开发了一种可埋置在砂浆内部的宏电池电流传感器。对传感器的阴极与阳极电位,电极间的砂浆电阻以及宏电池电流进行了监测。并针对阳极的不同腐蚀状态,对宏电池电流发生的电化学本质进行了探讨。结果表明,宏电池电流的大小与砂浆电阻、阴极与阳极电位以及阴极阳极的极化电阻之间有直接关系。在阳极处于钝化状态时,宏电池电流几乎可以忽略,这取决于微弱的腐蚀驱动力、较高的电极极化电阻和砂浆电阻。而阳极处于活化状态时,宏电池电流显著增大,此时的腐蚀驱动力较大,而砂浆电阻较小。此外,在活化状态下通过对宏电池电流电化学本质的分析确定了阳极的ln(ia.ic)的值,对砂浆保护层的服役状态和钢筋的腐蚀情况进行了评估。试验结果显示,开发的宏电池电流传感器为钢筋混凝土结构的腐蚀状态进行长期的预警和系统的评价提供新的途径。

在人群计数统计时存在相机透视、人群重叠、人群遮挡等众多干扰因素,使人群计数的准确性不高。针对这一问题,提出一种多尺度融合的深度人群计数算法。首先,利用VGG-16网络的部分结构提取出人群底层特征信息;其次,以膨胀卷积理论为基础,构建多尺度特征提取模块,实现多尺度上下文特征信息的提取,降低模型参数量;最后通过将底层细节特征信息和高层语义特征信息融合的方式,提升模型计数性能和密度图质量。在三个公开数据集上对不同算法进行测试。实验结果表明,与其他人群计数算法相比,所提算法的平均绝对误差和方均误差均有不同程度的降低,说明所提算法具有较好的准确性、鲁棒性及良好的泛化性。
