平直界面一维晶体生长问题的相似解

对于平直界面下由过冷边界开始的熔体的一维凝固过程，考虑液态中远场温度高于凝固温度，而底板温度低于凝固温度，利用相似性解法分别求解固液态温度，分析其结果，说明由低温区长入高温区的界面总是稳定的，从而更加完善了一维晶体生长理论．

A new pedagogical model for adventure in the curriculum: part one – advocating for the model

Background: In recent years increasing attention has been given to models-based approaches to physical education as a way of promoting standards and particular types of learning through better alignment of teacher planning and delivery with pupil learning and achievement. However, little attention has been given to the specific contribution a pedagogical model for outdoor adventure education (OAE) has to make to pupils learning.

Purpose: This paper is presented in two parts. Part one is an advocacy paper and draws upon the broader discourse around models-based practice to make a case for the development of a pedagogical model for OAE. Drawing upon guidelines for models-based approaches to physical education, this paper considers the theoretical foundation, rationale, review of research findings and major theme that inform the development of a model of OAE.

Conclusions: The selected review of the research suggests that the major impact of OAE is upon the affective domain, particularly in relation to pupils developing a positive self-concept. Learning is also evident in the cognitive and physical domains, but this is secondary to learning in the affective domain. Drawing upon the analysis of the research literature, the major theme for the model is identified as ‘personal growth through adventure’ and ‘OAE’ is suggested as the name of the model. Part two of this paper builds upon these foundations to outline what a pedagogical model for OAE might look like in a secondary school in the UK.     

Neuromuscular and technical abilities related to age in water-polo players

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s^?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.     

蔬菜栽培课程产学合作教育的实践与思考

选择具有日光温室、塑料大棚、中棚及露地等多种生产方式，蔬菜种类较多，面积较大，种植蔬菜历史较长，交通便利的村寨作为蔬菜栽培课程产学合作教育的基地。把学生分配到农户，每户3～4名学生为一组，与蔬菜生产实际紧密结合，让学生接受培养土的配制，种子处理与播种，苗床管理，定植，田间管理及嫁接育苗等环节的训练。结果表明：学生获得了两个层面的训练。在第一个层面上，学生熟练掌握了蔬菜栽培基本环节的技术要求和要领，动手能力得到明显提高，培养了学生的基本技能；在第二个层面上，学生掌握了蔬菜设施栽培、无公害生产综合配套等高层次技术，培养了学生综合技术应用能力。今后应特别注意学生和生产者(企业或农户)的双向参与，信息的双向传递，学校与生产者(或企业或农户)双赢，以及培养学生创新能力即第三个层面的训练。     

黑龙江省冰雪装备制造业创新成长影响要素与战略研究

随着我国成功申办2022年冬奥会,我国将大力发展冰雪运动,并会随之带动旅游、经济和冰雪装备制造业的发展。而冰雪装备制造业的发展直接影响我国冰雪体育事业的开展。采用文献资料、调查、系统分析等研究方法,针对黑龙江省冰雪装备制造业的创新成长问题进行研究,并对黑龙江省的冰雪装备制造业创新成长影响要素以及企业创新成长存在的问题进行分析与总结,认为黑龙江省冰雪装备制造业创新成长的总体状况是良好的,但企业存在资金短缺,经营、管理、技术等方面人才匮乏,企业产品结构单一、产品科技创新意识和能力不强,欠缺可持续发展理念等问题。通过分析影响冰雪装备制造业创新成长的原因,提出引进与自我创新相结合、注重品牌质量、发扬政府主导优势等战略,旨为冰雪装备制造业在黑龙江省的发展提供理论依据。     

国际级、国家级篮球裁判员后备人才培养模式研究--“基地式”篮球裁判员培养模式构建研究

运用文献资料、专家访谈、数理统计和逻辑分析等研究方法,对当前篮球裁判员培养方式进行分析研究。针对目前篮球裁判员培养中存在的各种问题,从培养基地的设立依据、目标设置、课程设置、教学设计等方面构建了"基地式"篮球裁判员培养模式。研究结果表明："基地式"篮球裁判员培养模式能充分发挥和利用高校体育院校的篮球裁判后备人才、师资力量、体育场馆设施等资源;采用理论与实践教学相结合的有效培养体系,培养过程科学、合理、系统、规范,培养效果显著,是当前中国篮球裁判员培养方式的有益补充和创新,具有实际可操作性和可行性。建议裁判员管理部门对基地进行培养经费投入,在基地积极组织和承办大型篮球赛事,为裁判员实践学习和临场锻炼提供平台,促进篮球裁判员培养工作持续、快速、有效的发展。
