越南胡志明市田径教练员训练观念现状与对策研究

胡志明市田径运动项目曾经是越南田径的一面旗帜,是胡志明市体育运动的骄傲。但是这些年来,胡志明市田径队的成绩一直下降,影响到胡志明市体育事业的整体发展乃至越南田径运动项目的发展。当一个运动项目的发展长期停滞不前的时候,首先要反思的就是训练观念。这不仅是训练观念正确与否而是判断它的先进程度。有一些对运动训练有着很大指导作用的观念,但随着时间的推移对目前的训练实践可能已经不具有指导意义,他们正确但不先进。本人运用文献资料法、实践研究法、问卷调查法、数理统计法和逻辑分析法对胡志明市田径教练员训练观念进行研究分析,研究结果：训练观念是在运动训练的理论知识和实践认识的基础上对运动项目的本质特点、制胜规律及发展趋势、组织实施训练和比赛活动的一种思想和看法等,它的主要内容是确立训练指导思想,构建训练目标和制定训练计划等。训练观念具有地理性、稳定性、可变性和联接性等特点。训练观念是训练理论与实践的桥梁,是反映训练主体对训练客观与实践规律的认识,它从认识实践规律中得出各种手段和办法,进行改造客体的身心、形态。它解决训练中“为什么练”,“练什么”,“怎么练”,“练多少”的重要问题。胡志明市田径教练员年龄结构比较合理,大多数教练员都曾经是优秀运动员并有较高的运动经历,教练员学历层次、职称相对较高,也有比较丰富的执教经历。但是,大部分教练员都来源于退役运动员,因此,训练理论知识的掌握都存在“嫁接”、“拿来”的现象,训练目的的盲目性大,缺少科学理论支撑,训练科技含量低,以经验训练为主,学历文凭与实际执教能力有一定的差距。胡志明市田径教练员训练观念停留在传统的分期训练理论框架之下。由于越南国内体育竞赛体制的局限性,教练员参加比赛的机会很少尤其是国际比赛,对当今竞技体育发展新动向不了解,导致训练观念落后与陈旧,直接影响了在训练实践过程中训练内容针对性不强,训练安排、训练方法手段理解和掌握不正确,盲目性大,缺乏创新。加上长期以来,教练员缺乏业务培训、专业进修及其它接受新知识的机会少,从而影响到了胡志明市田径运动成绩的提高。为了改变当前胡志明市田径教练员训练观念陈旧的这种格局,不断提高胡志明市田径运动技术水平,必须转变训练观念,在训练实践中运动负荷的安排做到适量高质;训练内容、方法要有用有效;训练计划结构要合理、科学有节奏。即要以人为本、以专项为核心、以高强度为主导。有计划、系统的加强教练员业务能力的培训,定期组织各级教练员训练工作交流会议,提高认识能力和理论知识水平及执教能力。加强科学选材和青少年后备人才的培养。加强后勤保障措施建设,保证运动员的训练条件、管理制度、医疗服务、饮食住宿、文化教育等工作。希望通过探讨研究国内外田径训练的先进观念、训练方法的同时,从中找出胡志明市田径训练存在的不足,提出改变局限的对策,以达到不断提高胡志明市田径队竞技水平,促进越南田径运动的健康发展。

对外汉语教材中存在已久的同译词现象,对外国人习得汉语影响很大。针对英语版注释的汉语教材中的同译词研究已经取得了一些成果,但对越南语注释的汉语教材中同译词的研究资料却很少。为此,本文以越南语注释的汉语教材中同译动词作为目标分析对象,在胡志明市师范大学学生汉语作业中搜集相关语料,对越南学生的使用情况进行考察,并对这些同译动词进行系统研究。本文通过定量统计和定性分析相结合、语际比较及偏误分析等研究方法,将几套越南语注释的汉语教材中的同译动词进行统计、筛选和分类,考察分析越南人使用这些同译词的偏误情况,并提出在汉语教材和工具书的编写中应该如何处理同译词,教师在实际教学中又该如何处理同译词才能取得最好的教学效果。希望通过本文的探讨,能丰富针对越南学生的汉语词汇习得研究,进而为对越汉语词汇教学、教材编写以及词典编纂提供有价值的参考。

The δ18O and δ2H stable isotope techniques for studying properties of groundwater and surface help us to understand more clearly about the distribution and movement of groundwater in the South of Hanoi area. There were 68 water samples from the studying area and analyzed by a Liquid Water Isotope Analyzer (LWIA-24D). The stable isotope values of the groundwater from Pleistocene aquifers were range from -3.21‰ to -9.55‰ δ18O and -35.32‰ to -67.44‰ δ2H;rainwater from -8.18‰ to -4.13‰ δ18O and -61.19‰ to -17.93‰ δ2H;Red river water from -7.51‰ to -5.29‰ δ18O and -51.60‰ to -38.99‰ δ2H. Based on stable isotope characteristics, the results show that there was a relationship between surface water and groundwater in the South of Hanoi city. It is that groundwater recharges for river water in the dry season with 74%, and in the rainfall season groundwater is recharged from river with 87%.

客套话是语言交际中重要的内容。本文从中越两国文化对比出发,分析了汉语与越南语文化中客套话的异同。二者在交际中相同的地方较多,比如语用中的观念、礼仪等,主要差异是打招呼、告别、时间表达等方面,这是由文化和历史原因造成的。因... 详细信息

客套话是语言交际中重要的内容。本文从中越两国文化对比出发,分析了汉语与越南语文化中客套话的异同。二者在交际中相同的地方较多,比如语用中的观念、礼仪等,主要差异是打招呼、告别、时间表达等方面,这是由文化和历史原因造成的。因此,对于越南学生来说,学习汉语客套话在形式上、语用中就存在一定难度,对此,本文通过分析常见客套话学习中容易出现的偏误,给出教学建议,探讨了关于礼仪、宗教、历史、时代等因素引发的教学问题,提出了如对照学习、固定对话等教学方法,希望能够帮助越南学生能够较好地应用汉语客套语进行交际,避免跨文化交际中的障碍。

Vinyl ester (VE) resin inherently has intrinsic brittleness due to its high cross-link density. To improve mechanical performance, micro/nano fillers are widely used to modify this matrix. In present study, glass fiber in submicron scale at low contents was added into VE to prepare submicron composite (sMC). The impact resistance of un-notched sMC degraded with the increase of sGF content while that of notched-sMC remained the unchanged. Flexural properties of sMCs also were the same with that of neat resin. The results of Dynamic mechanical analysis (DMA) test showed the slight increase of storage modulus and the decrease of tan delta value in the case of sMC compared to those of un-filled matrix. However, the Mode I fracture toughness of sMC improved up to 26% and 61% corresponding to 0.3 and 0.6 wt% glass fiber used. The compact tension sample test suggests that there is the delay of crack propagation under tensile cyclic load in resin reinforced by submicron glass fiber. The number of failure cycle enlarged proportionally with the increment of sGF content in matrix.
