为解决交叉口风险评估未充分考虑驾驶员状态和风险损失的问题,提出了一种综合风险概率和风险损失的风险评估方法。利用熵值法得出基于驾驶员生理信息的风险概率,基于能量转换定理确定直接风险损失,提出环境脆弱度确定间接风险损失;利用聚类算法得到风险损失和风险概率的等级,进而基于风险矩阵得到交叉口风险等级。分析西安市19个交叉口试验数据得出:交叉口风险等级划分为比较安全、一般安全、比较风险和非常风险4个等级,风险等级主要集中在比较风险级别。所提出的基于驾驶员生理信息的交叉口风险评估方法与试验驾驶员的感知相符,准确度达到90%,为驾驶员风险管理提供了新方法。

目的探讨接受经皮冠状动脉介入治疗(PCI)伴多支病变高龄冠心病患者达到完全血运重建(CR)或部分血运重建(ICR)对临床预后的影响。方法连续纳入2015年1月至2015年9月确诊为冠状动脉多支病变并接受PCI高龄患者(≥75岁)257例,根据PCI情况分为CR组与ICR组。对比两组患者临床基本资料、PCI情况、院内及随访期间主要心脑血管不良事件(MACCE)。结果 CR组患者171例(66.53%),ICR组患者86例(33.47%)。ICR组患者伴有高血压病史、糖尿病病史,入院诊断急性非ST段抬高型心肌梗死、闭塞病变,术后1、3个月出现胸闷、心慌等不适症状及二次住院率比例均明显高于CR组(P0.05)。结论伴多支病变高龄冠心病患者ICR并未增加PCI术后MACCE风险,但二次住院率与术后不适症状发生率增加,远期预后有待进一步观察。

用热重分析法测量了中温(400-800℃)烟气固硫新型钙基吸收剂的钙转化率。在最初的几分钟内,钙转化率增加迅速,产物层形成后基本不再增加。固硫反应速率随温度升高而增大。一定温度下的速率先增加后减少最后趋于平缓．这是由气相在吸收剂颗粒间的扩散和在产物层内的扩散引起的。热重试验与流化床脱硫的主要区别在于气相颗粒间扩散以及由此引起的反应表面SO2浓度不同．提出了表观反应的概念,以便建立模型并向流化床状态过渡。
