Introduction Since Ge isotope is a new nontraditional isotope,the accumulated Ge isotope literatures are quitelimited.The available researches mainly focused on two aspects:(1) the measurement of Ge isotopiccompositions of geological and extraterrestrial materials,such as igneous rocks,marine sediments,seafloor hydrothermal fluids,hydrothermal Fe-oxyhydroxides,terrestrial high-temperature geothermalfluids,sphalerite,and iron meteorites;and (2) theoretical prediction of germanium isotope fractionation.Here we report two cases on the analysis,fractionation mechanisms and geochemical tracing of Ge isotopeof Ge-rich coal and Pb-Zn sulfides from Southwest China.

The long-term issue of entropy production in transport phenomena is solvedby separating the symmetry of the non-equilibrium density matrix ρ(t)inthe von Neumann equation,as ρ(t)=ρs(t)+ρa(t) with the s
We explore the properties of the low-temperature phase of the O($n$) loop model in two dimensions.The stability of this phase with respect to several kinds of perturbations,including cubic anisotropy,
Negative differential resistance in electronic conduction has been extensively studied,but it is not the case for its thermal counterpart,namely,negative differential thermal resistance (NDTR).In this
