Таким образом выделена линия поглощения и точно измерена концентрация C2H4. Максимальные погрешности газометрического анализа C2H4 и CH4 5.3×10–6/201.7×10–6 и 57×10–6/5000×10–6. Предлагаемый способ эффективно устраняет ошибки, вызванные перекрестной интерференцией линий поглощения C2H4 в ближнем ИК-диапазоне, и повышает точность системы обнаружения газа TDLAS. </p></abstract><trans-abstract xml:lang="en"><p>To tackle the cross-interference problem between CH4 and C2H4 and the aliasing interference problem of C2H4 itself, on the basis of the sparse decomposition theory, multiple Lorentz function-based methods were proposed for separating the cross-aliasing interference of near-infrared (IR) C2H4 absorption lines. A quadruple Lorentz function-based separation model describing the absorption coefficient of C2H4 is developed, with which the absorption lines of background gas and to-be-measured C2H4 were separated from the absorption lines of mixed gas, thereby effectively separating the absorption line of C2H4 and accurately measuring its concentration. The results show that the maximum errors of C2H4 and CH4 gasometrical analyses are 5.3×10−6/201.7×10−6 and 57×10−6/5000×10−6, respectively. The proposed method effectively eliminates the errors caused by cross-aliasing interference of C2H4 absorption lines in the near-IR bands and improves the detection accuracy of the TDLAS gas detection system. The findings of this study provide a feasible solution to the cross-aliasing interference problem of IR absorption lines. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>самовозгорание угля</kwd><kwd>репрезентативный газ</kwd><kwd>C2H4</kwd><kwd>линия поглощения</kwd><kwd>интерференция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coal spontaneous combustion</kwd><kwd>representative gas</kwd><kwd>C2H4</kwd><kwd>absorption line</kwd><kwd>aliasing interference</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the National Key R &amp; D Plan of China (No. 2021YFE0105000), the National Natural Science Foundation of China (No. 52074213), Shaanxi Key R &amp; D Plan Project (Nos. 2021SF-472 and 2021GY-131), Yulin Science and Technology Plan Project (Nos.
