目的:含氟废物焚烧过程排放的氟化物会危害人体健康,造成环境污染。本文旨在探究含氟废物焚烧过程中氟的析出特性、氟在焚烧系统中的分布特征以及氟在焚烧灰渣中的赋存形态。这对评估含氟废物在焚烧过程中造成的氟污染以及污染控制具有重要意义。创新点:1.系统研究了氟在焚烧过程中的释放特征以及氟在整个焚烧系统中的质量流,对评估焚烧过程中的氟污染及污染控制具有重要意义;2.系统研究了焚烧灰渣中氟的赋存形态,为后续灰渣中氟污染控制研究奠定基础。方法:1.采用热重红外联用方法,分析研究含氟废物热解过程中氟的析出特性(图4和6);2.采用高温燃烧水解-离子色谱的方法,测定焚烧灰渣中的氟含量,并结合灰渣量等数据,得到氟在焚烧系统的分布特征(图10和11);3.采用连续化学萃取法,得到焚烧灰渣中氟的赋存形态(图12和13)。结论:1.热解过程中,含氟废物中氟主要以氟化氢和氟化硅形式释放;氟化氢的释放可以分为3个温度区:123.5~757.5°C、757.5~959.6°C及959.6°C以上;氟化硅的释放主要集中在132.6~684.0°C。2.焚烧过程中,超过79.17%的氟被湿法脱酸系统吸收,不到20.73%的氟存在于焚烧灰渣中;排放到大气中的氟占比小于0.12%。3.底渣和燃尽室灰中的氟主要以残余态存在;余热锅炉灰和布袋飞灰中水溶态、交换态和酸溶态氟的比例之和均在80%以上。

目的针对从原发性肝癌中检测肝细胞癌(HCC)的灵敏度不高和诊断结果高度依赖放射科医生的专业性和临床经验,本文利用深度卷积神经网络(CNN)的方法自动学习B超和超声造影(CEUS)图像中的特征信息,并实现对肝癌的分类。方法建立并验证基于CNN的多个二维(2D)和三维(3D)分类模型,分别对116例患者(其中100例HCC和16例非HCC)的B超和CEUS影像进行定量分析,并对比分析各个模型的分类性能。结果实验结果表明,3D-CNN模型的各方面性能指标都优于2D-CNN模型,验证了3D-CNN模型能同时提取肿瘤区域的2D影像特征及血流时间动态变化特征,比2D-CNN模型更适用于HCC与非HCC分类。其中3D-CNN模型的AUC、准确率和敏感度值最高,分别达到了85%、85%和80%。此外,由于HCC和非HCC样本不均衡,通过扩充非HCC样本的数量可以提升网络的分类性能。结论本文提出的3D-CNN模型能够实现快速、准确的肝癌分类,有望应用于辅助临床医师诊断与治疗肝癌。
