Writing is one of the most remarkable skills of mankind. Human culture can be continued and preserved with writing.In the early 20th century, the fountain pen began to replace the brush which had been used by Chinese for more than one millennium. In 1928, the first home-made pen was produced in Shanghai. After new China was founded in 1949, the fountain pen became the most popular writing tool, thanks to its portability and convenience in writing and storage. A 相似文献

The need of inspecting a masterpiece of fine art without affecting it led to develop non destructive methods of investigation. In the field of art conservation, several diagnostic techniques are being widely used to inspect works of art, giving different but complementary results. The present work deals with two of these methods, reflectography and thermography, both techniques examining objects in the infrared spectrum but in different wavelength bands. Their integrated data potentially provide a powerful tool for mapping hidden features and alterations of artworks. This was confirmed during the inspections of a 13th century panel painting under restoration at the Opificio delle Pietre Dure laboratories (Florence, Italy). A graphical user interface was also designed to aid operators in the field of conservation dealing with the results of the two IR methods. Many options such as image adjustment, comparison, overlaying and transparency variation, in addition to thermographic elaborations, have been made available to users. Imaging data integration provides a multi-layered and multi-spectral representation of the painting that yields a comprehensive diagnosis confirms the anomalies individuation and reduces the ambiguities of information coming from a single diagnostic method. 相似文献

Abstract The effect of practice on individual differences and intra-individual variability in reaction and movement times were studied for simple and complex, discrete, motor tasks. Changes with practice for intertrial correlations of adjacent trials and the effects of an increasing number of interpolated trials on intertrial correlations were also observed. For both tasks and for both reaction and movement times, the intra-individual variability decreased with practice. The true score variability for reaction time on both tasks and for movement time on the simple task shows little change with practice. On the complex task, true score variability for movement time decreases with practice. For movement time, adjacent trial correlations increase during the early practice trials then remain stable. For reaction time adjacent trial correlations increase throughout practice. Remoteness effects on intertrial correlations were found for both movement and reaction times for both tasks. 相似文献

Our study explored the contribution of gender role stress (GRS) and sociocultural appearance demands to symptoms of muscle dysmorphia (MD) in a college sample of 219 women and 154 men. For women, five GRS subscales, sociocultural appearance demands, age, and frequency of aerobic exercise predicted MD symptoms (model R2 = .33; F(8,210) = 12.81, p < . 001); for men, only one GRS subscale, age, and sociocultural appearance demands predicted MD symptoms (model R2 = .40; F(3,150) = 9.52, p < .001). Post hoc analyses revealed that a small number of items explained a substantial portion of the variation, suggesting that MD may be more related to specific perceptions of pressure to attain an attractive body than to global gender role stress. 相似文献

对全国健美操联赛青少年测试赛中形态测试结果及测试出现的问题进行分析,并对运动员各身体形态指标做了描述统计和分析。结果显示:从测试赛对形态指标的评分来看,竞技健美操运动员的身材比例要求特点是四肢较长、肩宽、胸厚、腰细、髋窄。运用皮尔逊相关系数的分析计算形态、体能、技能及成套测试得分的相关性,结果显示形态指标与体能、技能、成套测试成绩均无显著相关性,甚至呈一定的负相关性。形态评分标准不符合身体形态促进各项身体素质能力的规律,测试结果不能准确反映运动员竞技能力高低,评分标准不太合理。 相似文献
