延安时期,陕甘宁边区政府通过倡导大生产运动,间接完成了对边区军民的组织动员工作。“劳动”作为关键词频繁出现于延安时期的戏剧作品中,“劳动”与戏剧以连接边区军民民族国家想象的姿态出场。有关劳动叙事戏剧作品的涌现,既是戏剧生产组织对边区中央政策的主动响应,亦是剧作家群体在充分考量边区军民主体情感诉求基础上的有意识书写。延安戏剧作品作为文学作品中最具典型性的“文本”,通过劳动叙事及其文化表征,具象呈现了边区“新人”的形象塑造与“新式家庭”的生成过程,进而有效激发了军民团结抗战的革命热情,促进了新的革命主体的生成。

Acetone is a tracer for monitoring air quality and a potential breath maker for diabetes. It remains a great challenge for current portable sensors to sensitively and selectively detect acetone at low-ppb (part per billion) level. Herein, we present an ordered mesoporous nickel oxide (NiO) with both large mesopores and ultrathin crystalline frameworks for the detection of low-ppb acetone. The ordered mesoporous NiO replicas with predominant large mesopores of 11 nm, high specific surface areas of 121–128 m2/g and ultrathin crystalline frameworks of 5 nm were synthesized by the nanocasting method and the crystalline properties of NiO frameworks were adjusted by changing the annealing temperature from 300℃ to 750℃, which resulted in different contents of oxygen deficient on the surface of ultrathin frameworks. The gas-sensing properties for all the NiO samples were investigated and the ordered large-pore mesoporous NiO (NiO-600) with maximum oxygen deficient obtained at 600℃ exhibited the highest response (R_(gas)/R_(air)−1=2.9) toward acetone (1 ppm, ppm: part per million), which is 3.4 and 30 times larger than those for common mesoporous NiO obtained at 300℃ and bulk NiO. Notably, a low detection limit (2 ppb), good selectivity and cycling stability were also observed in NiO-600.
