Preparation of phenolic resin derived 3-D ordered macroporous carbon

Three-dimensionally ordered long-range macroporous carbon structures were prepared using commercially available phenolic resin by utilizing sacrificial colloidal silica crystalline arrays as templates that were subsequently removed by HF etching after pyrolysis in an argon atmosphere. SEM, TEM, and BET were employed to characterize the morphology and the surface area of the porous carbon structures. The pore size (150–1000 nm) and BET surface area, which reflect pore volume (298.6 m²/g (1.32 cm³/g) ∼ 93.7 m²/g (0.12 cm³/g)), of the macroporous carbon structures produced were approximately proportional to the size (150–1000 nm) of the sacrificial silica sphere templates used (annealing temp. 550°C). The achieved 550 nm porous carbon structures were examined to function as potential catalyst carriers and were successfully impregnated with Ag or Pt-Ru on their inner walls after borohydride reduction at room temperature. In addition, porous carbon patterns were fabricated using the ‘micromolding in capillary’ technique, which has potential applications in the microreaction technology.     

基于PXI总线的LVDS数据采集存储模块的设计

鉴于SAR原始数据量大以及数据传输速率限制的问题,设计了基于PXI的雷达回波和图像数据实时记录模块。大容量数据采集记录系统基于通用的商业PC平台设计,选用FPGA作为主控芯片对电路整体逻辑进行控制;利用LVDS作为数据传输接口对数据进行接收,实现了数据采集、缓存以及通过PXI总线上传至上位机硬盘,以便后续处理。文中介绍了系统方案的总体设计,以及采集存储硬件电路的设计,并对电路的关键技术给以详细的分析。

Application of open-pit and underground mining technology for residual coal of end slopes

Given the conditions of residual coal from the boundary of a flat dipping open-pit mine,which uses strip areas mining and inner dumping with slope-covering,we propose an open-pit and underground integrated mining technology for residual coal of end slopes.In the proposal a conveyance road and ventilation conveyance near the slope are built,corresponding to the pit mining area and the surface coal mine dump,as well as an interval haulage tunnel and air-inlet tunnel.The outcome shows that such mining method may reduce the effect to slope stability from underground mining,it does not affect the dumping advance and has a high recovery rate of residual coal resources.The working face is timbered by single hydraulic props,transported by a scraper conveyor and supported by coal walls.This method of mining is one of layered top coal caving,with high resource recovery,low production cost where positive economic benefit can be realized.

证券投资学课程实践性教学模式探析

证券投资学是一门实践性很强的专业课程,目前证券投资学实践教学存在内容陈旧、重视程度不够、实践教学的平台建设落后等诸多问题。针对问题,必须对证券投资学实践教学的具体内容重新进行设计,如建立证券模拟实训室、案例交往与实践性教学有机结合、加大证券投资学实践性教学的分量等措施。主要目的在于缩短证券投资理论与实践之间的距离,从而培养高素质的证券投资应用型人才。
