The natural thermoluminescence profiles and cosmic ray exposure history of the Jilin meteorite;

Many foreign big companies carry on extensive reorganization and amalgamation too, the enormous change has taken place in the internal and external environment that Jilin petrochemical industrial corporation is in.

Comparison and Analysis of SO_2 Pollution and Sulplur Content of Trees Between Shenyang East Tomb Park and Aerolite Hill Park;

On TEM Method for Studying Ringwoodite with High-pressure Phase Minerals in Naturally Shocked Meteorites;

Chemical separation and purification of cosmogenic radionuclides ~(10)Be and ~(26)Al in meteorites;

Petrography and mineral chemistry of 100 meteorites collected from the Grove Mountains,Antarctica,were studied and their chemical-petrographic types were assigned.

On the basis of the distribution area, density as well as the diversity of the petrographic, mineralogic and chemical characteristics, we regard the Escarpment zone in the Grove Mountains as a new meteorites enrichment area.

Thermoluminescence studies of meteorites suggest that the level of natural TL in meteorites is determined by competition between build up,due to exposure to cosmic radiation,and thermal decay.
