中文摘要：

与不同方法提取的腐殖的物质(HS ) 的结构特征和粘合剂性质主要到基本分析，可见光谱，英尺红外光谱学，粘性，吸附和 pelletizing 实验的术语被学习。结果显示出与新方法提取的那 HS (HS -- 一) 比 HS 的 aromatization 和聚合，更大的相对的分子的团和更多的极的功能的组的自己的更高的度与平常的方法(HS-b ) 提取了。HS-b 的粘性是大约 3040 mPafer 过程被建立。与模型一起，然后，火来源的可视化根据 MATLAB 模拟站台被认识到。结果显示出那：1 ) 当检测深度是不到 2 m 时，在 10 m 以内，矿石表面上的温度不安能很快，然后慢慢地变化；在 4 m 以后，相反，它几乎不变化，并且在 10 m 对零近平；2 ) 当它接近自我点火持续时间，侦探深度是 2， 5 和 10 m 时，分别地，最大的温度差别是 correspon？

英文摘要：

The structure characteristics and adhesive property of humic substance （HS） extracted with different methods were mainly studied by terms of elementary analysis, visible spectrum, FT-IR spectroscopy, viscosity, adsorption and pelletizing experiments. The results show that HSs extracted with new method （HS-a） own higher degree of aromatization and polymerization, larger relative molecular mass and more polar functional groups than HS extracted with usual method （HS-b）. The viscosity of HS-b is about 30- 40 mPa.s lower than that of HS-a. The maximum adsorption amounts of HS-a and HS-b onto iron concentrates are 9.11 mg/g and 8.08 mg/g, respectively. Meanwhile, HS-a has a better performance than HS-b in the practical application for pelletizing of iron concentrates. The difference in agglomeration behaviors with iron concentrates lies in the differences of the structure characteristics of HSs. With higher content of polar functional groups, larger relative molecular mass and viscosity of HSs, the agglomeration behavior is improved.
