中国近、现代体育思想传承与演变的轨迹与特色

中国近、现代体育思想是在中国进入近、现代社会后中西方体育思想不断融合而产生的,其传承与演变,始终围绕着"健身强国,以实现民族复兴,实现国家的现代化"这样一个主题而展开。中国近、现代体育思想贯穿始终的基本线索有两个:一是传统与现代的碰撞与融合,二是东方与西方的碰撞与融合。这两条线索又始终相生相伴、相互依存、相互缠绕地向前发展着。中国近、现代体育思想的发展既遵循人类思想和体育思想发展的基本规律,同时,又具有其自身的特色。

In the library literature, a great deal of interest in patron-driven collection development has recently been expressed, especially in those programs that link acquisitions with interlibrary loan. However, the implementation of such programs has been limited, at least in part because of concerns over the potential for wasteful spending. The authors will attempt to address this common concern by assessing whether monies spent via a patron-driven acquisitions program were more or less effective than monies spent via traditional modes of acquisition.     

太平军马队述论

太平军当年曾组建过一支庞大的马队,其投入的人(马)数量多时竟达两万余众;在北伐、天京破围战等一系列重大军事行动中,发挥了不可低估的作用,是太平军中一支不可多得的劲旅;太平军马队与清军、湘军在北方大平原、两湖平原、长江中下游平原一带的鏖战冲杀,开创了近代史上敌我双方马队大规模捉对撕杀的先例,在"冷兵器"向"热兵器"过渡时代为步、骑协同作战提供了一系列可资借鉴的战例.

Electro-mechanically controlled assembly of reconfigurable 3D mesostructures and electronic devices based on dielectric elastomer platforms

The manufacture of 3D mesostructures is receiving rapidly increasing attention, because of the fundamental significance and practical applications across wide-ranging areas. The recently developed approach of buckling-guided assembly allows deterministic formation of complex 3D mesostructures in a broad set of functional materials, with feature sizes spanning nanoscale to centimeter-scale. Previous studies mostly exploited mechanically controlled assembly platforms using elastomer substrates, which limits the capabilities to achieve on-demand local assembly, and to reshape assembled mesostructures into distinct 3D configurations. This work introduces a set of design concepts and assembly strategies to utilize dielectric elastomer actuators as powerful platforms for the electro-mechanically controlled 3D assembly. Capabilities of sequential, local loading with desired strain distributions allow access to precisely tailored 3D mesostructures that can be reshaped into distinct geometries, as demonstrated by experimental and theoretical studies of ∼30 examples. A reconfigurable inductive–capacitive radio-frequency circuit consisting of morphable 3D capacitors serves as an application example.

The press and political continuity in China: The case of the World Economic Herald

This paper, utilizing the method of case study, investigates the role of the Shanghai‐based World Economic Herald in China's political democratization in the 1980s, and analyses its relationship with the social changes of that period.

A prominent theme running through this study is that political democratization must be coupled with economic growth in order for the role of the press to change in China.

Results of the study suggest that the World Economic Herald, throughout its ten‐year existence, became more and more politically oriented and outspoken in its coverage of key political issues. The findings also reveal that in early 1989, the Herald waged an unprecedented struggle against the Party's tight control of the news media and for political democratization including press freedom. However, its role in promoting political change was restricted by the nature of China's reform movement, which was characterized by a separation of political reform from economic reform. The development and demise of the Herald provided a window through which it could be clearly seen how the press affected and was affected by the social changes in China in the historical period of the 1980s.

短距离助跑跳远的生物力学分析

为了探讨短距离助跑跳远这一练习方法的运动生物力学意义，本文对跳远运动员的短距离助跑和全程助跑跳远进行高速摄影和三维测力的同步测试．并通过对其分析和研究，结果表明：１）短距离助跑与全程助跑的水平速度、跳跃距离之差约为１０％；２）起跳时间和力作用于垂直方向的时间比全程助跑长；３）腾起角度大于全程助跑；４）身体重心腾起高度和滞空时间与全程助跑相同。
