Purification effect of ex-situ ecological combined remediation system on different forms of phosphorus in tributaries of Jiulong River(异位生态组合修复系统对九龙江支流水体不同形态磷的净化效果)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
采用异位生态组合修复系统研究九龙江支流浦林溪污染水体不同形态磷净化效果及其对磷形态百分比的影响,并分析了异位生态组合修复系统各处理单元水体磷形态与环境因子的相关性。结果表明,异位生态组合修复系统对总磷(TP)、溶解态总磷(DTP)、可溶性正磷酸盐(DP)和颗粒态磷(PP)的平均总去除率分别为84.3%、84.4%、90.8%和78.9%,其中对DP净化效果最好。在异位生态组合修复系统各处理单元中,当原水水体中磷浓度较低时,泥膜共生高效混凝净水系统对TP、DTP和DP的净化效果良好,平均去除率分别可达81.

基于多尺度特征融合的轻量化人脸图像修复算法

open access: yesDianxin kexue
针对当前遮挡的人脸图像修复中修复图像质量差和模型参数量大的问题,提出了一种基于多尺度特征融合的改进U-Net的轻量化人脸图像修复模型——LM-UNET。首先,使用深度可分离卷积替换原有卷积,增强模型对不同通道和上下文信息的特征表达能力,实现模型轻量化;其次,在跳跃连接中设计了多尺度特征注意力融合模块,充分融合不同尺度特征的信息,内嵌残差块减少特征间语义差距,提高模型修复准确率;最后,引入了位置注意力模块,增强人脸图像的显著信息,提升模型对人脸位置像素信息的有效提取能力。在基于CK ...
