《星期天和乔治在公园》的跨/多媒介叙事

在跨媒介、多媒介叙事的研究视角下,文章着重分析音乐剧《星期天和乔治在公园》中绘画、音乐、剧诗等艺术媒介的互动,包括跨媒介转换与多媒介融合。从文图关系的角度,修拉的点彩画技法和画作《大碗岛上的星期天下午》为该音乐剧创作提供了舞台布景、戏剧张力与艺术主题,从而使视觉元素与戏剧叙事相互融合;从音乐与戏剧结构的角度,词曲作者史蒂芬·桑德海姆通过音乐联系起两幕的平行叙事结构并运用三种音乐动机丰富了音乐与戏剧元素的表达;从多媒介艺术的角度,桑德海姆进而通过跨媒介转换与“整合”艺术思想使绘画、音乐和剧诗等多种艺术媒介实现了融合,从而创造出音乐剧叙事中通感式的美学体验。From the perspective of cross-media and multi-media narrative research, this paper focuses on the interaction of artistic media such as painting, music, and lyrics in the musical Sunday in the Park with George, including cross-media transformation and multi-media integration. From the perspective of the text-image relation, Seurat’s pointillist technique and the painting A Sunday Afternoon on the Island of La Grande Jatte provided the stage setting, dramatic tension, and artistic theme for the creation of this musical, thus fusing visual elements with dramatic narrative. From the perspective of music and dramatic structure, the lyricist and composer Stephen Sondheim linked the parallel narrative structure of the two acts through music and used three musical motifs to enrich the expression of musical and dramatic elements. From the perspective of multi-media art, Sondheim further achieved the fusion of multiple artistic media such as painting, music, and lyric through cross-media transformation and the artistic idea of “integration,” thus creating a synesthetic experience in musical narrative.

基于系统多工况运行参数的设备性能指标评估方法

用实际运行参数评估设备性能指标时,由于只能观测不同工况下阀门开度和阀前后压力等少量的运行参数,所以很难用现有的传统模型计算设备的性能指标。通过设备在不同工况下的性能指标,得到较丰富的可观测参数,再利用可观测参数估算设备性能指标的反问题研究方法,构建少量观测参数与设备性能指标之间的关系,建立分析设备内部性能的模型。最后通过仿真计算验证其可行性,为热力系统的使用与维修决策提供技术支撑。
