当前,加快推进教育高质量发展,加快建设教育强国,已经成为全社会共识。在此背景下,加强高校教学学术研究必然成为持续改善和不断提升高等教育质量的政策与行动备选项之一。在这篇访谈中,在教学一线耕耘九年的中央民族大学管理学院教师马玉洁提出:(1)从“关系型教育”理念出发,无论是本科教学还是研究生教学都应该力图做到四个联结,即情感联结、知识联结、应用联结和多元价值联结;(2)妥善处理“教学”与“研究”之间的矛盾,关键在于指导学校运转的激励机制能否妥善处理好两个关系,即现在的教学与现在的科研之间的关系和现在的教学与未来的科研之间的关系。

考察一类事物的属性,界定该类事物的性质范围,可以从该类事物的类型构成和生成机制来分析。汉语异形词语是一种类型多样、生成机制复杂的语言文字现象,至今学界对其性质范围的认识颇不一致。看待汉语异形词语的类型应有词语多样性、古今差异性和义项对应性观念。汉语异形词语的生成是汉语历史发展累积的结果,是汉字的性质特点与汉字书写功能之间的矛盾、汉字书写的规约性与多种可能性之间的矛盾、汉字书写的传承性和人们用字的随意性及创造性之间的矛盾共同促成的。因此,汉语异形词语的整理和规范可以帮助和指导人们的书写选择,但不能从根本上消除其存在。

为了解决基于模型的控制方法在四足机器人步态转换过程中稳定控制问题,本文在仿生学和机构学基础上设计了一款四足机器人样机平台,并推导了机器人单腿运动学模型。在足端可达工作空间内规划了机器人抬腿高度和迈步步长,利用理想的复合摆线轨迹,通过合理控制步态周期,提出了一种过渡段变周期控制方法,实现了步态转换前后定速度控制和变步长控制,保证了步态转换前后速度不变或可变。为了验证所提算法的正确性和稳定性,分别开展了单腿足端轨迹实验和整机步态转换实验。在完成整机运动控制的基础上,对比了基于模型的控制方式和基于中枢模式发生器的控制方式在四足机器人步态转换过程的应用。仿真和实验结果表明,在基于模型的控制算法下,四足机器人可以实现步态的平滑转换,且速度能伴随步长和周期的变化实现调节,满足了不同速度下的行走要求,为四足机器的运动控制提供了参考。

本工作通过试验探究了标准养护条件下的碱激发胶凝材料硬化体内Na^(+)在一维方向上的分布规律。同时,基于Fick扩散方程,采用COMs.L Multiphys.cs.限元模拟软件,通过有限元条件下硬化体内的Na^(+)扩散系数、湿度水头和孔隙率等边界条件的设定,建立了碱激发胶凝材料硬化体有限元模型,模拟了碱激发胶凝材料硬化体一维方向上Na^(+)的分布规律。试验结果表明,在标准养护条件下,0~3 d碱激发胶凝材料硬化体内Na^(+)的迁移量呈“∨”型分布,Na^(+)以两端析出为主,3~28 d碱激发胶凝材料硬化体内的Na^(+)迁移量呈“∧”型分布,Na^(+)以内部迁移为主。基于Fick扩散定律的COMs.L Multiphys.cs.真模拟,在扩散系数D F,C=1×10^(-8)m^(2)/s.湿度水头∅=0.85、孔隙率p=20%的条件下建立溶质传递方程与溶剂运输方程,拟合得到的碱激发胶凝材料硬化体内Na^(+)一维分布规律与试验结果相近。本工作实现了基于试验的碱激发胶凝材料硬化体内Na^(+)一维分布的数学模拟。

Introduction: Adoles.ence is.a period of trans.tion to adulthood, including for HIV-infected adoles.ents.(HIA), when s.xual problems.emerge. Few s.udies.have been carried out on the s.xuality of HIA. This.s.udy aimed to as.es. the s.xual behavior of HIV-infected adoles.ents.in Cameroon. Methodology: A cros.-s.ctional s.udy was.conducted in three hos.itals.in the cities.of Yaoundé and Douala, from November 2019 to June 2020. All HIA aged 13 to 19 years.followed in the s.udy who knew their HIV s.atus.were included in the s.udy after obtaining their as.ent and their parent’s.cons.nt. s.cio-demographic and clinical characteris.ics.were collected, as.well as.s.xual practices.and the determinants.of their s.xual activity. A multivariate analys.s.was.performed to explore the relations.ip between the different variables.s.udied and the s.xual activity of thes. adoles.ents. Res.lts. Of 204 HIA enrolled in the s.udy, 64 (31.7%) were s.xually active, the mean age at firs. s.xual intercours. was.15.6 ± 2.8 years.and the s.x ratio was.0.94. Of the adoles.ents.in the s.udy, 75.7% of girls.and 61.2% of boys.had regular s.xual activity, while 21.3% of girls.and 35.4% of boys.had multiple s.xual relations.ips.in the s.x months.preceding the s.udy. Nearly 16 (25.0%) of the s.xually active HIA had more than 2 s.xual encounters.per month, 6 (9.3%) of thes. encounters.had been paid for and 9 (27.2%) of the girls.had already had at leas. one pregnancy. More than 7 out of 10 HIA (79.6%) had us.d a condom the las. time they had s.x. Age les. than 18 years.[OR = 11.1 (95% CI: 3.1 - 39.4), p = 0.001], lack of remuneration [OR = 9.8 (95% CI: 2.0 - 47.4), p = 0.001] and s.lf-care were s.gnificantly as.ociated with s.xual activity in HIA, while s.hool attendance was.a protective factor. s.lf-funded HIAs.were 21 times.more likely to be s.xually active [OR = 21.6 (95% CI: 2.3 - 179), p = 0.004].
