从功能对等角度看汉语兼语句的英译

萍乡高等专科学校学报 2009年第4期26卷 70-72页

作者：黄峰斌重庆师范大学外国语学院重庆400047

英汉句子结构存在着差别,尤其体现在谓语动词上。相对英语而言,汉语兼语句为汉语一大特色。本文从分析汉语兼语句的结构特征入手,通过英汉句子谓语动词对比,以奈达的功能对等理论为指导探讨汉语兼语句的英译方法。

On-road tailpipe ammonia (NH3) emissions contribute to urban secondary organic aerosol formation and have direct or indirect adverse impacts on the environment and human health. To understand the tailpipe NH3 emission characteristics, we performed comprehensive chassis dynamometer measurements of NH3 emission from two China 5 and two China 6 light-duty gasoline vehicles (LDGVs) equipped with three-way catalytic converters (TWCs). The results showed that the distance-based emission factors (EFs) were 12.72 ± 2.68 and 3.18 ± 1.37 mg/km for China 5 and China 6 LDGVs, respectively. Upgrades in emission standards were associated with a reduction in tailpipe NH3 emission. In addition, high NH3 EFs were observed during the engine warm-up period in cold-start cases owing to the intensive emissions of incomplete combustion products and suitable catalytic temperature in the TWCs. Notably, based on the instantaneous NH3 emission rate, distinct NH3–emitting events were detected under high/extra high velocity or rapid acceleration. Furthermore, NH3 emission rates correlated well with engine speed, vehicle specific power, and modified combustion efficiency, which were more easily accessible. These strong correlations were applied to reproduce NH3 emissions from China 5/6 LDGVs. The predicted NH3 EFs under different dynamometer and real-world cycles agreed well with existing measurement and prediction results, revealing that the NH3 EFs of LDGVs in urban routes were within 8.55–11.62 mg/km. The results presented here substantially contribute to improving the NH3 emission inventory for LDGVs and predicting on-road NH3 emissions in China.

针对光伏、燃料电池等新能源发电系统所需的高升压比的应用场景,提出一种交错并联三绕组耦合电感高增益Boost变换器。以交错并联的控制方式减小了耦合电感原边电流纹波,切分了占空比从而减少了各开关管导通时长,交错并联的开关管与输出开关管在电路结构上实现了电压钳位,不会出现电压尖峰。桥式倍压单元缓解了二极管反向恢复问题。交错并联耦合电感双原边的构造提高了变换器的工作可靠性。另外,基于该变换器还拓展出交错并联n+1绕组耦合电感高增益Boost变换器和n耦合电感交错并联n桥式倍压高增益Boost变换器。围绕所提变换器的工作原理及稳态性能进行了深入分析。且在理论分析的基础上通过实验平台制作了一台功率为500 W的样机验证了其准确性。
