氢化物发生-多接收杯电感耦合等离子体质谱同位素稀释法测定硒同位素

使用改进的巯基棉分离流程和^74硒-^77硒双稀释剂，在氢化物（HG）-多接收器电感耦合等离子体质谱仪（MC—ICP—MS）实现了高精度硒同位素组成的测定。巯基棉用于分离样品基质中的硒，随后使用HNO3＋H2O2消除干扰的有机质，^74硒-^77硒双稀释剂校正样品分离和质谱测定过程中的硒同位素质量分馏。硒标准溶液NIST SRM5149和MH495几个月的测定表明，该方法的外精度为0．1‰（2σ），样品的外精度为0．15‰～0．2‰（2σ）。以TCF分离硒的平均回收率85％计算，最小硒需要量为20ng。实验结果以相对于NIST SRM3149的δ^82／76Se表达，δ^82/76MH98/SRM3149=-3．44±0．1‰（2σ），优于已发表的数据δ^82/79MH495/SRM3149=-3．04±0．5‰。测定样品的δ82/76 SRM3149为-13．53‰～11．37‰，为硒同位素在环境、农业、生命和地球科学中的拓展应用与发展奠定了基础.

Nouvelles approches de la ville dans la littérature française contemporaine : Thomas Clerc et Philippe Vasset

On the basis of two indecidable texts (Thomas Clerc, “Paris, musée du XXIe siècle. Le dixième arrondissement”, Gallimard 2007 and Philippe Vasset, “Un livre blanc”, Fayard 2007), we will reflect on new approaches to the city in contemporary French litterature. Clerc and Vasset, in their respective texts, suggest considering litterature as a series of practices connected with the exploration of the city (Clerc) and of the urban area (Vasset) according to the idea of an arbitrary itinerary. The image of the city whose space, subject to a permanent process of museifi cation, is constantly considered to be a work of art (Clerc) contrasts with a project of viewing the deserted areas of the city and of its surroundings as an infinite collection of “artistic installations” created in daily life (Vasset). Clerc’s and Vasset’s artistic mentality leads them to the fascination with “works of involuntary art”, both concrete signs and tangible proof of the transitional period which they try to describe systematically, following, at the same time, the principles of an axonometric city map.
