Monitor the Entire Risk Management System of the Custody Business of Commercial Banks

随着经济全球化趋势的进一步加强,我国商业银行的发展也正在与世界接轨,其中托管业务的开展就是与国际接轨的一个直接证明.同时,由于国际竞争的越发激烈,境外机构纷纷把中国作为将来的主要市场,这对我国的商业银行是一个巨大的挑战.所以我国的商业银行要理顺发展思路,重新构建托管业务监控体系,来应对即将到来的竞争.     

Discovery of Late Carboniferous strata and their tectonic significance in the southern margin of the North China Block （Huoqiu and Gushi areas）

Late Carboniferous fossils （such as Boultonia？ sp., Tabulata, and spiriferoid specimens with smooth she/Is）, bioclastic material （such as crinoid stems and sponge fragments）, and Late Ordovician microfossils of the conodont Belodina have been discovered in the lower part of the strata typically referred to as the Neoproterozoic on the boundary of the provinces of Anhui and Henan in the southern margin of the North China Block. These findings prove that the strata contain macrofossils belonging to the Late Carboniferous, which belonged to a carbonate debris flow deposit that was formed under a carbonate slope environment. The conodont fossils might belong to a detrital deposit. Thus, it is possible to reset the stratigraphic sequences and tectonic attributes belonging to the North Huaiyang tectonic belt and limit the Shouxian fault to the boundary between the Dabie Orogen and North China Block.     

深圳红树林自然保护区海水重金属质量评价

为保护红树林海域环境，改善海水质量，对深圳红树林自然保护区16个样点进行海水采集，样品通过ME ICP41W测定Hg、Cd、As、Pb、Cu、Cr含量，并基于Hakanson指数法和倍斜率隶属函数聚类法评价海水质量.评价结果显示:深圳红树林自然保护区海水中Hg属于“极强生态危害元素”，As属于“强生态危害元素”，Cd属于“中等生态危害元素”，Pb、Cu、Cr属于“轻微生态危害元素”；海水整体上属于“很强生态危害”范畴，但以一类海水为主，部分靠近河涌排污口的样点为二类和四类海水；重金属主要来源于生活和工业废水，Pb、Cu、Cr、Cd共同的污染源来自调查区周边的合金制造厂和印刷厂；Hakanson指数法和倍斜率隶属函数聚类法对海水质量的评价结果相关性高，表明所采用的评价方法可行.该研究对深圳红树林自然保护区海域保护和海水重金属评价方法具有参考价值.     

林下山参生长指标与土壤性状的灰色关联度和通径分析

应用灰色关联度和通径分析方法对长白山地区林下山参地上部分8个生长指标与16个土壤性状因子之间进行了关联分析。经灰色关联度分析得出了林下山参生长指标与土壤性状的关联序; 通径分析得出了林下山参生长指标与土壤性状因子的关联趋同。结果表明,土壤全硫和有效锌是林下山参成活与生长的重要限定性因子。因此,生产中可通过提高林下土壤中全硫和有效锌的含量来增加林下山参的保存率并促进林下山参生长。

基于排队论的城市路网模式选择

假设相同道路用地面积下的4种路网模式,基于交通工程学的基础理论之一,排队论,分别计算并讨论以下两种情形4种路网模式中车流沿横向或纵向行驶产生的总耗时变化趋势:到达率相同,道路用地面积率持续变化;道路用地面积率相同,到达率持续变化.并对总耗时和趋势变化曲线进行比较、分析.结果表明:车流到达率不高,即交通量不大的情况下,低密度、红线较宽的路网模式(模式1)具备一定优势;当交通量增多和出现拥堵时,高密度的单行线路网系统(模式4)更具优势.关键结论可直接指导规划实践.     

Kinetic calculations for the thermal decomposition of calcium propionate under non-isothermal conditions

Calcium propionate (CP) is shown to be useful for simultaneous SO2/NO reduction in coal-fired power plants and its thermal decomposition characteristics are measured by thermogravimetric analysis in a feasibility study into more complete reduction of these hazardous gases. Calcium carbonate (CC), which has been used primarily for in-furnace desulfuration, was used for comparison. The thermal decomposition of this organic calcium-based sorbent began at low temperature, i.e. the carboxylic radical was evaporated from 565 K to 759 K for CP and the corresponding mass loss percentage was 47.79%. The residual was subsequently decomposed to release carbon dioxide between 843 K and 1012 K. The latter phase of the process occurred more readily than with CC because of the loose structure of CP resulting from evaporation of the carboxylic radical in the low temperature zone, which could be seen directly by scanning electron microscope. The maximum mass loss rates of this phase occurred at temperatures of 972 K and 1012 K for CP and CC, respectively. The Ozawa-Flynn-Wall method was used to calculate the activation energy during the thermal decomposition process at heating rates of 5, 7.5, 10 and 15 K/min. The result further confirmed the multistage characteristic of CP thermal decomposition, which could be seen in differential thermogravimetry curves. The reaction orders of CP in the conversion range 20%-80%, calculated using the Avrami theory were from 0.061 to 0.608, smaller than those of CC, which were 1.647 to 2.084.
