基于VR技术的机场应急救援虚拟演练平台

为解决机场实地应急演练中存在的成本消耗高、不安全、扩展性差等问题,研发基于VR技术的机场应急救援虚拟演练平台。平台采用模块化设计方案,并通过定义平台操作流程支持虚拟演练操作。采取分细节度的场景构建方法,运用细节层次模型以3层不同细节度模型方案将虚拟灾害场景划分为3类,同时利用Unity3D粒子系统控制机制实现火灾及灭火粒子特效的模拟,运用双顶层本体模型构建机场应急预案本体模型（AERPO）,并利用XML Spy建立存储模型,且支持基于典型场景模型编辑形成整个灾害场景。结果表明:平台模块设置科学、场景效果合理,有助于提升演练人员应急处置能力。

经济与环境协调发展综合指标与实证分析

贯彻落实科学发展观,其重要内容之一就是要实现经济与环境的协调发展.建立了体现经济与环境协调关系的5个单项指标,即能耗强度、水耗强度、污染物(SO2和COD)排放强度、运输强度、环保投入强度,以及1个综合性指标--经济与环境协调度.以上述指标为基础,比较分析了代表我国东部及中、西部地区经济发展水平的广东省、湖北省和陕西省1999-2003年经济与环境关系现状.结果表明:东部发达地区经济与环境日趋协调,而中、西部地区经济与环境关系协调度较差,尤其是西部地区表现尤为明显.

Quantity and biochemical composition of sedimentary organic matter around offshore gas extraction platforms of the Adriatic Sea

Gas platforms can exert relevant effects on various ecosystem properties of the hosting area, modifying patterns of productivity and particle sedimentation. We hypothesised that the presence of gas platforms is associated with higher organic matter (OM) contents and we tested the null hypothesis by which benthic trophic conditions do not vary significantly among gas structures with different architectural characteristics. To test these hypotheses, we investigated sedimentary OM contents and biochemical composition at increasing distance from two distinct structures: one subsea well-site and one four-leg platform (FLP). We found that sediments surrounding the structures were characterised by similar OM contents, but different biochemical compositions, and that sedimentary OM compositional change with increasing distance from the structure is confirmed only at the FLP. These results suggest that: (i) benthic eutrophication is not consistent among different structures; (ii) OM biochemical composition changes are more evident than those in OM quantity; and (iii) the effect, wherever present, disappears at a very narrow distance from the platform. As biochemical composition of OM reflects food availability for benthic organisms, our results suggest that the enrichment of macrozoobenthic communities around these structures could be the consequence of increased nutritional quality of resources.

Gas/particle partitioning of atmospheric PCDD/Fs in a satellite town in Eastern China

Gas/particle partitioning of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in ambient air was investigated in a satellite town in Eastern China from April 2007 to January 2008 comprehending large temperature variations (from 3 to 34 °C, daily average). Molecular weight, molecular structure and ambient temperatures are the three major factors that govern the gas/particle partitioning of atmospheric PCDD/Fs throughout the year. Generally, good agreements were obtained (except for winter) between measured particulate fractions and theoretical estimates of both the Junge–Pankow adsorption model and Harner Bidleman absorption model using different sets of subcooled liquid vapor pressure and octanol–air partition coefficient (K_oa), respectively. Models utilizing estimates, derived from gas chromatographic retention indices (GC-RIs), are more accurate than that of entropy-based. Moreover, during winter, the K_oa-based model using the GC-RIs approach performs better on lower chlorinated PCDD/Fs than that of -based. Furthermore, possible sources of mismatch between measured and predicted values in winter (3–7 °C) were discussed. Gas adsorption artifact was demonstrated to be of minor importance for the phenomena observed. On the other hand, large deviations of slopes (m_r) and intercepts (b_r) in logK_p vs. plots from theoretical values are observed in the literature data and these are found to be linearly correlated with ambient temperatures (P<0.001) in this study. This indicates that the non-equilibrium partitioning of PCDD/Fs in winter may be significantly influenced by the colder temperatures that may have slowed down the exchange between gaseous and particulate fractions.
