“黄河”舞蹈话语是中华民族共同体的“动觉符号系统”的重要组成部分。乡土与革命是“黄河”舞蹈话语反复书写的两大主题,前者促成了“黄河派”舞蹈艺术创作,后者推动了“黄河主题”舞蹈艺术创作。“黄河”舞蹈话语受到中华民族社会框架、同质性认知及表征符号系统的制约,它基于时空关联、群体关联和可重构性三个维度,立足当下,重塑集体记忆,从政治与文化两个方面助力构建中华民族的国族认同。按照“黄河”舞蹈话语铸牢中华民族共同体意识的实践逻辑来看,它在时代语境中以动觉符号具象化了集体记忆,在艺术创作中以行动实践诠释了社会意义,进而可以为中国故事的表征赋能,为铸牢中华民族共同体意识的进程提质增效。

受台风与季风降水的不同影响,我国东南沿海地区前后汛期极端降水差异显著。为揭示该区域前后汛期极端降水危险性的差异,以福建省为典型区,应用熵权-CRITIC组合权重模型赋权的TOPSIS方法,选取最大1 d降水量、最大连续5d降水量、降水强度、暴雨时间和强降水量等5项代表性指标,分别对25个气象站点1960—2020年的前后汛期极端降水危险性进行评价。结果表明:1)福建省前汛期极端降水危险性指数总体较高,呈现自东部沿海向西北山区递增的趋势;后汛期极端降水危险性总体较低,呈现自东部沿海向西北山区递减的趋势;2)福建省前后汛期极端降水危险性指数差异大,可分为前汛期显著型站点14个、前后汛期相当型站点6个和后汛期显著型站点5个。因此,区分前后汛期并分别进行极端降水危险性评价,能够更合理地揭示区域极端降水危险性及其空间变化的规律,为区域防汛抗涝、水土保持等工作提供科技支撑。

随着人口老龄化加剧,仅仅利用财政资金已不能满足养老服务多样化的需求,为此,亟需将PPP模式引入养老项目。基于PPP养老项目特征,必须对其进行严格审计才能确保养老事业可持续发展。但是,传统PPP养老项目审计存在科学性不足、自我完善体系缺失、监管不够、风险意识薄弱等问题,审计效果有待提升。基于此,设计依托区块链视角、全生命周期、全过程跟踪的大数据审计方案,实现对PPP养老项目深度审计,进而促进PPP养老项目规范运行,最终实现养老产业健康发展。

通过对某660 MW电厂失电事故过程中烟气温度、蒸汽温度及工质流量的变化规律进行分析,得到了炉膛密相区、过渡区及稀相区热负荷随时间的变化规律。在此基础上,以某700MW超超临界循环流化床(circulating fluidized bed,CFB)锅炉为对象,建立了失电事故发生后水冷壁内的流动传热计算模型,开发了以Fortran语言为基础的水冷壁内瞬态特性计算程序。分别对密相区、过渡区及稀相区进行分析,通过计算得到了失电后的水冷壁壁温及出口工质温度等热力参数的变化规律。计算结果表明:失电后水冷壁密相区出口的最高壁温为558.6℃,稀相区出口的最高壁温为579.6℃,不需要配备紧急补水泵来保证失电后水冷壁的安全。研究结果可为电厂处理超超临界CFB锅炉失电事故提供指导。
