高等院校公共体育课程思政推进探究

为提升高等院校公共体育课程思政教学成效,研究运用文献资料、逻辑分析等方法,对高校公共体育课程思政推进展开探讨。高校公共体育课程思政的实施具有促进学生知识技能与思想境界双重提升、推动课程创新、提升教学质量和落实立德树人教育目标的价值意蕴,但目前在实施过程中存在教学品质不高、教师能力亟待提高和学生积极性不高等问题。在分析构建高质量教学内容、完善师资水平和营造良好教育环境推进着力点的基础上,提出加强课程设计、提升教学品质、强化教师能力、提升教育水平和重视学生需求、提升学习积极性等推进策略。

中空全固态Z型异质结光催化剂的研究进展

中空结构材料由于比表面积大、密度低和电荷传输距离短等特点,在光催化反应中具有巨大的应用价值. Z型光催化剂具有宽光谱响应、高稳定性、高光生载流子的分离效率以及强氧化还原能力等优点,受到了广泛关注.然而,由于Z型多元组分和中空结构不稳定,设计并制备高效稳定的中空全固态Z型光催化剂仍是一大挑战.本文综合评述了近年来中空全固态Z型光催化剂的种类、构筑策略及性能等方面的研究进展,并进一步展望了其在未来应用中面临的问题与挑战,最后归纳总结了其设计与发展方向,为高效稳定光催化剂的设计提供了思路.

疫情防控档案资源建设与智能决策咨询能力建设研究

Competitive Adsorption of Anticorrosion and Antiwear Additives

Simulated adsorptive experiments using the axletree and lubricating oil containing anticorrosion additive were conducted,and the UV absorbance of the lubricating oil before and after the adsorptive experiments was measured.Through the UV spectral measurements the difference in UV absorbance of the lubricating oil before and after the adsorptive experiments was identified,the adsorbed quantity of anticorrosion additive in the interfacial film between lubricating oil and bearing was calculated using the Lambert-Bell principle to verify the adsorption of corrosion inhibitor on the surface of friction pairs.Adsorption experiments on lubricating oil containing both antiwear and anticorrosion additives were carried out and the UV absorbance of lubricating oil samples before and after the experiments was measured to determine the difference in the UV absorbance among lubricating oil samples with the same mass fraction of anticorrosion additive and different mass fractions of antiwear additive.By measuring the ultraviolet spectral absorbance of lubricating oil samples and calculating the adsorbed quantity of anticorrosion additive in the interfacial film it was possible to determine the influence of antiwear additive on the quantity of adsorbed anticorrosion additive on the surface of friction pairs and verify the competitive adsorption relationship between the antiwear additive and the anticorrosion additive.
