Lithologic oil reservoir of the conglomerate fan-body developed in deep sag stage is the important target of oil-gas exploration in the mid-later term exploration in petroliferous basin, and it's oil-bearing potential is mainly dependent on the hydrocarbon expelling intensity of effective source rocks, the reservoir condition of gravel-sand fan-body and the result of their inter-action.

We have used the method of the hydrocarbon generation rate of organic carbon to separately calculate the hydrocarbon-generating intensity of coals and dark mudstones.

Decomposition analysis of CO_2 emission intensity caused by electric power consumption in China

This article puts emphasis on the analysis of the current situation of air pollutants,such as SO2 and so on,and the reason for the change of their emission intensity index on the basis of the research of air pollutant emission situation in Beijing from 2000 to 2004.

Results show that SO_2 and NO_X emissions in 1990 are 17518kt and 8422kt respectively and the heigh emission intensity areas are concentrated in middle East China.

Compared to the south side,the piezometric head have slower change,drained strength is smaller,and water-holding capacity is bigger in the soil of the north side as the compacted soil.
