大足石刻艺术博物馆里,那雕刻精美的石刻,虽经千年的岁月侵蚀,略显斑驳,然而岁月却带不走它们的璀璨光辉。作为晚期石窟艺术代表作的大足石刻在吸收、融化前期石窟艺术精华的基础上,于题材选择、艺术形式、造型技巧、审美情趣诸方面都较之前代有所突破,以鲜明的民族化、生活化特色,成为具有中国风格的石窟艺术的典范,与敦煌、云冈、龙门等石窟一起构成了一部完整的中国石窟艺术史,更被列入了世界文化遗产名录。 相似文献

Modern military aircraft jet engines are designed with variable-geometry nozzles to provide optimal thrust in different operating conditions, depending on the flight envelope. How- ever, acoustic measurements for such nozzles are scarce, due to the cost involved in making full- scale measurements and the lack of details about the exact geometries of these nozzles. Thus the present effort at Pennsylvania State University (PSU) in partnership with GE Aviation and the NASA Glenn Research Center is aiming to study and characterize the acoustic field produced by supersonic jets issuing from converging-diverging military style nozzles, and to identify and test promising noise reduction techniques. An equally important objective is to develop methodology for using data obtained from small- and moderate-scale experiments to reliably predict the full-scale engine noise. The experimental results presented show reasonable agreement between small-scale and medium-scale jets, as well as between heated jets and heat-simulated ones. 相似文献

<正>法国玛歌酒庄Chateau Margaux玛歌酒庄(Chateat Margaux),法国波尔多1855列级名庄之一,与拉菲酒庄、拉图酒庄和奥比昂酒庄齐名,美国前总统托马斯·杰弗逊曾将它评为波尔多五大名庄之首。玛歌酒庄除了顶级佳酿之外,还拥有一座最气派的城堡,1946年被列入历史遗产,也是"五大名庄"中,唯一被法国列为国家级博物馆的城堡。身为一级酒庄,玛歌几乎成了玛歌村的焦点,特别是城堡的建筑本身:19世纪初新古典主义风格的建筑,四根高耸的爱欧尼亚式列柱、简洁厚重的柱顶盘与三角楣、24阶的石梯与左右对称的两座人面狮身像,无不彰显酒庄的庄严,高贵。 相似文献

"上海上英雄,伟大民族,不朽的国家葡萄牙……"这是葡萄牙国歌《葡萄牙之歌》开头的歌词。这个世界上最古老的航海大国,守望着大西洋,以海兴市,曾经辉煌一时,并以船坚炮利殖民征服了比本土大100倍的疆土。而今,这里是一片欣 相似文献
