| 中文摘要: |
| 系统梳理2005年以来橡胶混凝土界面过渡区（ITZ）原位表征研究，从纳米成核、微米孔隙到毫米裂缝，构建“时间-空间-化学”三元演化框架。总结环境扫描电子显微镜（ESEM）、原子力显微镜（AFM）-拉曼-荧光三合一、微焦点-中子-同步辐射四维计算机断层扫描（4D CT）及X射线吸收近边结构（XANES）-电化学阻抗谱（EIS）等多模态联用进展，阐明“低成核-高取向-大孔隙”三相特征与强度损失的定量耦合，指出跨尺度本构缺失、运动伪影和现场尺寸瓶颈三大挑战。展望AFM-拉曼-荧光探针、深度学习实时分割、150 mm中子加载框架与标准样品库，为实现橡胶混凝土由低强度利用转向高韧性设计提供参考。 |

| In-situ characterization research on the interfacial transition zone（ITZ） of rubberized concrete since 2005 was systematically reviewed.From nano-scale nucleation，micro-scale porosity，to millimeter-scale cracking，a tripartite evolutionary framework encompassing time-space-chemistry was constructed.The latest progress in multi-modal coupling techniques，including environmental scanning electron microscope（ESEM），atomic force microscope（AFM）-Raman-Fluorescence tri-modal probes，micro-CT/neutron/synchrotron four dimensional computed tomography（4D CT），and X-ray absorption near edge structure（XANES）-electrical impedance scanning（EIS），was summarized.The quantitative coupling between the tri-phase characteristics of low nucleation density，high crystal orientation，and high porosity and the macroscopic strength loss was elucidated.Three major challenges were identified：the lack of a cross-scale constitutive model，motion artifacts in imaging，and the bottleneck of limited sample size in laboratory testing.Prospects were directed towards integrated AFM-Raman-Fluorescence probes，deep learning-based real-time segmentation，a 150 mm neutron loading framework，and the establishment of standard sample library.This review provided a reference for transitioning rubberized concrete from low-strength utilization towards high-toughness design. |
