随着轨道交通装备行业智能升级,创新人才需求明显提高,生产实习作为实践教学的重要环节,是高校育人目标对接社会人才需求的必要途径。传统教学模式难以适应新背景,在媒介、形式、评价等方面欠缺普适性与针对性。为此,基于生产实习教学实际,提出一种虚实交互的混合教学模式,依托新媒体技术,联动多场景虚拟基地、多区域现实基地,提出延续性强、覆盖面广、稳定性高的5G时代实践教学新方案。实践证明,该方案育人成效更佳,为生产实习教学改革提供了新思路。

作者： han Li-kun JIANG Ya-dong LI Wei CAI Yuan State Key Laboratory of Electronic Thin Film and Integrated Devices School of Opto-Electronic Information University of Electronic Science and Technology of China Chengdu 610054 China

A novel second-order nonlinear optical chromophore （DCDHF-2-V） was synthesized from 3-Hydroxy-3-methyl-2-butanae, propanedinitrile and 4-diethylaminobenzaldehyde by aldol condensation reaction. Molecular structural characterization was investigated by elemental analysis, FTIR, and 1H-NMR spectra. The melting point obtained from DSC thermogram was almost 251 ℃, and the compound shows a thermal stability up to 270 ℃. Second-order NLO properties of the chromophore were measured by solvatochromic method. From the quantum-mechanical two-level model, it can be obtained that the μgβ value of DCDHF-2-V is 6520×10^-48esu atthe wavelength of 1064 nm.
