The basic types of vitrinite in humic coal;

The authors have done some thermal simulating experiments(at 800℃) on fifteen humic coal samples with different maturity and measured the content of hydrogen,carbon and oxygen elements.

Luacustrine mudstone and sapropel coal in the middle Permian and the low Jurassic as well as cannel boghead in the middle and upper Triassic have abundant exinoid group and saprepel group, they have highest hydrocarbon-generating potentiality in the basin, while humic coal distributed in the middle and lower Jurassic has abundant vitrinite and inertrinite which has poor liquid hydrocarbon genera.

Progress on the interaction of humic substances with uranium and TRU elements;

Applying Fe(Ⅱ), Mn(Ⅱ) and Cu(Ⅱ) ions for catalytic ozonation of humic substance(HS) in landfill leachate were studied.

The amount of nitrogin,humic substance,humic acid,and fulvic acid in the soils increases with increasing biomass,also following the above mentioned order.

Dynamic of humic substance complexed copper and its relationship with copper leaching during manure composting;

Property changes of humic substances from organic materials in different decomposing period;

The predominant organic matter in hydrothermal ore-forming fluid varies with temperature from humic substance (t < 50℃), carboxylic acids (t = 80 ~ 140℃), crude oil (t = 120 ~ 180℃), to water-soluble mehane (t = 180 ~300℃).
