对3种煤自燃倾向性的测定样品进行常规包装和除氧包装方式的长期稳定性研究，考察氧化作用对煤样吸氧含量值的影响程度，最终确定采用常规包装作为样品的贮存方式。常规包装的煤样吸氧含量值稳定性可达一年以上，为煤自燃倾向性标准物质的可行性研制提供了技术依据。
對3種煤自燃傾嚮性的測定樣品進行常規包裝和除氧包裝方式的長期穩定性研究，攷察氧化作用對煤樣吸氧含量值的影響程度，最終確定採用常規包裝作為樣品的貯存方式。常規包裝的煤樣吸氧含量值穩定性可達一年以上，為煤自燃傾嚮性標準物質的可行性研製提供瞭技術依據。

For 3 types of coal spontaneous combustion tendency samples,the stability in long term of both using regular packaging method and deoxidation packaging method was researched,the effect of oxidation on the adsorbed oxygen content of coal sample was evaluated,in conclusion,normal packaging storage method was selected finally.The stability period of adsorbed oxygen content value of regular packaging samples could reach more than one year.It provided the technical basis for feasibility of the reference material of coal spontaneous combustion tendency.
