The lead and sulfur isotope analysis suggests that the tremendous thick and stringer ore bodies may be formed by fluid of different geologic periods.

The new method of the thermal ionization mass spectrometry permits analysis of sulfur isotope with a precision for δ34S of 0.

Acid rain has been one of the most serious environment problems in the world and the study of sulfur isotope can help us find the sulfur source,composition and have important significance for research to harness acid rain.

The free carbon and hydrogen isotopes in n-alkane from the Paleozoic source rocks in Huanghua depression are determined using techniques of GC-IRMS and GC-TC-IRMS to reveal the isotope compositions in different sedimentary environments.

Palladium-hydrogen system has the largest isotope effect in the metal-(hydrogen) systems so far as we know,so palladium is widely used in hydrogen isotopes(disposal) technology.

In addition,the experiment working standard of H2 was certified by H2 /H2O(l) equlibrium H/D isotope analysis associating with hydrogen isotope fractionation equilibrium.
