To evaluate the bioactivity of the glass-ceramics,the specimens were soaked in the simulated body fluid. The results indicate that fluorapatite shows needle-like microstructure, which is similar to that in human bone and teeth. The formation of needle-like fluorapatite is related to the heat treatment procedure, which results in needle-like fluorapatite crystals by accelerating one-dimension growth along the c-axis through the screw dislocation growth mechanism. The mechanical properties of the glass-ceramics are close to those of the human bone and teeth. The bioactivity test results show that apatite layer is precipitated on the materials surface after 3 d immersion in SBF, which indicates the glass-ceramics have a good bioactivity.
研究结果表明：氟磷灰石相呈针状，与人体骨和牙齿的磷灰石形貌相似，有利于提高材料的生物活性和生物相容性；氟磷灰石的形成是材料被迅速加热至高温进行热处理，使磷灰石以螺旋位错生长机制沿c轴晶化长大所致；经热处理获得的材料具有优良的力学性能，基本满足骨科和齿科用生物材料的性能要求；材料在体外模拟体液中浸泡3 d后，样品表面已有磷灰石层生成，表明该材料具有较高的生物活性。

The upper layer, with homogeneous composition, is mainly composed of intact phosphatic foraminifer fossils and nannofossils as well as abiotic carbonate fluorapatites, representing the biologic and autogenic origin. However, the lower layer, with visible metasomatic texture and relatively high Si, Al, K and Fe, is notably different from the upper one, and seems to have been formed mainly by replacement of carbonates.

In this study, EPMA and LA-ICP-MS were used to determine the major and trace element concentrations, respectively, of apatites from Transhimalayan granitoids. The results indicate that F, Mn, Sr and REEs in apatites generally show good correlations with compositions of their host magmas and thus have high potential to be utilized as petrogenetic tracers. More specifically, F and Mn contents in apatites are covariant with the aluminosity of the host rocks so that can be used as an indicator for magma differentiation. Combining with Sr and REE data, which show significant variations in apatites from different rock types, these elements may be furthermore used to construct "discrimination diagrams" for more detailed investigations of complex petrogenetic processes such as magma mixing and compositional heterogeneity.
本研究中，电子微探以及雷射烧蚀感应耦合电浆质谱术分别被用以量测藏南火成岩中磷灰石的主量与微量元素含量，微区分析的结果显示，磷灰石的氟、锰、锶以及稀土元素均与岩浆源成分展现良好的对比关系，揭示了它们应用在岩石成因示踪上的优秀潜力：其中，磷灰石氟、锰含量的变化与原岩的铝饱和情形息息相关，因此可以作为岩浆分异程度的指标；而锶以及稀土元素则在不同岩石类型来源的磷灰石中展现了明显的丰度变化，因此综合这些元素将有机会进一步建立岩浆来源的「鉴别图」，甚而以此讨论岩石成因，例如：岩浆混合与源区组成的不均一性。

Studies show that the average ratio of w/w(P2O5)(1.62) of phosphates in submarine guyots is the same as that of w/w(P2O5)（1.621）of carbonate-fluorapatite, but is obviously different from that of w/w(P2O5)（1.318）of fluorine_carbonate, suggesting that the phosphates from northwestern Pacific are species of carbonate_fluorapatite.Three types of microneedle-microcolumnar, microgranular and microcryptocrystalline carbonate_fluorapatite with different abundances have been found.
