土结构性是土结构空间排列几何特征和联结特征所表现出的力学性质,是影响土力学特性的重要内在因素。它与土的密度、粒度、湿度相联系,能够综合反映土的强度、变形等力学特性的变化和发展。从综合反映增湿导致土结构内在主动变化和加载变形导致土结构被动变化两个方面出发,沿用土综合结构势的应力比结构性参数,首先建立压缩、剪切及增湿作用下黄土的结构性演化规律;其次,通过压剪湿作用下黄土的应力-应变特性、屈服破坏特性及其与结构性之间的关系,揭示结构性变化对土力学性质的影响;进而,建立了反映压剪湿作用下黄土结构性发展演化的湿载结构性本构模型。最后通过与试验数据、修正剑桥模型的比较分析,初步验证该模型的准确性。

本文以湿空气透平和压缩空气储能系统中的工质-湿空气为研究对象,运用所提出的一个适合计算高温高压湿空气热力学性质的对应态维里方程,对湿空气的偏差焓和偏差熵进行了计算。在湿度0≤W≤1kg/kg(A),温度小于573．15K,压力小于5 MPa时,与ASHRAE用的多项式维里方程计算得到的偏差焓和偏差熵进行了比较,误差很小。用这个对应态维里方程外推计算了温度和压力分别达到600 K和15 MPa的湿空气焓和熵。计算结果表明对湿空气而言压力和湿度越大,偏差焓和偏差熵越大;温度越高,偏差焓和偏差熵越小。

日据末期中国台湾作家运用殖民者语言,策略性地建构具有民族特色的言说世界,挑战殖民者的文化霸权;挪用写作权力来反思殖民当局近代化论述的破绽、重新体认中华传统文化的价值。中国台湾作家从“被动”生产的小说文本,敷衍殖民当局的文艺统制政策,转为书写回归乡土、民俗传统与歌颂劳动之美。那种认为中国台湾作家已经屈服于殖民当局的研究观点并不正确,应该正视中华优秀传统文化在反殖民文学书写中的作用。

利用台风最佳路径、bimodal IntraSeasonal Oscillation(bimodal ISO)指数和全球逐日向外长波辐射数据,研究了北半球夏季季节内振荡(Boreal Summer IntraSeasonal Oscillation,BSISO)年代际变化造成1996/1997年后西北太平洋群发台风突变减少的可能机制。分析显示,仅有包含3个及以上个数台风成员的“MTC3”群发出现了突变减少,此类台风更倾向在传播速度较慢、低频对流维持时间较长的BSISO活跃位相内出现,对次季节信号强度的要求相对较低。1996/1997年后,BSISO东传范围减小、周期延长、对流活跃位相日数缩短,导致西北太平洋长时间连续维持对流抑制位相,低频对流在145°E以东海域的强度减弱。当偏西海域有先导台风活动时,它向东南侧激发的罗斯贝波频散波列在(5°—20°N,145°—165°E)海域因没有低频对流耦合而快速消散,导致MTC3群发台风年代际突变减少。
