摘　　要：选择常见的普通粘土砖作为研究对象,利用一体化高温炉、自制玻璃单面辐射试验台模拟火场的热环境,分别制备了常温、均匀受热、单面受热、自然冷却、流水冷却后粘土砖试样,观察其表面和内部的宏观、微观痕迹特征,分析总结出不同温度、不同受热面、不同冷却方式下粘土砖的痕迹特征规律。Choosing the general common bricks as object of study, an experiment was carried out to simulate the thermal environment by using integral high-temperature furnace and one-sided radiation of self-made glass. Brick samples were separately made in room temperature with even heating, one-side heating, natural cooling and floating cooling. The characteristics of bricks in different temperature, different cooling methods and different heating methods were summarized on the basis of their macroscopic and microscopic trace features observed.
