为研究表面粗糙度对接触表面力学行为的影响规律,结合表面粗糙度的加工参数和随机抽样方法,对服从正态分布和预设粗糙度的表面轮廓曲线进行了模拟.根据统计得到的模拟轮廓曲线几何形态的共性特征,建立了基于圆锥与平面接触的三维粗糙表面接触力学模型,推导出平面几何压力与粗糙表面微凸体变形间的定量关系.分析结果表明:服从正态分布的轮廓高度曲线中的峰角顶点数目约为样本容量的1/3;圆锥压入平面时平均压力/材料纯剪应力的比值与其半角呈二次方关系;表面粗糙度越大,轮廓曲线的起伏越大,两接触面相互嵌合越容易;表面粗糙度越大,材料屈服强度对接触微凸体变形的影响也越明显.

近年来国内理论界和学术界对农村土地流转(此处指农村土地承包经营权的流转。主要包括转包、出租、互换、转让、股份合作等流转形式)问题进行了大量研究,但对具有典型意义的某一地区或者村落进行全方位调查和透彻剖析的文献还相对较少... 详细信息

近年来国内理论界和学术界对农村土地流转(此处指农村土地承包经营权的流转。主要包括转包、出租、互换、转让、股份合作等流转形式)问题进行了大量研究,但对具有典型意义的某一地区或者村落进行全方位调查和透彻剖析的文献还相对较少。笔者借助西万村的典型案例运用现代经济学的分析思想,并运用调查研究法、博弈分析法,在博弈分析的过程中发现了中介组织的突出作用,并总结出维护博弈动态均衡的运行机制,以期为中西部地区乃至全国完善农村土地流转提供借鉴和参考。
