The tooth depends on constantly using lately sharp blade noodles crystal to substitute the part that the bluntness drops to every moment keep sharp status

The structure analyzes
The uncle of Ji Er begins from 5 year agos to the research of sea urchin tooth especially.The original intention comes from one very simple, the question of kid is type:The tooth of sea urchin why always so sharp?
For this he takes a tour around the world and looks for the most advanced microscope and other scientific instruments to carry on an observation research to the structure of the sea urchin tooth.The research team is used a showing minute details of the most complicated nicety equipments observation sea urchin at past 6 months in the world complicated tooth structure.
The calcite crystal of two kinds of different forms sea urchin tooth shows microstructural to suggest, layer the main part that constituted a tooth, the 2 F is mutually wrong to cross to distribute, is connected with each other by a kind of stronger and tough calcite gum knot thing.The tooth depends on constantly using lately sharp blade noodles crystal to substitute the part that the bluntness drops to every moment keep sharp status.The key that attains this purpose, is spread Zhui opposite softer organic material layer is in the tooth.
