GRENOUILLE飞秒脉冲测量系统中,时间延迟量是一个关键参数,直接决定了飞秒脉宽测量范围。本文量化分析了时间延迟量与菲涅尔双棱镜底角、待测光斑直径等参数之间的关系,研究结果表明,菲涅尔双棱镜底角越大,待测光斑半径越大,双棱镜-SHG... GRENOUILLE飞秒脉冲测量系统中,时间延迟量是一个关键参数,直接决定了飞秒脉宽测量范围。本文量化分析了时间延迟量与菲涅尔双棱镜底角、待测光斑直径等参数之间的关系,研究结果表明,菲涅尔双棱镜底角越大,待测光斑半径越大,双棱镜-SHG晶体间距越大,产生的最大时间延迟量越大,可测得的飞秒脉冲越宽。确定了光路系统中器件参数,通过实验进行了验证,测量结果的误差优于5%,为GRENOUILLE测量系统优化设计提供了参考和依据。 展开更多

Süskind’s “Perfume” constructs the story frame of the text through three sets of contradictory narratives, exploring the process of Grenouille, who is regarded as an alien by others, trying to find and construct true meaning of being a human being from three aspects: human smell, emotion, and discourse. This process constantly encounters deconstruction from its own smelllessness, senselessness and aphasia, thereby implying the lack of human subjectivity and value through Grenouille’s failure to find identity. It also uses the image of perfume to express the author’s deep concerns about the loss of subjectivity, the disillusionment of classical morality, and the violence of industrial civilization in France and even Europe in the eighteenth century. 展开更多
