查询词典 hexagonal prism

Based on the observation of atomic force microscopy, the etching morphology of faces and sections with different crystallographic significance on α-quartz has been studied. The etching morphology on the natural crystal faces hexagonal prism faces (1010 and 01(average10, rhombohedron positive form face 10(average11, rhombohedron negative form face 01(average11 and the sections between any of the two crystal faces has been observed.
