H2S is well-known as a colorless,acidic gas,with a notoriously rotten-egg smell.It was recently revealed that H2S is also an endogenous signaling molecule that has important biological functions,however,most of its physiology and pathology remains elusive.Therefore,the enthusiasm for H2S research remains.Fluorescence imaging technology is an important tool for H2S biology research.The development of fluorescence imaging technology has realized the study of H2S in subcellular organelles,facilitated by the development of fluorescent probes.The probes reviewed in this paper were categorized according to their chemical mechanism of sensing and were divided into three groups:H2S reducibility-based probes,H2S nucleophilicity-based probes,and metal sulfide precipitation-based probes.The structure of the probes,their sensing mechanism,and imaging results have been discussed in detail.Moreover,we also introduced some probes for hydrogen polysulfides.

短期电力负荷预测在电网安全运行和制定合理调度计划方面发挥着重要作用.为了提高电力负荷时间序列预测的准确度,提出了一种由完整自适应噪声集成经验模态分解(complete ensemble empirical mode decomposition with adaptive noise,CEEMDAN)和基于注意力机制的长短期记忆神经网络(long short-term memory network based on attention mechanism,LSTM-Attention)相结合的短期电力负荷预
以某火力发电厂除尘器后烟道支架的平移改造为例,介绍钢框架结构平移方案的选型,移位前加固措施、荷载取值、基础、下轨道、截断施工、水平移位、就位连接等关键技术.取消托换结构,直接利用原外露式钢柱脚的底板作为滚轴的受力点.启动时用千斤顶进行顶推,移动时用卷扬机牵引,卷扬机反力装置位于烟囱两侧的混凝土烟道支架柱上,成功地一次性平移到位.结构就位后,为便于施工,将钢柱脚改为外包式,混凝土短柱向上延伸包裹钢柱.对于有混凝土楼板的钢结构支架而言,整体平移方案在技术和经济上都优于拆解重建方案.

基于Monin Obukhov相似理论,提出一种以测风塔实测数据为基础筛选中性风速并以此计算地表粗糙度值的方法.相比传统的平坦地形粗糙度划分法中粗糙度取值的不确定性,新方法计算的粗糙度值唯一,而且通过分析计算并与实测值进行对比,结果表明:采用新方法时模拟的风能资源更加接近真实值,计算的粗糙度值准确性较高.
