The flow in a liquid falling film is predominantly laminar,and the liquid-side mass transfer is limited by molecular diffusion.The effective way to enhance the mass transfer is to improve the liquid film flow behavior.The falling film behaviors of water,e
预报预警是山洪灾害防治中重要的非工程措施,是防灾减灾救灾的关键环节。选取分别代表秦巴山地水资源保护区、西南地震作用区、喀斯特地区、黄土高原超渗产流区、东南沿海台风影响区的湖北省丹江口官山河流域、四川省都江堰白沙河流域、贵州省望谟县望谟河流域、陕西省子洲县岔巴沟流域、广东省高州市马贵河流域这5个典型流域,通过构建改进的SCS模型进行历史山洪模拟,探讨该模型在小流域暴雨山洪预报预警中的广泛适用性。结果表明:基于SCS模型构建的小流域暴雨山洪预报方案中官山河、白沙河、望谟河、马贵河方案均为乙级方案,可用于正式发
For plant-wide processes with multiple operating conditions,the multimode feature imposes some challenges to conventional monitoring techniques.Hence,to solve this problem,this paper provides a novel local component based principal component analysis(LCPC
基于河道崩岸现有研究成果,对崩岸类型的划分进行了梳理,进而将河道崩岸的影响因素概括为水流动力条件、河道边界条件,及其他因素3大类,并从数值模拟和概化模型试验2个方面总结了河道崩岸研究的进展。在此基础上,分析讨论了当前河道崩岸机理研究中存在的不足,如未能全面考虑各种因素影响、崩岸数值模拟技术不够完善、概化模型试验精度需进一步提高等。最后,对未来崩岸研究工作的开展,提出了需关注的重点与建议。
