该院大学生目前的体质健康状况越来越受社会关注的社会问题,同时大学生存在体质的个体差别大的情况。但是就其原因是更多的学生并不是不健康,更多的学生是处于一个健康与不健康的中间状态即亚健康状态。对于解决亚健康状态有很多的锻炼方式可以加以解决,可是就运动本身来说都要承受一定的运动负荷,不一定适合每一个人,因此,体育工作者急需找到一个可以参与度更高的项目运动来缓解目前学生的亚健康状态。  相似文献

大学生亚健康状态的心理因素分析   总被引:1,自引:0,他引:1  
亚健康是指人体介于健康与疾病之间的一种临界状态.国内学者调查研究发现,我国高校大学生的亚健康状态已经到了不容忽视的境况.除生活习惯、周围环境等因素外,心理状态也是导致大学生身体亚健康状态的重要因素之一,本文主要从大学生的压力、抗压能力、心理调控能力、人生观因素及人格障碍等方面对此进行了阐述,并且对健康教育提出了有针对性的建议,以期改变目前大学生的亚健康状态,改善大学生的健康状况.  相似文献

探究广东省2009-2019年的生态系统健康时空动态变化特征,可为广东省社会经济与生态系统健康可持续发展提供数据支持与理论参考。本文基于VOR模型耦合生态服务系统价值并采用最小二乘法优化组合赋权方法构建新的多指标评价体系,对广东省2009-2019年的生态系统健康状况进行评价与分析。结果表明:(1)广东省近11年来生态系统健康状况整体处于二级亚健康及以下水平,呈现北部内陆地区优于南部沿海地区的空间分布特征;(2) )广东省近11年来生态系统健康等级变化主要在二级和三级之间相互转化,生态系统健康等级为二级的区域面积占比呈现起伏状态。处于二级亚健康水平的区域面积占比在2015年、2016年和2018年高达50%以上,生态系统健康状况最好;而2009-2011年以及2019年处于二级亚健康水平的区域面积占比不到30%,生态系统健康状况有变差的趋势。(3)广东省在2009-2019年间生态系统健康状况处于改善的区域面积比退化的区域高4.79%,但2014-2019年间相较于2009-2014年间生态系统健康等级退化的区域面积占比上升23.05%,生态系统健康状况在2014-2019年间出现明显恶化,呈现由二级亚健康水平向三级一般健康水平转化趋势。研究结果从时间和空间上定量分析 2009-2019 年广东省生态系统健康状况,根据南北地区生态系统健康状况差异提出相应政策建议,对推动广东省生态文明建设协调发展具有实际意义。  相似文献

北仑河口近岸海域生态健康分析与评价   总被引:1,自引:0,他引:1       下载免费PDF全文
【目的】对北仑河口近岸海域生态环境质量现状进行分析,评价该海域的生态系统健康状况。【方法】根据2011年11月对广西北仑河口近岸海域海洋的调查结果,采用《近岸海洋生态健康评价指南》中的河口及海湾生态系统健康评价方法对该海域的生态系统健康状况进行分析与评价。【结果】水环境健康指数、沉积环境健康指数、生物残毒健康指数、栖息地健康指数、生物健康指数分别为11.73、10.00、9.00、10.00、14.24,海域生态系统健康指数为54.97。表明,北仑河口近岸海域水环境和沉积环境都处于健康状态,未受生物残毒污染,而栖息地和生物指标分别处于亚健康和不健康状态;虽然水环境判定为健康状态,但其健康指数已接近亚健康标准阈值,且已呈现富营养化。【结论】综合5类评价因子的评价结果,判定北仑河口近岸海域的生态环境处于亚健康状态。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that  相似文献
