产生于晚清、发展于五四时期的女校,在女性解放的过程中,扮演了知识启蒙和精神启蒙的重要角色。近代特殊的国情、西方教会女校的催化作用,以及“五四”的启蒙背景,使得女校突破传统社会的桎梏而得到迅速发展。与家庭及社会所带来的影响不同,女校通过课程教学、文化活动等对女性群体进行集中、科学、系统、深刻的文化濡染。其中,文学作为一种独特的形式,既是启蒙和教育的载体,又成为女学生表达自我思想的输出端口。在女校这个独特的空间场域中,诞生了近现代中国最早的一批女作家,她们一步步浮出历史地表,从边缘处走向历史舞台的中央,从而也改写了文学史和社会史的叙事样貌。尽管女校在很多方面难免存在各种局限,但这不妨碍它成为推动女性解放、激发女性创作的有力支撑。

基于汶川地震震害资料,通过回归分析得到了山区隧道结构整体与各部分的地震易损性模型。选择峰值地面加速度(peak ground acceleration,PGA)作为地震动参数,以对数正态分布函数作为易损性模型,利用极大似然估计得到隧道结构整体及各部分(洞口浅埋段、洞口过渡段、普通段、断层破碎段)的地震易损性曲线,对比分析了隧道整体及各部分的地震易损性特点并进行了探讨。结果表明:轻微破坏条件下,洞口浅埋段的地震易损性要高于其他部分。随着破坏程度的增加,断层破碎带段的地震易损性逐渐高于隧道其他部分。根据隧道结构特定破坏等级的损失比,建立了隧道的平均损失率模型。依据文中建立的隧道易损性模型及平均损失率模型可以在将来发生类似地震时快速地进行地震损失评估。

为研究饱和岩石循环冻融条件下的蠕变力学特性,开展了不同饱和冻融次数三轴蠕变力学试验。根据试样变形特征建立了弹黏塑性蠕变模型,计算了蠕变模型相关参数,研究了饱和循环冻融相关参数变化特征。分析了随冻融次数增加裂隙扩展发育规律,提出了循环冻融蠕变损伤模型,基于试验数据对损伤模型进行了验证。研究表明:饱和循环冻融蠕变过程分为过渡蠕变阶段,稳定蠕变阶段和加速蠕变阶段3个阶段,冻融次数增加蠕变各个阶段均呈缩短趋势。建立弹黏塑性蠕变模型基础上,总结相关蠕变参数随加载应力增加均呈现增大趋势,随冻融次数增加,相同应力条件下蠕变参数逐渐减小。冻融过程中裂隙发育主要分为两种:沿原有裂隙扩展和独立发育的裂隙。原有裂隙扩展速度大于独立发育裂隙产生速度。试样循环冻融过程中裂隙发育速度逐渐增大。考虑冻融次数对蠕变参数的影响,同时引入损伤系数对其影响结果修正,建立蠕变损伤模型解释了循环冻融蠕变损伤过程,模型理论曲线与试验数据对比显示具有较好的相关性,验证了蠕变损伤模型的正确性。

在过渡区内,关于纳米颗粒曳力计算及输运特性的研究较为困难,通常会采用一些近似方法,将自由分子区或者连续介质区的理论计算式进行修正,以适用于过渡区,但是其准确性值得商榷.本文基于分子动力学模拟方法,研究了过渡区内纳米颗粒的曳力特性,并与相关理论进行对比.结果表明,气-固分子间相互作用对纳米颗粒的曳力具有显著影响.当气固结合强度较弱时,理论计算结果与分子动力学模拟值吻合较好;当气固结合强度较强时,分子动力学模拟结果明显大于理论值,这是由于气体分子在纳米颗粒表面的吸附所导致.基于气体分子在颗粒表面的吸附特性,提出引入有效颗粒半径修正,其过渡区内曳力的理论计算结果与分子动力学模拟结果吻合较好.
