高校实验室爆炸事故致因定量分析方法研究

为揭示高校实验室爆炸事故致因因子间的相互关系,进而为高校实验室精准化管理提供科学依据,本文采用一种基于24Model的定量分析方法,用于剖析高校实验室爆炸事故致因因子间的逻辑关系和属性特征。本研究首先基于24Model的原因模块辨识实验室爆炸事故致因;然后利用序关系分析法确定各致因的权重,结合DEMATEL-ISM方法对实验室爆炸事故的复杂逻辑关系进行层级划分;最后运用MICMAC方法识别实验室爆炸事故致因的属性特征。通过将上述方法运用于南京航空航天大学实验室爆炸事故分析,结果表明：在教育行政部门安全监管体系存在缺陷等外部独立致因的负面影响下,安全投入认识等组织自发致因受到负作用,进而促使违规进行操作等个体依赖致因涌现,最终导致实验室爆炸事故的发生。

Regeneration of 2-amino-2-methyl-1-propanol used for carbon dioxide absorption

To improve the efficiency of the carbon dioxide cycling process and to reduce the regeneration energy consumption, a sterically hindered amine of 2-amino-2-methyl-1-propranol (AMP) was investigated to determine its regeneration behavior as a CO_2 absorbent. The CO_2 absorption and amine regeneration characteristics were experimentally examined under various operating conditions. The regeneration efficiency increased from 86.2% to 98.3% during the temperature range of 358 to 403 K. The most suitable regeneration temperature for AMP was 383 K, in this experiment condition, and the regeneration efficiency of absorption/regeneration runs descended from 98.3% to 94.0%. A number of heat-stable salts (HSS) could cause a reduction in CO_2 absorption capacity and regeneration efficiency. The results indicated that aqueous AMP was easier to regenerate with less loss of absorption capacity than other amines, such as, monoethanolamine (MEA), diethanolamine (DEA), diethylenetriamine (DETA), and N-methyldiethanolamine (MDEA).     

Effects of low temperature on aluminum(Ⅲ) hydrolysis:Theoretical and experimental studies

In this study,the effects of low temperature on aluminum(Ⅲ)(Al)hydrolysis were examined both theoretically and experimentally by constructing a solubility diagram for amorphous aluminum hydroxide(Al(OH)_3(am))and a distribution diagram of hydrolyzed Al species.First,thermodynamic data of Al species at 4℃were calculated from that at 25℃.A well confirmed polymeric Al species, AlO_4Al_(12)(OH)_(24)~(7+)(Al_(13)),was involved in building the diagrams and,correspondingly,the non-linear simultaneous equations ...     

Estimation of vegetative mercury emissions in China

Vegetative mercury emissions were estimated within the framework of Biogenic Emission Inventory System (BEIS3 V3.11). In this estimation, the 19 categories of U.S. Geological Survey landcover data were incorporated to generate the vegetation-specific mercury emissions in a 81-km Lambert Conformal model grid covering the total Chinese continent. The surface temperature and cloud-corrected solar radiation from a Mesoscale Meteorological model (MM5) were retrieved and used for calculating the diurnal variation...
