| 摘 要： | 研究表明，现代松粉热模拟实验释放水的产出分两个阶段，两类水，第一阶段，４００℃以前释放水为松粉内部以水分子形式存在的结合水，呈弱酸性（ｐＨ＝６），为第一类水，第二阶段，４００℃以上温度释放水为松粉内部和高岭石内部结构水（－ＯＨ），呈弱碱性（ｐＨ＝９），为第二类水，现代松粉热模拟实验产出气体量随温度升主呈逐渐上升趋势，４５０℃以后上升梯度突然增大，所产气体分为两大类：Ｉ类为无机气体，由Ｎ２、Ｈ２和ＣＯ２气体组成，以ＣＯ２相对丰度最主为特征。ＣＯ２气主要来自有机酸的脱羧反应和离子太氧与有机质氧化还原反应产出ＣＯ２。Ｈ２气主要来自孢粉和烃，Ｃ４～Ｃ６异构饱和烃及丙烯、丁烯不饱和烃等分子物标志物，其中以甲烷相对丰度最高为特征，气态有机烃来自孢粉内有机物的热降解产物，松粉 拟实验中丰富的气态有机烃和无机气体的检测出，为研

| Abstract: | The study results indicate that there are two stages and twokinds of water produced through thermal experiment of pinus pollen. The water produced below 400℃ belongs to first stage and is the first kind of water. Those water store in pinus pollen with water molecule tipe and show weak acid medium (pH= 6). The water produced higher than 400℃ belongs to the second stage and is the secoNd kind of water. Those water are stored in structure (－OH) of pinus pollen and kaolinites,and show weak alkaline medium (pH= 9). The produced gas quantity increaced gradually when temperature rising and the rising speed increased suddenly when temperature is higher than 450℃. There are two kinds gases produced from pinus pollen. The I kind is inorganic gas which is composed of CO2, N2 and H2, within the CO2 abound is the highest. CO2 came mainly from deearboxyluted reaction of organic acid. H2 came from dehydrogenated reaction of organic matter. N2 came from denitrogenated reaction of introgenous organic matter in pinus pollen. The Ⅱ kind is organic gas which is composed of nC1 -6, iC4～6, propene and butene, within the CH4 abundance is the highest. The organic gas came from the thermal degradation reaction of organic matter in pinus pollen. The results of Pinus pollen thermal experiment provide a useful information for investigating terrestrial nature gases. |
