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
