BIM模型不支持有限元计算,且BIM模型与有限元分析模型数据交互困难,故BIM技术正向设计过程中存在建模效率低、模型修改困难等问题,无法做到BIM结构设计与有限元力学分析一体化,增加了结构模型建模与纠错成本.本文依托Revit和Midas/Civil软件平台,在Dynamo环境下采用IronPython语言设计了一套Revit-Midas/Civil的模型信息转换程序.以博士大桥主桥为对象,通过程序自动实现:1)Revit模型桥梁构件分解、截面特性计算、拉索及梁塔弹性连接处理,并转换成适用于Midas/Civil的语言格式MCT文件,实现了Revit向Midas/Civil模型信息自动转换;2)将有限元计算结果反馈到Revit模型中,对作用效应信息按数值大小赋予渐变颜色,实现了在BIM模型中显示有限元分析结果的展示功能.本文程序可实现Revit-Midas/Civil模型信息转换,有效提高了BIM正向应用效率,弥补了BIM技术在桥梁结构分析方面的不足.

对流层臭氧是一种污染气体,也是重要的温室气体,它可以影响人类健康、严重危害生态环境。本研究利用WOUDC(The World Ozone and Ultraviolet Radiation Data Centre)发布的臭氧探空观测数据,评估了2007-2018年北半球地区GOME-2A(Global Ozone Monitoring Experiment 2 aboard METOP-A)、OMI(Ozone Monitoring Instrument)卫星的对流层臭氧柱含量产品以及TCR-2(Updated Tropospheric Chemistry Reanalysis)再分析对流层臭氧产品。分析结果表明,在赤道美洲地区、亚热带地区、欧洲西部和加拿大地区,GOME-2A与探空观测之间的相关系数最高可达0.56,相对偏差百分比绝对值不超过15%;在加拿大地区、美国东部地区和欧洲西部地区,OMI与探空观测之间的相关系数为0.65~0.72,标准化的均方根误差为0.47~0.56;就整个北半球区域而言,TCR-2对流层臭氧柱含量与探空观测之间的相关系数为0.41~0.95,标准化的均方根误差为0.18~0.48,优于其他两种卫星资料。此外,进一步探讨对流层臭氧柱含量趋势结果发现,TCR-2对流层臭氧柱含量变化趋势与探空观测结果较为一致。利用评估后的数据进一步分析发现,在赤道美洲地区、欧洲西部地区和中国地区对流层臭氧柱含量增加,而近年来在北极地区、加拿大地区和美国东部地区对流层臭氧柱含量减少。

煤灰的熔融特性是气化用煤的重要指标,添加助熔剂是降低高灰熔点煤灰熔融温度的主要方法。复合助熔剂可利用不同组分间的协同作用,显著降低助熔剂添加量,提高煤气化整体效率。选取钢渣(GZ)和赤泥(CN)两种工业固废制备复合助熔剂,考察气化条件下复合助熔剂对高灰熔点潞安煤(LA)灰熔融特性的影响,并分析了高温下煤灰中矿物质的变化。结果表明:添加量为2%~8%的钢渣、赤泥和钢渣与赤泥制备的复合助熔剂,均能降低潞安煤灰的熔融温度,且随钢渣与赤泥混合质量比的增加,潞安煤灰的熔融特征温度呈“V”型变化;钢渣与赤泥对降低潞安煤灰的熔融特征温度存在显著的协同作用,且协同作用与添加量、钢渣与赤泥的混合质量比密切相关;添加量为2%与混合质量比为9∶1、添加量为4%与混合质量比大于5∶5、添加量为6%和8%与所有混合质量比条件下,添加复合助熔剂后潞安煤灰的熔融特征温度均低于单独添加钢渣、赤泥后潞安煤灰的熔融特征温度。高温下潞安煤灰矿物质组成表明,添加量为2%与混合质量比为9∶1,添加复合助熔剂显著降低了潞安煤灰中莫来石和硅线石的含量;添加量为4%~8%,高温下潞安煤灰中钠长石与钙长石、方钙石、钙铝黄长石等含钙矿物质发生低温共熔,这是复合助熔剂对降低潞安煤灰熔融特征温度存在协同作用的根本原因。
