Breakage is an important step in the resource processing chain.However,the mechanical crushing methods commonly used today suffer from low energy efficiency and high dust levels.Promoting environmental protection and improving energy efficiency are crucial to advancing China’s circular economy.Mining companies are actively exploring novel and innovative technologies to significantly cut down on operating costs and minimize emissions of dust and pollutants generated during processing.Recently,high voltage pulse discharge(HVPD)technology has received widespread attention and has been reported to have good application prospects in resource processing.This paper presents an extensive review of the operational principles of HVPD and the unique characteristics it engenders,such as non-polluting,selective material fragmentation,pre-weakening,pre-concentration,and enhanced permeability of coal seams.Additionally,this review explores the potential and obstacles confronting HVPD in industrial contexts,offering fresh insights for HVPD optimization and providing guidance and prospects for industrial deployment and further development. 展开更多

在工程腐败案件中,行贿人与受贿人经历了相识期、暧昧期和交易期的博弈过程。从理性经济人的角度分析,行贿人行贿是一种低成本高回报的"明智投资",受贿人的受贿是一种低风险高收益的"理性选择",他们的选择符合经济... 在工程腐败案件中,行贿人与受贿人经历了相识期、暧昧期和交易期的博弈过程。从理性经济人的角度分析,行贿人行贿是一种低成本高回报的"明智投资",受贿人的受贿是一种低风险高收益的"理性选择",他们的选择符合经济理性。行贿人与受贿人的理性选择背后,折射出的是制度上的漏洞,为此,要分散权力,细化制度,减少寻租空间;健全法律,严密法网,预防与惩罚并重;转变观念,加强教育,对腐败"零容忍"。 展开更多
