，增加互动性，从而提高学生的学习积极性和吸收效果。不仅可以提高教学质量，还可以激发学生的兴趣，培养他们的科学素养和创新能力。这是教育技术发展的一个重要方向，值得探索和实施。

Abstract ：
Pancharatnam Berry (PB) phase optical elements can manipulate local polarization state of light in the cross-sectional plane by addressing an additional PB phase relating to the orientation of the optical axis of the waveplate-like structure. However, chromatic aberration including spectrum-dependent retardation and diffraction efficiency limits their applications in the field of visible broadband imaging and display. In this article, the chromatic aberration of a liquid crystal (LC) PB phase lens was measured by a home-built RGB full -Stokes imaging polarimeter. The chirality conversion efficiency and depolarization at RGB wavelengths can be calculated from the measured Stokes vectors. Our experiments show that even the spectrum-dependent retar-dation exists, the measured PB phase lens has a uniform and high diffraction efficiency in the visible band. Affected by the local LC molecule, the input polarization of RGB light was rotated in varying degrees, but the focusing or defocusing manipulation to the right-or left-hand circular polarization, originated from the PB phase, results in fixed focal lengths for different colors. Our experiments show that the LC-based PB phase lens is suitable for the visible broadband applications.

Abstract ：
在简谐振动实验中,通过改变滑块的质量测量不同质量滑块的振动周期.文章用Origin软件对实验数据进行线性拟合,得到滑块质量与振动周期平方的关系曲线的斜率及截距大小,从而能够准确的计算出弹簧有效质量的大小.实验结果表明,对于轻质弹簧而言,弹簧的有效质量是其质量的1/3,实验误差主要是受滑块的黏滞阻力、空气阻力及弹簧受重力的影响.

Abstract ：
Fluorescence fluctuation-based superresolution techniques can achieve fast superresolution imaging on a costeffective wide-field platform at a low light level with reduced phototoxicity. However, the current methods exhibit certain imaging deficiencies that misinterpret nanoscale features reconstructed from fluctuating image sequences, thus degrading the superresolution imaging quality and performance. Here we propose cross-cumulant enhanced radiality nanoscopy (CERN), which employs cross-cumulant analysis in tandem with radiality processing. We demonstrated that CERN can significantly improve the spatial resolution at a low light level while eliminating the misinterpretations of nanoscale features of the existing fluctuation-based superresolution methods. In the experiment, we further verified the superior performance of CERN over the current methods through performing multicolor superresolution imaging of subcellular microtubule networks and clathrin-coated pits as well as the high-precision reconstruction of densely packed RNA transcripts.

Abstract ：
A full-Stokes polarization imaging method was introduced by using a liquid crystal variable retarder (LCVR) and the metallic nanograting arrays. The linear polarization was detected based on the dichroic transmission of the metallic nanograting. The circular polarization was retrieved from two successive measurements with different retardance or orientation of LCVR. The determinant of data retrieve matrix was analyzed for the LCVR optimization. A full-Stokes imaging setup was built, calibrated, and proof-of-principle verified through imaging of radially polarized beams.

Abstract ：
Sensitivity as an important personality, there is currently no unified definition of psychology. There has been a lot of debate about related research. This study uses literature analysis and questionnaire survey methods to explore three dimensions of sensitivity: "Perceptual Sensitivity", "Emotional Sensitivity", "Volitional Sensitivity", and sensitivity is defined as A personality trait that is "highly alert to external information, easy to obtain clues, and has a higher ability to perceive subtle changes." Study 2 explored the relationship between sensitivity and Emotional Intelligence, and found that sensitivity and emotional intelligence were significantly positively correlated when individuals with higher levels of mental health.
