Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.

低位泥炭沼泽由于潜水位较高，水流对泥炭沼泽表面的改造和冲刷作用较强，形成的煤层具有较高的凝胶化指数和地下水流动指数，并且与精煤产率呈负相关，煤中粘土矿物和黄铁矿难以洗选；高位泥炭沼泽形成的煤层具有较低的凝胶化指数和地下水流动指数，泥炭积累速度较快，其精煤的产率较高。

本文对蜡质玉米淀粉的糊性质、流变特性和凝胶强度等凝胶化性质进行了详细研究。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。
