0 INTRODUCTION Global warming not only exacerbates the instability of the climate system,causing more weather extremes but also has far-reaching impacts on surface systems,changing disaster environments(Qiu et al.,2024;Ye et al.,2024).The key medium between climate warming and the mountain environment is the cryosphere,whose recession increases the occurrence of chain disasters such as rock-ice avalanches and other flow events(yang et al.,2023).

基于能量平衡原理对近场地震作用下TMD-基础隔震混合控制体系进行了能量响应分析,研究了不同脉冲周期地震作用下混合控制体系的减震效果。采用Bouc-Wen模型模拟隔震层的非线性力-变形行为,建立了TMD-基础隔震混合控制体系的运动方程和相对能量平衡方程。以某八层基础隔震结构为算例,运用四阶龙格-库塔法和梯形法分别对结构安装TMD前后的非线性地震响应和能量响应进行求解,分析了混合控制体系中输入能量的变化和耗散过程。分析结果表明:以隔震层峰值位移作为控制对象时,TMD的控制效果并不好;从能量的角度来看,TMD对主结构的输入能,特别是隔震层滞回耗能的控制非常有效,这是因为TMD的阻尼耗散了体系中的大部分输入能;不同脉冲周期地震作用下TMD的减震效果差别较大,对TMD最优参数进行求解时应考虑地震动特性的影响。

工业烟尘排放时的烟气黑度自动监测对提高环保质量和指导生产过程具有重要的应用价值,针对传统的高斯混合模型在进行背景建模时,参数是在固定帧值的基础上进行参数更新,导致烟尘检测不准确等问题,提出一种自适应变步长高斯混合模型的工业烟尘图像分割方法.根据烟尘变化速度不均匀的特点,通过分析检测出烟尘与实际烟尘的检出率和检准率的和的最大值,计算熵值差变化率对应的最佳步长,得到熵值差变化率与最佳步长的模型.以熵值差变化率为依据,确定最佳步长,得到一个关于熵值差变化率与最佳步长的模型.以熵值差变化率为输入,以最佳步长为输出,在广义回归神经网络(GRNN)得到适用于本文工业烟尘图像分割的网络模型.最后,在多个场景的烟尘视频中进行分割实验,结果表明,本文中方法能够有效的分割出视频中烟尘区域,且具有一定的适用性.
