| 中文摘要: |
| 目的 探究密封舱室热防护效率与其内饰材料表面发射率的关系，分析内饰材料发射率对其表面温度、舱室内温度的影响规律。方法 采用自行设计的小型密封舱室和加热测量装置，对内饰材料表面及舱室内温度进行测量。结果 当内饰材料发射率为0.09时，内饰表面温度为141.2 ℃，舱室内平均温度仅为90.8 ℃；内饰材料发射率为0.91时，内饰表面温度为124.4 ℃，舱室内平均温度为109.1 ℃。结论 试样表面温度随材料发射率的提高而降低，舱室内部空气平均温度随材料发射率的提高而升高；试样表面温度与舱室空气平均温度的温度差随材料发射率的提高而减小；同时，相同试样表面温度与舱室平均温度的温度差随加热温度的提高而增加。 |

| The work aims to explore the relationship between thermal protection efficiency of sealed cabin and surface emissivity of interior materials, and analyze the influence of emissivity of interior materials on surface temperature and cabin temperature. A small sealed cabin and heating measuring device were designed to measure the surface temperature of interior materials and the interior temperature of cabin. When the emissivity of interior materials was 0.09, the interior surface temperature was 141.2 ℃, and the average temperature in the cabin was only 90.8 ℃. When the emissivity of interior materials was 0.91, the interior surface temperature was 124.4 ℃ and the average temperature in the cabin was 109.1 ℃. The surface temperature of specimen decreases with the increase of material emissivity, but the average air temperature of the cabin increases with the increase of material emissivity. The temperature difference between the surface temperature of the specimen and the average air temperature of the sealed cabin decreases with the increase of material emissivity. Meanwhile, the temperature difference between the surface temperature of the same specimen and the average temperature of the cabin increases as the heating temperature rises. |
