摘要：最近在北京观看了原创音乐剧《五姑娘》的演出。据悉,这是该剧入选“国家舞台艺术精品工程”2004—2005年度初选剧目后,经再度打磨修改后第一次亮相北京。作为一名从事音乐剧表演教学的青年教师,想从音乐剧表演艺术的角度谈谈自己的观后感。

摘要：歌剧《苍原》是新时期以来我国正歌剧创演的经典之作。作为此剧创演的幕后英雄和舞台呈现的主帅,曹其敬导演在凸显《苍原》悲壮沉雄的史诗性品格、在二度创作和舞台呈现中创造性地整合歌剧各个构成元素以精心营造歌剧综合美,通过演员的歌唱和表演塑造鲜明歌剧形象方面表现出高超的导演艺术,做出了独特的不可取代的贡献。

摘要：本届大赛最大亮点是参赛选手整体演唱水平可圈可点,高质量歌唱人才的成批涌现可喜可贺,全面展示了我国民族声乐教学近年来的丰硕成果和长足进步;同时,用歌剧表演艺术的视野观察,也在演唱曲目创作、传统音乐修养和综合技能训练等方面对今后民族声乐教学提出了若干亟待解决的新课题。

摘要：初看四川人艺出品的音乐剧《未来组合》（李亭编剧。李海鹰作曲，熊源伟导演）是在我大学即将毕业的1999年；2002年，又在哈尔滨全国歌剧音乐剧观摩演出中第二次欣赏该剧。两次观剧都对剧中洋溢着的人性关爱、成长烦恼及其充满青春时尚气息的舞台演绎印象良好，至今还能依稀记得其中的主要人物和主题歌《星星》。

摘要：Rare-earth orthoferrite SmFeO3 is an outstanding single-phase multiferroic material,holding great potential in novel low-power electronic ***,simultaneous magnetic and ferroelectric orders as well as magnetoelectric(ME)coupling effect at room temperature(RT)in this system have not been demonstrated *** this study,epitaxial SmFeO3 films were successfully prepared onto tensile-strain Nb-SrTiO3(Nb-STO)substrates by a pulsed laser deposition(PLD)*** results show that the films exhibit obvious ferromagnetic and ferroelectric orders at ***,the magnetic anisotropy gradually changes from out-of-plane(OP)to in-plane(IP)direction with increasing film thickness,which is attributed to the variations of O 2p-Fe 3d hybridization intensity and Fe 3d-orbit occupancy caused by the strain-relaxed ***,electrically driven reversible magnetic switching further proves that the SmFeO3 films exhibit the RT ME coupling effect,suggesting promising applications in new-generation electric-write magnetic-read data storage devices.

摘要：板材液压成形是金属板料塑性成形的一种新工艺,非常适合于汽车覆盖件、摩托车油箱等复杂零件的生产。但是板材液压成形工艺与模具的设计目前尚无完善的理论,文章基于板材液压成形的力学分析,设计了一套摩托车油箱的液压成形模具。

摘要：通过对我国西北、东北、上海三个地区国有文艺院团及其歌剧音乐剧生存发展现状、存在的突出问题的了解和判断,本文为处于文化体制改革转型中的歌剧音乐剧创作发展提出了一些建议,以期为我国歌剧音乐剧艺术和音乐剧产业的繁荣发展提供基本保障。

摘要：Controlling the polar order in ferroelectric materials may enrich the diversity of their property and functionality,offering new opportunities for the design of novel electronic and optoelectronic *** this paper,we report a planar multi-state memory device built upon a twodimensional(2D)van der Waals layered ferroelectric material,2Hα-In_(2)Se_(3).Three(high,median and low)resistance states are demonstrated to be interconvertible in this device with a fast switching speed,excellent endurance and retention performances via the modulation of the polar order of the ferroelectricα-In_(2)Se_(3) layers under an in-plane electric ***,reversible switching between the median-resistance state and the low-resistance state can be achieved by an ultralow electric field of 1-2 orders of magnitude smaller than the reported values in other 2D ferroelectric materialbased memory ***,the three different polar order states are discovered to exhibit distinctive *** results demonstrate great potentials ofα-In_(2)Se_(3)in nonvolatile high-density memory and advanced optoelectronic device applications.

摘要：泡菜在发酵过程中易受微生物污染,柠檬精油、香茅精油和肉豆蔻精油的复配精油有良好的抑菌效果,但精油的配比对其有很大的影响。因此,该研究以正交试验设计考察不同配比的复配精油对泡菜发酵过程中品质的影响,采用CRITIC客观赋权法确定各评价指标的权重系数,结合熵权-TOPSIS综合评价,筛选出最适宜在泡菜中使用的复配精油组合。研究结果表明,复配精油的最佳配比为柠檬精油0.05 g/kg、香茅精油0.15 g/kg、肉豆蔻精油0.15 g/kg。该研究可为泡菜的绿色加工提供参考。
