Jianzhu Gangjiegou Jinzhan, 2023 双钢板-混凝土组合剪力墙作为建筑物中的抗侧力构件，具有承载力高，耗能能力强和延性好等优点。在高层和超高层建筑结构中，双钢板-混凝土组合剪力墙需要承担一定的竖向荷载，钢板在正常使用阶段要求不发生弹性屈曲。钢板初始几何缺陷是影响双钢板-混凝土组合剪力墙轴压荷载下钢板屈曲应力的重要指标，而在以往的研究中，钢板屈曲应力的计算方法并未予以考虑。本文基于前期的双钢板-混凝土组合剪力墙轴压试验研究，采用分析软件ABAQUS建立了双钢板-混凝土组合剪力墙轴压试件有限元模型，模型中引入了钢板的初始几何缺陷，从钢板屈曲应变、

The Decomposition of the Inflationary Effect of Oil Price Shocks [PDF]
, 2013 通货膨胀是关系国计民生的重大问题，一直是公众和理论界关注的焦点。近年来经济高速发展带来物价水平居高不下，物价水平再次成为聚焦点，同时2012年原油对外依存度已经达到56.4%，国内原油缺口还将继续增大，国内油价受国际原油价格变动影响越来越明显；成品油价格不断调整，这些给本来已经广受热议的物价水平无疑是火上浇油，增大了我国的通货膨胀管理工作难度。 在此背景下，本文将石油价格上涨对通货膨胀造成的影响分解，即将通货膨胀响应分为需求响应和供给响应；利用因子增广向量自回归（FAVAR ...

Zhongguo shiyan zhenduanxue, 2012 近年来椎弓根螺钉固定技术得到了广泛的应用和发展。然而在术中置钉过程中难免会出现椎弓根螺钉"抬头、低头"等问题。术者为追求两侧螺钉的平行与对称常常需要更改原来螺钉的轨道。这样的结果往往会影响螺钉的固定的强度,同时也会延长手术的时间。有没有必要一定要追求两侧螺钉平行对称呢?本实验通过比较平行和交叉置钉方法应力差异分析两种方法的优劣。
