In this paper the nano-metric simulation of grinding of copper with diamond abrasive grains, using the molecular dynamics (MD) method, is considered. An MD model of nano-scale grinding, where a single diamond abrasive grain performs cutting of a copper workpiece, is presented. The Morse potential function is used to simulate the interactions between the atoms involved in the procedure. In the proposed model, the abrasive grain follows a curved path with decreasing depth of cut within the workpiece to simulate the actual material removal process. Three different initial depths of cut, namely 4 ?, 8 ? and 12 ?, are tested, and the influence of the depth of cut on chip formation, cutting forces and workpiece temperatures are thoroughly investigated. The simulation results indicate that with the increase of the initial depth of cut, average cutting forces also increase and therefore the temperatures on the machined surface and within the workpiece increase as well. Furthermore, the effects of the different values of the simulation variables on the chip formation mechanism are studied and discussed. With the appropriate modifications, the proposed model can be used for the simulation of various nano-machining processes and operations, in which continuum mechanics cannot be applied or experimental techniques are subjected to limitations.

Farmers are the key agents who manage land and water. Agriculture Green Development (AGD) requires a transformation in farming from high resource consumption and environmental cost to sustainable intensification with high productivity, high resource use efficiency and low environmental risk. This paper analyzes the public policy challenge of AGD and makes the case for a location-sensitive policy mix made up of regulation, advice provision, voluntarism and targeted incentives. The public agricultural extension service in China is a key resource, but one that requires reorientation and reform with the aim of better balancing high farm productivity with environmental protection.

目前在世界范围内的很多地下矿山,岩爆已经成为一个与矿山采矿生产密切相关的重要现象。深入理解这类现象,不仅有助于岩爆管理,而且还有可能节约采矿成本,减少人身伤亡事故。其中,实验室实验是深入研究岩爆机理的一个重要途径。在本文作者前期的研究中,已经建立了实验室岩爆实验数据库。与此同时,借助于数字采矿技术,也建立了岩爆最大应力和岩爆风险指数的预测模型。为实现基于矿山地质条件和矿山井巷建筑结构特性对岩爆类型即岩爆强度等级的准确预测,本文的重点是,基于对岩爆实例的分析来建立岩爆影响矩阵,明确岩爆现象的诱发因子,并厘清这些影响因子之间的相互关系。运用人工神经网络(ANN)和初始贝叶斯分类器等数字矿山技术,对矿山岩爆数据库进行了更深入的研究。最后给出了研究得出的各项结论。
