学术不端文献检测系统的检测盲区研究

学术不端文献检测系统是世界反学术不端行为的一把利器。但是系统的智能程度不高,经常会出现检测盲区,因此期刊编辑不能简单、机械地依据文字复制比的高低来判断来稿能否通过初审,而应根据系统的检测结果,发挥主观能动性,并借助多种手段来作判断,保证期刊的学术质量和学术水平。     

"数学物理方法"课程建设的设想和实践

新形势下，“数学物理方法”仍然是理科(非数学系)的重要数学基础课。但需要精选经典内容，适当溶入现代的观点和方法，分出层次，以适应不同的需求。在实施中，以思想统方法，以理解、应用为重点，不求全面，留有空间。鼓励学生提出问题和解决问题，而教师要研究改进考核方法。

Influence of regression model and initial intensity of an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and running performance

Abstract

This study investigated the influence of the regression model and initial intensity during an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and performance in elite-standard runners. Twenty-three well-trained runners completed a discontinuous incremental running test on a treadmill. Speed started at 9 km · h^?1 and increased by 1.5 km · h^?1 every 4 min until exhaustion, with a minute of recovery for blood collection. Lactate–speed data were fitted by exponential and polynomial models. The lactate threshold was determined for both models, using all the co-ordinates, excluding the first and excluding the first and second points. The exponential lactate threshold was greater than the polynomial equivalent in any co-ordinate condition (P < 0.001). For both models, the lactate threshold was lower when all co-ordinates were used than when the first and the first and second points were excluded (P < 0.001). 10-km race pace was correlated with both the exponential and polynomial lactate thresholds for all the co-ordinate conditions (r ≥ 0.75, P < 0.001 and r ≥ 0.56, P < 0.05, respectively). The results suggest that the exponential lactate threshold should be used instead of the polynomial equivalent since it is more strongly associated with performance and is independent of the initial intensity of the test.     

中国科技创新-产业升级协同度综合测度

基于复合系统协同度模型,实证分析了2000—2015年中国科技创新-产业升级相同基期和相邻基期协同度。结果表明:2001—2015年中国科技创新-产业升级相同基期协同度显著提升,但科技创新系统有序度一直低于产业升级系统有序度,是制约相同基期协同度提升的关键;2001—2015年中国科技创新-产业升级相邻基期协同度在[0.014,0.089]之间,处于低度协同演变状态;科技创新与产业升级平衡发展更能促进复合系统相同基期协同度提高,即发挥"2×2>3×1"的整体协同效应,也更能促进复合系统相邻基期协同度稳定演变。

Dynamic properties of composite cemented clay

In this work,the dynamic properties of composite cemented clay under a wide range of strains were studied considering the effect of different mixing ratio and the change of confining pressures through dynamic triaxial test. A simple and practical method to estimate the dynamic elastic modulus and damping ratio is proposed in this paper and a related empirical normalized formula is also presented. The results provide useful guidelines for preliminary estimation of cement requirements to improve the dynamic properties of clays.     

任务驱动教学法在“药理学”实验教学中的应用

基于“药理学”课程实验与任务教学法的特点,设计将任务驱动教学法用于“药理学”实验教学的方案,包括创设情境、明确任务,必要知识讲解,学生实验完成任务,任务评价、教学反馈共4个步骤,并将其用于教学实践。调查问卷结果表明,学生的学习体验较好,获得感强,实验积极性较高,对该教学法总体上比较满意。任务驱动教学法在实验教学中具有对客观条件要求低、符合实验动物伦理学、培养学生责任心等优势。     

我国中小学生师比与平均班额解悖分析——从我国与部分OECD国家的比较角度

为解决我国中小学生师比与平均班额之间存在的"悖论",通过与部分OECD国家进行比较,发现我国教育经费投入严重不足、教师工作量过大、学生课业负担较重、教育规划布局不尽合理这四个方面,是导致我国中小学生师比与平均班额反常发展、班级规模居高不下的重要原因。
