拋物面雙曲面鏡At last, the surface of the alumina femoral head was grade - polished with sic micropowder and diamond grinding cream, the join part was trimmed with specific instrument, which made the surface of the alumina femoral head reach the degree of approximating mirror finish and match the femoral stem well. the artificial partial hip joint prostheses was finally got by articulating the alumina femoral head with ti alloy femoral stem coated with bioactive coating
最後,採用sic超細粉和金剛石研磨膏對氧化鋁陶瓷股骨頭表面進行分級拋光,用專用器械修整其聯接部位,得到表面具有近似鏡面光潔度並與股骨柄配合良好的氧化鋁陶瓷股骨頭,並與表面塗覆生物活性塗層的鈦合金股骨柄配伍,最終獲得人工半髖關節假體。Off - axis parabolic mirror
離軸拋物面反射鏡The design of amorphous photonic material and photonic crystal devicements we design to make a reflecting mirror of cylinder paraboloid of an antenna by using amorphous photonic materials. we calculated the transmission of the mirror and the distribution of electric field by using multiple scattering method. the result shows that it can be used as a reflecting mirror of an antenna
