基于线弹性层状体系理论,采用路面结构有限元法,探讨高等级公路沥青路面剪应力的分布规律、影响因素及其评价方法。通过选取不同路面结构参数,包括各结构层厚度、模量和泊松比等,在不同的点位,利用BISAR程序进行力学计算和分析,提出了... 详细信息

基于线弹性层状体系理论,采用路面结构有限元法,探讨高等级公路沥青路面剪应力的分布规律、影响因素及其评价方法。通过选取不同路面结构参数,包括各结构层厚度、模量和泊松比等,在不同的点位,利用BISAR程序进行力学计算和分析,提出了沥青路面抗剪强度的确定和评价方法。研究结果表明:在不考虑各结构层材料性能和厚度时,最大剪应力均分布在距路表3cm深度范围内;影响剪应力的最主要因素是沥青层模量、泊松比和基层模量;对于普通3层沥青层面层结构,上面层和中面层应进行剪应力验算,下面层可根据实际情况确定是否进行验算;验算时,需找到准确的计算点位才能计算出各层内最大剪应力。

许孚远心性论辨析

中国哲学史 2021年第3期 66-72页

作者：陈鹏聂毅首都师范大学哲学系

许孚远的心性思想主要是在批评阳明后学尤其是现成派王学的背景下形成的。为矫正阳明后学一任灵明、空谈本体之弊,许孚远融气入心,主张心性“非一非二”;标举性体的至尊至善义,力主“无善无恶不可为宗”;并尝试以觉论性。许孚远心性论... 详细信息

许孚远的心性思想主要是在批评阳明后学尤其是现成派王学的背景下形成的。为矫正阳明后学一任灵明、空谈本体之弊,许孚远融气入心,主张心性“非一非二”;标举性体的至尊至善义,力主“无善无恶不可为宗”;并尝试以觉论性。许孚远心性论在整体上显示了综合朱王的思想线索,从修正王学的角度说,它着力于确立心性的客观性维度以及强调“密缮身心”的实修工夫。许孚远修正王学的思想宗旨和庄敬严整的精神气象,对刘宗周产生了深远影响。

在分析和研究了Aihara神经元混沌特性的基础上,建立了基于Aihara混沌神经元的Elman局部递归混沌神经网络(CNN),神经元引入混沌特性后增强了神经网络对非线性映射的全局逼近能力。在船舶大功率同步发电机建模中,以船用柴油机输出转矩功率和发电机输入励磁电流作为CNN建模与辨识的输入参数;以发电机的输出频率、发电机端电压和输出电流作为CNN建模与辨识的输出参数;采用有导师学习方式,运用基于BP的动态训练方法,最终完成了船舶大功率发电机的动态建模。与其它的ANN建模相比较,用CNN建立的模型的隐层神经元数量少,系统的泛化能力强。
