Studies of Phase Transition of Partly Metamict Fergusonite at High Temperature
《Chinese Science Bulletin》1993年第19期1626-1631,共6页杨学明 张培善 陶克捷 
Project supported by the National Natural Science Foundation of China
1 Introduction The mineral whose chemical formula is simply written as YNbO4 has naturally two polymorphs: fergusonite and fergusonite-β. The former is tetragonal and the latter is monoclinic. It is diffic...

A CRYSTALLOGRAPHIC STUDY ON THE DOMAIN STRUCTURE OF P2_1ca ORTHOPYROXENE
《Chinese Science Bulletin》1990年第18期1552-1554,共3页徐洪武 徐惠芳 
Recently, a breakthrough has been made on the topological structure of orthopyroxene. The result shows that the space groups of all natural orthopyroxenes are P21ca, instead of the conventionally held Pbca....
