关于体育课结构的重新认识

从体育课的特点出发讨论了体育课的宏观结构和微观结构。由于体育课是一个教学过程而不同训练过程，因而其宏观结构必须突出知识和技术学习的主线，其大致可分为五个阶段或者部分，即引导阶段、学习知识和技术阶段、巩固知识和技术阶段、检查评价阶段和结束阶段。此外，体育课的微观结构与课的目的、类型及教学对象特点等因素有关，故在安排每堂体育课的结构时绝不能千篇一律。     

全章目录学辨

Quan Zuwang and Zhang Xuecheng were both bibliognosts of Qing Dynasty. In Quan s theory of bibliography, there is neither the connotation of enlightenment thought nor the ideological content of, what is called the Yi Wen Xue An in Zhang s bibliographical thinking, which, together with his literary and historical thinking has reciprocal outward show and inner thought. He had founded the theory of new bibliography and developed a school of his own. It s true that his theory carries on the theories of his predecessors and those of the same generation of him,but it is by no means the product of "being very close"to any of theirs.     

划水板流体动力特征的风洞实验研究

本文介绍了自行研制的三种划水板和国外两种划水板及其在风洞内进行的测力实验,以了解分析其不同的流体动力特征;对板面开孔与无孔吹风测力、板面有或无稳流板条及板条分布的测试结果,为新型划水板的设计提供了理论依据。研究发现,螺旋曲面扭转结构的自制板对运动员手掌最佳对水倾斜角有诱导修正作用,能帮助运动员建立良好的技术,提高“水感”,获得理想的划水效果。实验结果表明以上观点是可以肯定的。

从汶川大地震谈加强灾难档案研究的重要意义

2008年5月12日,汶川大地震一场巨大的灾难袭击了四川汶川,让几万中华儿女在地震中蒙难,举国哀思那些在灾难中离去的逝者。突如其来的自然灾害难以避免,但是,通过档案研究一个地区的灾难史,吸取经验教训,减少灾难的发生,是非常必要的。     

转变思想观念加快竞体发展

本文从理论的高度,论述了当今我国竞技体育必须随着经济体制的变革而变革。体制的转变,首先是思想观念的转变：转变指导思想,变＂办＂为＂管＂;转变思维方式。变＂要＂为＂找＂;克服教条思想,打破金牌＂至上＂。     

Lighting the Shroud of Turin for Exhibition in 2015

ABSTRACT

Lighting a cultural heritage artifact requires balancing visual perception with preventive conservation, by providing the best lighting (in terms of spectral distribution and quantity) to enable the viewer to appreciate details and color, while limiting photo-induced degradation. The paper outlines the methodology applied by a multi-disciplinary team while lighting the Shroud of Turin at its last public exhibition in 2015. The methodology considered the special requirements of the Shroud, including exposure to ultraviolet light, while providing appropriate display conditions that would meet audience expectations. The desired appearance (readability of the body image and color) was defined with the help of Shroud researchers and confirmed by subjective tests, while appropriate light levels for preservation were set in agreement with standard requirements and using knowledge of the degradation of linen in visible and UV light. The installation provided a controlled environment and a managed visitor route to the Shroud, assuring excellent perception of both details and color, with the lowest illuminance level about 15?lx.
