禅解赤壁——从赤壁词赋中看苏轼的禅宗思想

＂乌台诗案＂后,仕途上一帆风顺的苏轼被贬黄州。精神的困顿,生活的贫穷,心灵的抑郁,使他转向了宗教,渴求在禅宗里安顿心灵,寻找人生的意义和价值。苏轼接受禅宗的＂明心见性＂,＂不立文字,见性成佛＂,＂五蕴皆空＂,＂心无所住＂,＂人生如梦＂等义理,并将它们与儒道两家融合一体,＂浩然不见其涯也＂。在黄州,在赤壁,苏轼用他的如椽之笔写下三篇赤壁词赋,深刻体现了他对禅宗的认知和体悟。

A novel hybrid solid-like fluid-like (SLFL) method for the simulation of dry granular flows

This paper proposes a novel hybrid method to simulate the dry granular flow of materials over a wide range of inertial numbers that simultaneously covers the quasi-static and dense granular flow regimes. To overcome the lack of incremental objectivity whenever large deformations occur in solid-like regimes and to remove computational singularities in fluid-like regimes close to rest, the elastic–perfectly plastic theory based on the Drucker–Prager yield criterion is combined with the theory of dense granular flows. By implementing some new modifications at the boundaries and removing all ghost particles, smoothed particle hydrodynamics (SPH) is used as the framework for the method. A number of benchmark problems have been solved to show the capabilities of the new modified SPH method. Precise prediction of both location and pressure makes the modifications comparable with the previous works on SPH. Finally, the method is used to solve the classic 2D dry granular cliff collapse problem and to model dry granular material flow inside a rotary drum. The outcomes of the numerical simulation show good agreement with tabletop experiments and published results.     

链子崖危岩体T8──T12缝段开裂变形机制的研究

文章通过对煤层采空区的分布、地压作用、山体开裂和近２０多年来的变形等方面的综合分析，得出链子崖危岩体具有南北强拉裂、东西弱拉裂和平面反时针转动的立体开裂变形机制。据此，作者进行了有针对性的计算，为危岩体综合加固体系的建立提供了依据。     

恩施悬棺人骨mtDNA初步分析

本文以恩施宋代悬棺的骨骼或牙齿样品为对象,经过一系列的处理,获得并扩增了mtDNA的HVSI区的部分序列,通过几个实验初步认定是古DNA.同时通过与部分现代人mtDNA数据的比较参照,对所研究样品单倍群归属进行了初步确定,发现他们主要属于南方类型,但也可能有北方成分.     

泰山扇子崖信仰活动考释

扇子崖为泰山西南一区,明中期以前可勾勒的历史基本与兵事相关;明清之际及以后,扇子崖突出的事象是信仰活动的肇兴及发展。虽然从现存史籍、传说、碑记等资料中难窥当时全貌,但结合泰山扇子崖民间信仰的现状,对其信仰活动肇兴之时的探索依然具有重要意义。结合历史背景梳理泰山扇子崖的历史,描述信仰活动的肇兴,以为泰山扇子崖信仰活动的现状及转变等研究略述缘由。
