Research on Ammonia Emission Inventory in Fujian Province [PDF]
, 2016 近年来，随着福建地区经济快速发展，城市化进度不断加快，环境与经济发展的矛盾日益突出，大气灰霾污染频繁发生，空气质量和能见度下降。氨是大气霾污染生成的促进剂，对大气污染有着直接和间接的影响。本研究建立了福建省人为源氨排放清单，分析氨的排放特征和时空分布，预测未来氨排放水平，探讨氨排放与氨监测和颗粒物离子的关系，为该地区空气质量改善提供了重要的基础数据。 首先，本研究以2013年为基准年，基于排放因子法建立了福建省人为源氨排放清单。研究显示，2013年福建地区人为源氨总排放量是25.24万吨 ...

野生动物学报, 2023 针对使用粪便显微分析法时对食草动物粪便中植物表皮细胞人工分类困难且效率低的问题，提出一种基于多轴注意力的双通道神经网络分类方法，用于自动识别显微镜下食草动物粪便中残留的植物表皮细胞种类。首先，获取粪便中残留的植物表皮细胞图像，作为神经网络模型的输入；引入多轴注意力机制提高网络特征提取能力，同时降低注意力导致的计算复杂度；构建局部和全局通道，提高网络对植物表皮细胞图像信息的获取能力；最后将2个通道提取的特征进行融合，完成对植物种类的识别。此外，应用移动倒置瓶颈卷积（MBConv）模块进行模型的轻量化处理 ...

野生动物学报, 2018 粪便中类固醇激素的水平对动物的繁殖情况具有明确的指示意义。对于虎这一大型食肉动物,利用粪便激素水平来监测其繁殖状态是最为便捷的方式。但是,如果粪便中类固醇激素分布不均匀,不同性状的粪便和不同时间采集的粪便激素含量存在差异,那么在采样时就必须考虑这些因素。本研究用酶联免疫吸附检测法检测了雌性东北虎(Panthera tigris altaica)和华南虎(P.t.amoyensis)粪便中雌二醇、睾酮和孕酮这3种类固醇激素的水平,系统比较粪便表层、中层和中心的差异,不同采集时间所测得激素含量的差异 ...
