多元文化视角:中外合作办学批判性课程文化的生成与构建

在中外合作办学的人才培养过程中,课程的重要性不言而喻,其最大的特点便是合作双方课程的融合或衔接所带来的“文化多元性“。这种多元的文化让学生有了丰富的体验与思考,但多种文化的冲突也使课程的目标、内容、实施面临一定的困境。因此,在这种特点下,合作办学模式下的课程应形成一种具有批判性特色的课程文化,培养出能够将所学知识灵活运用、举一反三、具有辩证意识的创新性人才,最终达到引进优质教育资源的目的

Features of applying acupoints in clinic of Chengjiang School descendant CHEN Ying-long

澄江学派传人陈应龙先生是闽南近现代著名针灸医家,其在临床上注重穴位的选取与运用,强调经络是针灸的物质基础,而穴位是治疗疾病和保健的要枢。其临床取; 穴特色主要表现为:引经据典,精简取穴;注重经络,循经取穴;辨证施治,审因取穴;调理久病,轮流取穴。CHEN Ying-long, a descendant of the Chengjiang School, is a famous; modern acupuncture and moxibustion doctor in Minnan. He focuses on the; selection and application of acupuncture points, emphasizing the; meridian is the material basis of acupuncture, and believes that; acupuncture points is the pivot of disease treatment and health care.; The clinical characteristics of acupoints mainly include selecting the; acupoints according to classical literatures, selecting the acupoints; according to the channel, selecting the acupoints according to the; pathogenesis, and selecting acupoints according by turns

戊型肝炎诊断、预防及治疗新进展

戊型肝炎由HEV感染导致,是全球最主要的病毒性肝炎之一。传统的观念认为戊型肝炎只流行于发展中国家,而随着研究的逐步深入,人们已经认识到戊型肝炎是一种分布于全球并能带来严重负担的疾病。近年来,随着可靠的诊断试剂和戊型肝炎疫苗的成功上市,相关研究及防控进入了一个新时代

科学对待疫苗接种后不良事件

疫苗是延长人类平均寿命最有力的工具之一.脊髓灰质炎等多种传染病的发病率和死亡率,是目疫苗的应用成功地从地球上消灭了天花,显著降低前控制传染性疾病最有效的措施之一[1].广泛接种疫苗带来的健康效益,不论对群体或个体而言都是毋庸置疑的.然而,疫苗的发展史也伴随着悲剧:在19世纪晚期,使用神经组织细胞生产的狂犬疫苗预防了大量死亡,但每接种230人中就有1人出现癫痫、麻痹和/或昏迷[2];1942年,数十万美军士兵接种了包含人血清的黄热病疫苗,由于部分人血清中携带乙肝

The Modern Research and Application of Pueraria Flower Liquor-Resolving Decoction

酒在社会生活中扮演了极其重要的角色,其中酗酒和酒精中毒者也随之增多,成为危害身体健康的一大因素。葛花解酲汤作为千古解酒名方之一,受到众多相关人士的重视,被加以广泛研究运用。本文探讨了葛花解酲汤目前的研究与应用现状,为今后的相关实验研究提供依据。Wine plays a very important role in social life.There has been a rise in excessive drinking and alcoholism,which is bad for health.Pueraria Flower Liquor-Resolving Decoction,as one of the most famous prescriptions of alleviating Hangover,is paid more attention to and widely studied by related people.In order to provide the basis for future related research,we discuss the current experiment and application situation of Pueraria Flower Liquor-Resolving Decoction in this paper

Investigation of behaviour of particle impact on material by impinging jet

颗粒冲击材料现象广泛存在于自然界以及工业领域中。应用实验测量与数值计算相结合的方法研究了颗粒射流冲击材料(304不锈钢)的磨损行为。考虑了颗粒粒; 径、运动轨迹、颗粒-壁面撞击点分布以及所导致材料物相结构变化。实验测试包括材料质量损耗、材料元素X射线衍射(XRD)分析、表面微观结构扫描电镜(; SEM)观察。对相应的颗粒射流冲击材料行为进行了数值计算,获得流场,颗粒场以及相应材料磨损。结果表明:颗粒射流冲击下颗粒运动轨迹与撞击点的分布不; 同,造成了材料样品表面磨损区域明显不同。颗粒-壁面碰撞不仅会导致材料损失而且会造成材料物相结构的变化。Particle-material impact is popular in the nature and industries. In; this work, experimental measurement and numerical calculation were; carried out to investigate the particle impinging jet effect on the; behaviour of material (304 stainless steel). Herein, particle diameter,; particle tracking trajectories, particle-wall collision point; distribution were considered to study material loss and the phase change; of material structure. In the experimental work, the measurements were; carried out for material mass loss, material element X-ray; diffractometry (XRD) analysis, surface micro-structure scanning electron; microscopy (SEM) observation and so on. In addition, the behaviour of; particle impinging jet impact on wall material was studied by numerical; simulations. Particularly, flow fields, particle trajectories and wall; material loss were obtained. The results show that particle collision; point distribution is quite different from their tracking trajectories; under particle impinging jet impact, which causes the wear zones on; sample surface different from each other obviously. It is concluded that; particle-wall impact will not only lead to material loss but also cause; the phase change of material structure.国家自然科学基
