Bosch and Volkswagen having built vehicles in the 1970s. More recently, the advent of the Electric and Hybrid Vehicle Research, Development and Demonstration Programme in the United States of America initiated the design and construction of a Near Term Hybrid Vehicle (NTHV) with the principal aim of substituting petroleum fuel by wall plug electricity. [6] As part of the NTHV programme, a large number of conceptual studies were conducted but on vehicles aimed at the American passenger car market. In this paper optimization studies were conducted, but now on a vehicle suitable for the European medium-sized passenger car market. Such optimization studies are important as, with two sources of traction power available, the way in which they are controlled, and their relative sizing, is fundamental to the way the vehicle performs.[7] Before examining in detail the optimum control strategy for the drive train, Section 2 defines the hybrid arrangement under study. A description of the optimization process using an appro
分析:第1—2句为总体结论:学校的科技活动是科技教育中的一个重要组成部分。教师认为,学生的科技活动有助于实现科技教育目标。第3~4句为两条具体结论:第一条结论是:课堂上的模拟操作活动经验与实现科技教育的目标有密切关系。第二条结论是:参加科技博览会、父母或其他成人的支持可以提高学生科技活动的效果。第5句展望未来趋势。从上述例子可以看出,通过一项研究工作,可能会得出几条结论,这些结论的主次轻重可以从字里行间表现出来。如例4中的第3句话通过使用…has the strongest relationship…点出了最主要的结论,而在第4句话中运用…also…这个词,来表示递进关系,说明这句话陈述的内容是研究结论之二。有时为了清楚醒目,可以将结论列成几条,例5和例6都是如此。
