PTFE and NPG exhibit a poor biocompatibility, while β-TCP and CPC have a good biocompatibility, and CPC is the most biocompatible of all the biomaterials tested.

聚四氟乙烯和NPG的生物相容性程度较差，β-磷酸三钙和固化的磷酸钙骨水泥的相容性较好，尤其是固化的磷酸钙骨水泥。

The crystallite-covered samples were immersed in the supersaturated solution, and the crystallites grew to uniform calcium phosphate coatings.

再将磷酸钙晶体覆盖的Ti6Al4V浸入过饱和溶液后，表面的磷酸钙晶体迅速生长成为均匀的磷酸钙涂层。

Nano-zirconia particle diameter and calcium phosphate powder, added sufficient quantum compound SiO2 and Na2O adjunct, after added deionise water and grind 4h, select polyurethane scaffold (interval porosity of 75%、85% and 92%, pore diameter 300um) as mould to obtain nano-zirconia calcium phosphate scaffolds.

以纳米氧化锆颗粒和磷酸钙粉体为原料，加入适量含SiO2和Na2O的复合添加剂制成复合粉体，加入去离子水后混磨4小时，分别选用孔隙率75%、85%和92%，孔径为300um的聚氨酯支架为模板，制成纳米氧化锆/磷酸钙骨支架。

In previous studies, most of the results emphasized the role of microorganism-induced mineralization of calcium phosphate, a taphonomic process known as authigenic mineralization. In their results, the calcium phosphates only mineralized outside the cells but never found inside the cells.

从实验的结果来看，磷酸钙仅沈积於细胞膜外，但在化石纪录中我们甚至可以看到细胞核、叶绿体等构造被沈积的磷酸钙矿化保存下来。

Objective To investigate the biomechanical behavior of injectable recombinant human bone morphogenetic protein-2 (rhBMP-2)/calcium phosphate cement used in vertebroplasty in primate models. Methods Two fresh cadavers of adult rhesus were used as group Ⅰ, and 4 adult rhesuses were divided into groups Ⅱ and Ⅲ.

Two approaches were reported in experimental simulations of calcium phosphates mineralization of soft-bodied fossils.

磷酸钙沈积在细胞内部的机制有两种，旧有的文献中都倾向於微生物的作用所导致磷酸钙的沈积。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
