Phosphorus in energy storage has received widespread attention in recent years. Both the high specific capacity and ion mobility of phosphorus may lead to a breakthrough in energy storage materials. Black phosphorus, an allotrope of phosphorus, has a sheet-like structure similar to graphite. In this review, we describe the structure and properties of black phosphorus and characteristics of the conductive electrode material, including theoretical calculation and analysis. The research progress in various ion batteries, including lithium-sulfur batteries, lithium–air batteries, and supercapacitors, is summarized according to the introduction of black phosphorus materials in different electrochemical applications. Among them, with the introduction of black phosphorus in lithium-ion batteries and sodium-ion batteries, the research on the properties of black phosphorus and carbon composite is introduced. Based on the summary, the future development trend and potential of black phosphorus materials in the field of electrochemistry are analyzed.

以包头市城区综合管廊为研究对象,利用工程场地土的剪切波速等参数,合成基岩地震加速度作为输入地震动时程,并利用Midas GTS NX软件对其进行模拟,得到了土体位移响应、土体加速度响应、管廊加速度响应、管廊相对位移变化以及管廊最大剪应力,并进行了分析。结果表明:土体深度越小,土体加速度放大系数越大;综合管廊各点处加速度时程曲线与输入地震波时程曲线基本吻合;管廊最大剪应力出现在右侧顶板,证明了在地震作用下管廊受土体变形的影响发生了一定的扭曲破坏。因此,在设计、施工过程中应该对管廊的顶板进行重点设计与防护。

介绍经编间隔织物压缩性能的影响因素,分析织物厚度、间隔纱排列方式、倾斜角度、细度与密度和间隔纱原料对间隔织物压缩性能的影响,并论述经编间隔织物压缩性能的测试方法和压缩过程。研究发现,采用较粗的间隔丝、较小的间隔纱倾角和较小的织物厚度有助于增强经编间隔织物的抗压性能,而间隔丝排列密度的增大会直接导致织物克质量的增加,并且间隔织物的纱线原料也需要根据实际的应用要求去选择。
