This rare species has some specifics in quality: both the content of konjac glucomanna and the molecular weight are higher, and the viscosity is relatively much better than the known species.

In this article,the analysis of rare gas using DID gas chromatography is introduced.

~(40)Ar/~(39)Ar dating for the Jiajika pegmatite-type rare metal deposit in western Sichuan and its significance;

This paper introduces the usage of important rare metal and the resources and development situation of the rare mental in China,and advances some concrete measures for protecting the important strategic materials and mineral resources.

China is rich in rare metal and rare earth element resource, current situation for some rare metal is still not ideal.

D-tagatose is a kind of rare sugar and mass production of D-tagatose is often developed using chemical or biological transformation.

D-tagatose 3-epimerase (DTE) family proteins were important enzymes during the processes of rare sugar bioproduction.
