"国家的艺术形象"与"艺术的国家形象"--兼谈人民大会堂《江山如此多娇》的文化内涵

人民大会堂是我国最高的政治活动中心,又是最高的艺术殿堂,艺术与政治相互关系的理论上的阐释,在这里得当了最有效的实证;人民大会堂里的中国画如果被称谓“艺术的国家形象”,确切地说是最能代表着“国家的艺术形象”;人民大会堂的《江山如此多娇》画作,无论是创作主体,还是作品展示场地及其化内涵,都可以说是政治与艺术结合的结晶。     

Correlation analysis-based image segmentation approach for automatic agriculture vehicle

INTRODUCTION In recent years,harvesting crop by combine has become more and more popular in China.In2003,combines were used to harvest23%of rice and71%of wheat.The work described here is part of a pro-ject aimed at researching automatic combines who follow the cut-uncut edge of the crops automatically to reduce the driver’s fatigue from the intensive work.Much attention has been focused on vision-bas-ed automatic agriculture vehicle.Image segmenta-tion is the key to extracting the guida…     

Remote ischaemic preconditioning shortens QT intervals during exercise in healthy subjects

The protective action of remote ischaemic preconditioning (RIPC) has been demonstrated in the context of surgical interventions in cardiology. Application of RIPC to sports performance has been proposed, but its effect on the electrocardiogram (ECG) during exercise remains unknown. This exploratory study aims to measure the changes in ventricular repolarization observed during exercise following RIPC in healthy subjects. In an experimental randomized crossover study, 17 subjects underwent two bouts of constant load exercise tests at 75% and 115% of gas exchange threshold (GET). Prior to exercise, they were allocated to either control or RIPC intervention with four cycles of 5?min of ischaemia followed by 5?min of reperfusion. ECG was continuously recorded during the protocol. QT and RR intervals were measured every 30?s (on an average tracing of the preceding 10?s). Although the time course of RR intervals did not differ between the two interventions (p?=?.56 at 75% GET and p?=?.74 at 115% GET), a significant shortening of QT intervals (measured from Q onset to T end) was observed during exercise (mean?±?standard deviation of RIPC vs. control: ?32?±?19?ms at 75% GET (p?p?p?p?相似文献   

思妇诗及其月亮意象

月亮意象在古典诗词中极为常见,且尤以思妇诗中出现次数最为频繁.月亮虽然只是自然界中的纯客观的物象,但它却逐渐成为华夏之邦"人化自然"的重要组成部分,也成为诗人某些特定情感的信息载体,并在规定的语境中,展示出了怀人思远的情感寄托流程及其鲜明的"哀而不伤"的审美趋向.论文从思妇诗的缘起及其诗中有关月亮的情境融合,来论述月亮成为思妇诗中一个重要意象的缘由.
