宇文所安:汉学语境下的跨文化中国文学阐释

宇文所安对中国文学的研究不是"新批评"的"细读",而是一种跨文化阐释。这种阐释不采用某一种特定的西方理论和方法,而是以自己的文化视角和思维习惯为基础,来对中国文学作品进行深入细致的解读。它是一种生命体验和理性思维并重的跨文化阐释模式。生命体验和理性思维的并重一方面使得理性分析有了更多的感性内容和具体针对性,另一方面也使得感性体悟具备了充分展开的空间。宇文所安的跨文化阐释模式是与美国汉学发展的新方向相一致的。它可以突破"区域研究"的限定,使汉学进入比较文学的研究领域;它能够使中国文学产生超越民族、国家界限的普遍价值,并有可能被更广泛的西方读者所理解、所接受。

Isocyanic acid and ammonia in vehicle emissions

Vehicles are considered to be an important source of ammonia (NH₃) and isocyanic acid (HNCO). HNCO and NH₃ have been shown to be toxic compounds. Moreover, NH₃ is also a precursor in the formation of atmospheric secondary aerosols. For that reason, real-time vehicular emissions from a series of Euro 5 and Euro 6 light-duty vehicles, including spark ignition (gasoline and flex-fuel), compression ignition (diesel) and a plug-in electric hybrid, were investigated at 23 and −7 °C over the new World harmonized Light-duty vehicle Test Cycle (WLTC) in the Vehicle Emission Laboratory at the European Commission Joint Research Centre Ispra, Italy. The median HNCO emissions obtained for the studied fleet over the WLTC were 1.4 mg km⁻¹ at 23 °C and 6 mg km⁻¹ at −7 °C. The fleet median NH₃ emission factors were 10 mg km⁻¹ and 21 mg km⁻¹ at 23 and −7 °C, respectively. The obtained results show that even though three-way catalyst (TWC), selective catalytic reduction (SCR), and NOx storage catalyst (NSC) are effective systems to reduce NOx vehicular emissions, they also lead to considerable emissions of the byproducts NH₃ and/or HNCO. It is also shown that diesel light-duty vehicles equipped with SCR can present NH₃ emission factors as high as gasoline light-duty vehicles at both, 23 and −7 °C over the WLTC. Therefore, with the introduction in the market of this DeNOx technology, vehicular NH₃ emissions will increase further.
