石化鈣積層
英文
petrocalcic horizon-
They may also have a pertocalcic horizon, a fragipan or a duripan
也可能有一層石化鈣積層，脆磐或硬磐。2s ( th / u4u and 227th / 2x " th dating on two mammal fossil teeth gave age ranging from 85 to 139 ka, which evidence the stratigraphic order between the capping flowstone and the underlying fossil - bearing deposits and support to the age assignment of older than ca. aoo ka to die hominid fossil teeth
伴生的貘牙化石和鹿牙化石的二種鈾系法年代范圍為85 - 139ka ，表明該地點含化石堆積與表層鈣板間無地層倒序現象，支持人牙化石大於100ka的結論。We have carried out th / u dating on intercalated calcite samples. the results show that the capping flowstone layer is of an age of 94 ka, and the second one 220 ka. the fossil - bearing deposits which are bracketed by the two flowstone layers should be of an age between 94 and 220 ka
新生碳酸鹽巖與骨化石的鈾系測年結果表明：該地點覆蓋含人牙化石堆積的表層鈣板在約94ka以前開始形成，堆積疊壓的鈣板年代為約220ka ，人牙化石的年代應介於兩者之間。In this paper, rutilt oxide film, anatase oxide film on titanium, titanium surfaces containing calcium and containing phosphorus, and apatite coating - ti were surface characterized. based on investigation on apatite precipitation, protein adsorption and osteoblast culture in vitro on the titanium surfaces, the relationship between the bioactivity and the surface characterization of titanium was studied
在本論文中，通過金紅石二氧化鈦膜、銳鈦礦二氧化鈦膜、含鈣的鈦表面、含磷的鈦表面和ti -羥基磷灰石塗層的表徵，結合羥基磷灰石沉積、蛋白質吸附和細胞體外培養，研究了鈦的表面表徵與生物活性的關系。分享友人
