中国钢琴音乐创作概述

中国钢琴音乐创作始于20世纪初,20世纪10～20年代为初创时期,其创作技法简单,结构短小,基本表现为歌曲加伴奏的形式;20世纪30～40年代为发展成熟时期,创作技法逐步提高,旋律清晰优雅,织体结构简洁,民族特点突出;20世纪50年代为繁荣时期,专业创作群体形成,作品数量质量大大提高,民族风格鲜明;20世纪60～70年代,以民歌和民族器乐为原形的钢琴改编曲大量出现,改编曲风格基本形成;20世纪80年代以后,钢琴音乐创作出现多元化的特点,探索新技法、体现新风格成为这一时期创作的突出特征。     

核心稳定性研究历史与现状

核心稳定性是一个广泛应用于包括健康和医学领域在内的多领域的常见术语,科学文献中有关核心稳定性定义的表述各不相同。通过对“核心”的位置、核心稳定性中的稳定性的定义、核心稳定性的构成的分析,确定人体“核心”的位置,探讨“核心稳定性”中的“稳定性”的内涵,分析核心稳定性的生物力学原理。     

男大学生体成分与脑血流速度相关性研究

探讨身体成分与脑血流速度（Cerebral Blood Flow Velocity,CBFV）的关系,以便揭示体脂对CBFV的影响。方法：以10名男大学生为实验对象,应用经颅多普勒技术检测了其安静时的大脑中动脉血流速度和采用In Body身体成份分析仪测试了其身体成分,然后对CBFV和身体进行了相关分析。结果：大脑中动脉收缩期峰速度（Vp）、舒张期末峰速度（Vd）和平均峰速度（Vm）分别与其体脂、体脂百分数和体重指数（BMI）呈显著负相关;而大脑中动脉的搏动指数（PI）分别与体脂百分数和BMI呈显著正相关。结论：体脂对CBFV有显著的负面影响,体脂增多,CBFV降低。     

Medieval and renaissance glass technology in Valdelsa (Florence). Part 1: raw materials, sands and non-vitreous finds

A significant number of archaeological finds of the 13th–16th century from the Tuscan sites of Germagnana and Gambassi in Valdelsa—FI, was studied by different physico-chemical investigations (SEM–EDS, ICP, Mössbauer spectroscopy, XRD, XRF, TG-DTA) in order to contribute to clarify the production methodology and the pre-industrial glass manufacture technology. The studied samples are mainly non-vitreous finds as production waste, refractory materials, crucibles and raw materials; also vitreous finds as frits, skims, glasses (glass masses, glass working waste and finished products) have been taken into consideration. The obtained petrographic and physico-chemical data strongly suggest that both Gambassi and Germagnana glass manufactures were strictly connected with the sources of vitrifiable materials, situated in Tuscan sand quarries. In particular a comparison between sands from the neighbouring quarries and appropriate finds of the two archaeological sites evidences that the employed vitrifiable materials possibly belong to La Casina La Cava resort. The archaeological classification, based on macroscopic observation and stratigraphic position, was compared and verified with the scientific classification of the examined finds of Germagnana and Gambassi sites based on their composition, morphology and physico-chemical properties.

论油画风景写生中的意境要素

优秀风景画的“源头活水”是大自然与艺术家真实情感的体验和流露熏是在写生中通过体验、观察、感悟。境是生活现象的客观反映熏意是艺术家情感、理想的主观体现熏意境是在主客观两方面的有机统一,是生活的真实转化为艺术的真实,是艺术家情感与形式美感的有机结合。一幅风景油画如果没有意境熏就等于没有灵魂。“意境”是风景油画的主题、是灵魂。一切意境的形成都是以情感为基础熏情又是意境核心。     

企业家也是一种生产力

企业家是创新专家。企业家不仅自身就是综合素质较高的劳动,而且企业家还通过“要素组合”创造生产力;通过调整和完善企业生产关系奠定企业生产力发展的制度基础。企业家的形成机制与生产力发展机制的契合,则为社会生产力的发展提供动力。

Moderate Association of Anthropometry,But Not Training Volume,With Race Performance in Male Ultraendurance Cyclists

In 28 male Caucasian nonprofessional ultracyclists, we investigated whether anthropometry or training volume had an influence on race speed in the 600 km at the Swiss Cycling Marathon 2007. Anthropometric parameters (age, body mass, body height, skin-fold thicknesses) were determined before the race to calculate body mass index and percent body fat. In addition, participants, using a training diary, recorded their training volume in hours and kilometers in the 3 months before the race. The influence of anthropometry and training volume on speed in the race as the dependent variable was investigated in a multiple linear regression model. Anthropometry showed a moderate association with speed in the race (r² = .178, p < .05), whereas training volume showed no association (r² = .000, p > .05). We concluded that anthropometry had a greater influence on race performance than training volume in recreational ultraendurance cyclists.
