青花瓷是一种釉下彩绘瓷。它是在一定条件下,整合历代烧瓷技艺的产物,是中国陶瓷进入彩瓷阶段的重要标志。其工序是先在胎上用青科画好花纹,再罩一层透明的白釉,经高温一次烧成。色料充分渗透坯胎和釉之间,釉下的青花纹饰永不褪色。 相似文献

自明代以来,福建德化窑逐渐步入了一个异彩纷呈口的时代,其产品除以白釉(尤其是“象牙白”)的独特风格驰名于世外,同时也开始在白瓷上进行着色装饰,出现同样倍受世人喜爱的青花瓷、五彩瓷、粉彩瓷等各种彩瓷,并且沿袭至今。 相似文献

红绿彩是磁州窑系继剔花、白底黑花等装饰技法之后,创新出的另一种瓷器装饰艺术。它是在高温白釉或白釉黑彩瓷烧成之后,在白釉之上以红、绿、黄等彩料勾画或添涂出纹饰,再次入窑以低温烧制而成,以往曾称作“宋加彩”。遗憾的是,经过漫长的历史岁月,作为磁州窑系重要产品的完整的八义窑红绿彩瓷器如今只在美国、日本和国内的几处重要博物馆有收藏。 相似文献

20世纪90年代中期,南京黄浦路2号“黄埔广场”建筑工地（明故宫遗址内）发现一日深达11米的残井,出土一件轰动文博界的瓷器——明洪武官窑白釉褐彩“赏赐”款梅瓶。这是继1964年在疏浚南京明故宫遗址御城河时发现青花瓷、釉上红彩五龙盘、内外双色釉暗龙纹碗等洪武官窑瓷器之后的又一次重大发现。 相似文献

宋代以来景德镇的瓷器以青白釉刻、印、捏塑、点褐彩等装饰为主。元代中后期景德镇陶工们真正掌握了用钴料在瓷胎上进行彩绘,成功地创烧了青花瓷,从此翻开了彩绘装饰瓷器的辉煌一页。元代延祐时期的青花瓷烧成后青花呈蓝褐色。九江博物馆藏缠枝牡丹纹塔式盖 相似文献

福建德化白瓷烧成后玻璃相较多,胎质致密,透光度十分良好,是多数同时代窑口的产品所不能比拟的。因此,在16世纪初被誉为“中国白”的德化白瓷曾大量输出欧洲,受到举世赞誉。明末德化窑已烧出青花瓷,上海博物馆所藏德化白釉铺首瓶带有“明朝天启四年岁次甲子 相似文献

AbstractThe aim of this study was to examine the effects of changes in maximal aerobic (MAS) and sprinting (MSS) speeds and the anaerobic reserve (ASR) on repeated-sprint performance. Two hundred and seventy highly-trained soccer players (14.5 ± 1.6 year) completed three times per season (over 5 years) a maximal incremental running test to approach MAS, a 40-m sprint with 10-m splits to assess MSS and a repeated-sprint test (10 × 30-m sprints), where best (RSb) and mean (RSm) sprint times, and percentage of speed decrement (%Dec) were calculated. ASR was calculated as MSS-MAS. While ?RSb were related to ?MSS and ?body mass (r2 = 0.42, 90%CL[0.34;0.49] for the overall multiple regression, n = 334), ?RSm was also correlated with ?MAS and ?sum of 7 skinfolds (r2 = 0.43 [0.35;0.50], n = 334). There was a small and positive association between ?%Dec and ?MAS (r2 = 0.02 [?0.07;0.11], n = 334). Substantial ?MSS and ?MAS had a predictive value of 70 and 55% for ?RSm, respectively. Finally, ?ASR per se was not predictive of ?RSm (Cohen’s = +0.8 to ?0.3 with increased ASR), but the greater magnitude of ?RSm improvement was observed when MSS, MAS and ASR increased together (0.8 vs. +0.4 with ASR increased vs. not, additionally to MSS and MAS). Low-cost field tests aimed at assessing maximal sprinting and aerobic speeds can be used to monitor ?RS performance. 相似文献

论新生活运动正当娱乐中的体育 总被引：1，自引：0，他引：1
新生活运动历时15年,涉及到了国民生活的方方面面。娱乐作为生活的重要组成部分,也受到新生活运动的影响。为了纠正社会上根深蒂固的“烟”、“赌”和“娼”等不良风气,新生活运动组织十分重视对正当娱乐的提倡,对体育尤为重视。蒋介石本人在新生活运动周年纪念大会上专门提到过体育问题。体育活动曾被作为新生活运动的年度中心工作或者工作要点来开展。虽然最后对体育的提倡没有达到十分理想的效果,但确实引导了国民的健康观念。新生活运动组织还培养了数量不多的体育人员,为近代体育的发展注入了动力。 相似文献

A physiotherapist is part of the multidisciplinary team in most intensive care units in Australia. Physiotherapists are primary contact practitioners and use a comprehensive multisystem assessment that includes the respiratory, cardiovascular, neurological, and musculoskeletal systems to formulate individualized treatment plans. The traditional focus of treatment has been the respiratory management of both intubated and spontaneously breathing patients. However, the emerging evidence of the longstanding physical impairment suffered by survivors of intensive care has resulted in physiotherapists re-evaluating treatment priorities to include exercise rehabilitation as a part of standard clinical practice. The goals of respiratory physiotherapy management are to promote secretion clearance, maintain or recruit lung volume, optimize oxygenation, and prevent respiratory complications in both the intubated and spontaneously breathing patient. In the intubated patient, physiotherapists commonly employ manual and ventilator hyperinflation and positioning as treatment techniques whilst in the spontaneously breathing patients there is an emphasis on mobilization. Physiotherapists predominantly use functional activities for the rehabilitation of the critically ill patient in intensive care. While variability exists between states and centers, Australian physiotherapists actively treat critically ill patients targeting interventions based upon research evidence and individualized assessment. A trend toward more emphasis on exercise rehabilitation over respiratory management is evident.Key Words: physiotherapy, intensive care 相似文献

AbstractLateral movements like cutting are essential in many team sport disciplines. The aim of the present study was to analyse adaptations in motor control in response to task unpredictability during lateral movement execution. Twelve subjects performed lateral jumps with different landing modalities (stable, sliding or counteracting) that were either known (predictable setting) or unknown (unpredictable setting) prior to movement execution. Results revealed that regardless of the landing modality, hip joint abduction was significantly greater in the unpredictable compared to predictable setting. Furthermore, during the sliding landing modality, hip flexion decreased from 211 ± 7° to 207 ± 7° and knee flexion decreased from 26 ± 4° to 24 ± 4° at the instant of ground contact in the unpredictable compared to predictable condition. During the stable landing modality, the knee joint abduction increased from ?0.3 ± 6° to ?3 ± 6° after initial ground contact in the unpredictable compared to predictable setting. The present results support our hypothesis that pre-programmed motor activity depends on the predictability of the landing modality during lateral movements. According to its adaptation in the frontal plane and in some extent in the sagittal plane, the hip joint seems to play the major role in the modulation of the pre-programmed activity for successful lateral jump execution in an unpredictable setting. However, these kinematic adaptations are concerning since these changes were associated with higher knee abduction during the stable landing modality and therefore with possible higher risk of injury. 相似文献
