Gas leak infrared imaging detection technology has become one of the most effective means to detect gas leaks. We propose a novel MRGC (minimum resolvable gas concentration) model that is suitable for evaluating the performance of passive GLIIDSs (gas leak infrared imaging detection systems). An MRGC equivalent calculation method and a direct MRGC measurement method based on the MRTD (minimum resolvable temperature difference) model are also proposed. The MRGC measurement system is designed and built. The measured and calculated results are in good agreement, which verifies the MRGC model's correctness and demonstrates the effectiveness of the MRGC performance evaluation method.
气体泄漏红外成像检测技术已成为检测气体泄漏最有效的手段之一。我们提出了一种适用于评估被动式气体泄漏红外成像检测系统性能的新型最小可分辨气体浓度（MRGC）模型。还提出了基于最小可分辨温差（MRTD）模型的MRGC等效计算方法和直接MRGC测量方法。设计并构建了MRGC测量系统。测量结果与计算结果吻合良好，验证了MRGC模型的正确性，证明了MRGC性能评估方法的有效性。
