Free-space quantum key distribution(QKD) plays an important role in the global quantum network. However, free space channels suffer from the atmospheric turbulence and scattering effects of haze,fog, and dust, which significantly weaken the performance of QKD or even block the secure quantum ***, we prove the performance of QKD over a dynamic scattering channel can be enhanced significantly using a fast wavefront shaping technique. The system achieves on average 10-dB enhancement of quantum transmission efficiency and establishes a secure quantum link for QKD. Our work demonstrates the feasibility of QKD through free-space dynamic scattering channels and enhances the deployment capability of complex-channel QKD system.

In an experiment performed on the Shenguang-III prototype laser facility, collective Thomson scattering (TS) is used to study the spatialgrowth of stimulated Brillouin scattering (SBS) in a gas-filled hohlraum by detecting the SBS-driven ion acoustic wave. High-quality timeresolved SBS and TS spectra are obtained simultaneously in the experiment, and these are analyzed by a steady-state code based on theray-tracing model. The analysis indicates that ion–ion collisions may play an important role in suppressing SBS growth in the Au plasma;as aresult, the SBS excited in the filled gas region is dominant. In the early phase of the laser pulse, SBS originates primarily from the high-densityplasma at the edges of the interaction beam channel, which is piled up by the heating of the interaction beam. Throughout the duration of thelaser pulse, the presence of the TS probe beam might mitigate SBS by perturbing the density distribution around the region overlapping withthe interaction beam.

内外之间:庄子德论新诠

作者：苏杭中山大学哲学系

“德”的含义在春秋之后渐趋内向化已成学界共识,这在庄学研究中主要体现为以“德”为“性”,并进而体现为“以天赋论才”和“以不显论不形”。但若细思文义,一方面,《庄子》内篇所论之德固然有内在之义,但所指非“性”,而是对心灵自足... 详细信息

“德”的含义在春秋之后渐趋内向化已成学界共识,这在庄学研究中主要体现为以“德”为“性”,并进而体现为“以天赋论才”和“以不显论不形”。但若细思文义,一方面,《庄子》内篇所论之德固然有内在之义,但所指非“性”,而是对心灵自足状态的摹状;另一方面,“德”的进一步意涵是作为内心自足性的外显。庄子并不将“德”指向伦理心性或内在道德根源,而是将其视作对心与外境一而无分的凸显与伸扬。在这个意义上,庄子论“德”真正贯彻了内外一如的一本原则。

《义务教育艺术课程标准(2022年版)》以“创意实践”为核心素养,对包括音乐学科在内的创造力培养和评价提出了目标和要求。本研究根据韦伯斯特、威廉斯和伯纳德三种测评理论,对如何评测音乐创造力做出了概念界定,并通过德尔菲法和层次分析法构建了音乐创造力测评指标。经过三轮专家意见咨询,最终确定音乐创造力测评指标体系,包括音乐创造性思维、音乐创造性人格和音乐创造性环境3个一级指标,以发散性思维为代表的9个二级指标和以变通性为代表的27个三级指标。权重分布反映出专家对各级指标的重视程度不同,其中思维是专家当前关注的重心。结合新课标对音乐创造力的目标与实践要求,本研究提出:音乐创造力思维的评价应当以三级指标配对的方式进行;人格的评价应采用反思和自评的方式进行;环境的评价可采用量化和质性数据相结合的方式进行。研究结果试图打通长期以来理论到实践的障碍,有助于解决我国基础教育中的音乐创造力评测从概念模型到实践操作的难题,为有效落实新课标中的“创意实践”评测提供了理论基础、设计过程范例和实践方面的参考。
