基于图像融合技术与改进Faster R-CNN的绝缘子故障识别

Gaoya dianqi
为提高地铁接触网绝缘子故障检测精度，文中提出一种融合双流注意力生成对抗网络（DSAGAN）与改进Faster R-CNN的检测框架。针对多源图像特征融合难题，通过DSAGAN实现接触网绝缘子红外与可见光图像的高效融合：生成器采用注意力机制强化关键特征提取，判别器引入最小二乘损失函数替代传统交叉熵，有效保留纹理细节并提升网络稳定性。在故障识别阶段，改进Faster R-CNN模型采用ResNet101替代VGG16作为主干网络，结合残差连接缓解梯度异常问题，并在RPN层嵌入非极大值抑制（NMS ...

煤矿区复垦土壤磷有效性对解磷菌肥的响应

Shuitu Baochi Xuebao
目的比较复垦3 a土壤配施解磷菌肥与未配施解磷菌肥对外源磷素吸附解吸特性的影响，研究配施解磷菌肥对复垦土壤磷吸附解吸特性、磷形态和土壤理化性质的作用，为提高磷肥的利用率、快速提升矿区复垦土壤生产力提供理论依据。方法在山西省晋中市榆次区乌金山镇采矿塌陷区复垦试验基地进行试验，共设置7个处理小区，分别为不施肥（CK）、单施化肥（CF）、化肥配施解磷菌肥（CFP）、单施有机肥（M）、有机肥配施解磷菌肥（MP）、化肥有机肥（MCF）和化肥有机肥配施解磷菌肥（MCFP）。采集各处理下土样进行磷吸附动力学试验 ...
