ChuXueJi 初学记 and BaiKongLiuTie 白孔六帖 are two category books with special and characteristic edit, with very high—quality academic value and document value, keeping a great quantities precious cultural inheritance of ancient times.

A new method for processing the hexagonal hole in the axle by hot backward extrusion on the friction press was proposed,which threw away the traditional milling or slotting method.

TEM and SEM results showed that silica microspheres were monodispersed and hollow;SXRD showed that hexagonal mesopores are in silica microsphere shell;experiment results indicated that the size of silica microspheres can be adjusted by the size of template microspheres,and thickness of the silica shell can be changed by adjusting tetraethyl orthosilicate.

An accurate analytic method of a composite material plate with different hexagon holes is founded based on the conformal mapping of complex function theory.
