燃煤电厂海水烟气脱硫工艺原理初探

海水烟气脱硫工艺是利用天然的纯海水（燃煤电厂可直接利用电厂的冷却循环水）作为烟气中ＳＯ２的吸收剂，无需其它任何添加剂，也不产生任何废弃物，具有技术成熟、工艺简单、系统运行可靠、脱硫效率高（理论脱硫效率可达９８％）和投资运行费用低等特点，目前在一些国家和地区已得到日益广泛的应用。本文是在部分模拟试验的基础上，对海水烟气脱硫工艺进行了简单的阐述。     

金属加工过程中应力状态的分析方法

分析简单地拉伸、压缩和扭转的情况时,应力状态能容易地被确定.但是,实际上在金属加工过程中材料是承受复杂的应力状态,在模具——工件接触面上增加有摩擦力.而且,这些应力和摩擦力一般地沿着接触面变化.准确的计算或预测载荷、力、应力和温度,不但对设计适宜的设备是重要的,而且对研究工艺期间材料的变化过程也是重要的.本文将讨论材料变形过程中所运用的主要分析方法及其优缺点.     

中国可持续社会养老保险的综合评价体系和实证分析

我国可持续社会养老保险的综合评价指标体系包括四个层次和三级子系统，内容涉及养老保险人数、机构设置、基金管理和代际平衡四个子目标。应用因子分析模糊综合评价方法对我国1990-2001年养老保险建设状况进行评价，本文认为基金管理，行政管理和代际失衡是影响我国可持续养老保险发展的主要因素。
