| 中文摘要:舰船机舱蒸汽管破损是常见的故障，使用热像仪进行蒸汽管破损监测具有重要的应用价值。阐述了日常工作中用热像仪对蒸汽管路进行巡检时的判定标准、监测流程、舱内环境因素对监测的影响及应对措施。日常工作中主要采用直接比较法进行定性判别。监测时，热像仪与被测目标的距离、角度和舱室环境温度对结果判定的影响较小；而其他热源和物体的发射率对结果判定的影响较大。 |

| Abstract:The damage of steam pipes in ship engine rooms is a common fault. The use of thermal imagers is of important value to steam pipe breakage monitoring. The judgment, the monitoring process, the influence of inner environment on monitoring and the corresponding measures when using infrared imagers to monitor steam pipes in daily work are presented. In our daily work, the qualitative judgment is mainly implemented by using a direct-comparison method. During monitoring, the distance between the thermal imager and the target to be measured, the angle of the thermal imager and the ambient temperature in engine compartments have less influences on measurement result judgment. Instead, the emissivity of other heat sources and objects has a great influence on measurement result judgment. |
