通过Ａｌｔｅｒｎａｒｉａ ｔｅｎｕｉｓ 菌孢的实验室热模拟试验，进行了菌孢反射率、荧光、有机差热及Ｘ射线衍射等测试分析。在热演化过程中， 菌孢的菌孢反射率随温度的升高而逐渐增大；荧光随温度的升高逐渐减弱直至消失；有机差热研究表明，菌孢的成烃性能由强变弱，有机质变质程度逐渐增高；解析Ｘ衍射图谱，求出芳香度ｆａ 值，定量反映出菌孢中的饱和结构与芳香结构的变化规律及其有机质成熟度。通过这几项测试分析，探讨菌孢在热演化过程中有机质演变与成烃作用的关系，认为菌孢中有机质的演化大致经历了３ 个阶段：从常温至３００℃为未成熟期；３００ ℃至４００℃为成熟期，烃类大量生成；而４００ ℃～５００ ℃这一阶段菌孢中有机质变质程度高，为过成熟期，产烃性能变差。
Through the laboratory thermal simulation test of Alternaria tenuis, the test of bacterial spore reflectivity, fluorescence, organic difference heat and X-ray diffraction were carried out. In the process of thermal evolution, the refolding rate of the spores increased gradually with the increase of temperature; the fluorescence decreased gradually with the increase of temperature until it disappeared; the study of organic difference showed that the hydrocarbon-forming ability of the spores was changed from strong to weak , The degree of organic matter deterioration gradually increased; analysis of X-ray diffraction pattern, calculated the value of the value of the aroma aroma, quantitatively reflect the spores of bacteria in the saturation structure and aromatic structure of the law of variation and maturity of organic matter. Based on these tests, the relationship between the evolution of organic matter and hydrocarbon generation during thermal evolution was discussed. The evolution of organic matter in the fungus spores underwent three stages: from room temperature to 300 ℃, immature stage, 300 ℃ To 400 ℃ for the mature stage, a large number of hydrocarbon generation; and 400 ℃ ~ 500 ℃ during this stage in the high degree of organic matter spoilage, over-mature, poor performance of hydrocarbons.
