摘要：David’s Story by Zoë Wicomb addresses the complexities of representing female suffering and the limitations of traditional historical narratives in capturing the experiences of marginalized *** challenges the grand narratives of national history by emphasizing the indispensable role of women’s *** characters like Dulcie and Rachael,Wicomb portrays the female body as a site of resistance and resilience,highlighting the need for more nuanced and inclusive ways of documenting *** the inexpressibility of trauma and the limitations of language and representation,the novel self-reflexively acknowledges its own aporia of completing the narrative,embodying the ongoing struggle to capture the full breadth of human experience.

摘要：An electronic speckle shearing phase-shifting pattern interferometer (ESSPPI) based on Michelson interferometer was based in this paper. A rotatable mirror driven by a step motor in one of its reflective arm is used to generate an adjustable shearing and the mirror driven by piezoelectric transducer (PZT) in the other reflective arm was used to realize phase- shifting. In the experiments, the deformation of an aluminum plate with the same extern-force on different positions and different forces on the same position is measured. Meanwhile, the phase distribution and phase-unwrap image of the aluminum plate with the extern-force on its center position is obtained by the four-step phase-shifting method.

摘要：In the Heart of the Country,the second novel by ***,has been traditionally read as a disembodied writing that focuses on the problem of writing per se instead of the *** paper contends that the work is actually a body narrative that explores the visceral pain suffered by Magda whose infertile body impedes her being a qualified *** the heroine in a postcolonial novel,Magda is not just a body that is restricted and constructed by the politics of the body,but also a thinking and writing body that consciously questions and resists the gendered bodily norms under whose yardstick her subjecthood is *** in the metafictional manner,Magda’s narrative of the body is not just a record of her corporeal experience,but also a self-conscious negotiation with,and challenge of,the bodily norms under whose yardstick her body has been debased or,in terms of Judith Butler,*** her female bodily experience as the starting point,Magda writes a feminine text that values passion,fluidity and non-linearity to disrupt the patriarchal discourse underpinned with logical *** feminine body narrative endeavors to achieve a new way of communication through which a reciprocal cross race/gender relationship might be established.

摘要：针对空间索面悬索桥的非线性振动问题,采用一种基于连续介质理论的广义模型开展了非线性主共振参数分析.该模型同时考虑了悬索桥的桥面竖向运动和缆索竖向-水平运动的几何非线性特点.基于该模型和时间多尺度法,推导了求解空间索面悬索桥的竖弯模态主共振响应的调制方程.研究表明,调制方程中的非线性系数会显著影响系统主共振的最大响应幅值,并影响竖弯振动模态的硬化或软化特性.此外,主缆与吊杆的倾角、主缆垂跨比、主梁与主缆的抗拉刚度比等系统参数对非线性系数同样存在显著影响,特别是当系统参数位于奇异点附近时,系统的动力特性会随梁体和主缆的对称振动模态对应的非线性系数突变而剧烈变化,在系统设计中应避免这种情况.该研究能够为该类桥梁的结构设计提供参考.
