各温度下每个成分的特征离子峰积分面积相加，作为每个成分的形成总量；由于各**每个温度下各成分形成总量绝对值差异较大，因此以A的形成总量为1（归一化），进行相对比较。
integral area 积分面积 typical ion peaks特征离子峰
The integral area of typical ion peaks of each component was summed up as the formed total amount of each component and the total amount of A was taken as 1for relative comparison considering that the formed total absolute value of each component at each temperature varied greatly.
从图10中可以看出，B的生物碱以及含氮化合物如尼古丁、吡啶、3-乙烯基吡啶、丙烯腈等成分产量远高于A和C，这显然是因为B含氮化合物含量较高造成的；A中挥发性羰基化合物（醛、酮）、呋喃等裂解产物生成量远高于B和C，这应与A糖类含量较高有关；此部分实验结果与之前的研究报道相符，而烯烃类化合物以及苯系物则没有表现出明显的规律性差异。
As can be seen from Figure 10, the alkaloids and nitrogen-containing compound in B such as nicotine, pyridine, 3 - vinyl pyridine , acrylonitrile ,etc,is much higher than in A and C, which is apparently due to the higher content of nitrogen-containing compound in B . As far as A is concerned ,the crackate formation amount of volatile carbonyl compounds (aldehydes, ketones), furan ,etc,is much higher than in B and C, which should be related to the higher saccharides in A .This results consistent with previous reports. The olefin compounds and BTEX showed no obvious regularity differences.
