磷灰石

Results: 1. A collarless press fit canine femoral stem of CFRPSF composite (elastic modulus was 40 GPa, containing carbon fiber 30%) using HA (50%) and PSF (50%) composite for surface coating was made. Directions of carbon fiber in the stem were similar to the arrangement of trabeculae of proximal femur.

实验结果：1。用弹性模量为40GPa，碳纤维含量为30％的聚砜复合材料，制造出纤维排列方向模拟股骨上段骨小梁走行，表面涂层为羟基磷灰石50％/聚砜50％混合物的压配型狗人工髋关节股骨柄假体。2。

Almost all of this inorganic substance is a compound called hydroxyapatite.

几乎所有的无机成分都以一种被称为羟磷灰石的方式存在。

BACKGROUND: Hydroxyapatite has favorable biocompatibility, can protect pulp tissue and promote the formation of osteoid dentin and the concrescence of pulp tissue.

背景：羟基磷灰石具有良好的生物相容性，可保护牙髓组织，促进骨样牙本质的形成和牙髓组织的愈合，但无抗感染能力。

Objective: To discuss the filling effects of coralline hydroxyapatite in curettage of jaw cysts.

METHODS: Human PDLC cultured in vitro were collected and seeded on three-dimensional framework of coral and coralline hydroxyapatite.

组织块法培养人PDLC ，传代扩增后，接种于珊瑚和珊瑚转化羟基磷灰石两种三维支架上，体外继续培养 3d ，进行细胞计数和扫描电镜观察。

Coralline Hydroxyapatite used in curettement of jaw cyst could increase success rate and accelerate new bone formation.

在颌骨囊肿刮除术后植入珊瑚羟基磷灰石可引导成骨，有助于提高治疗成功率。

OBJECTIVE: To observe the osteogenic property of platelet-rich plasma induced human BMSCs in vivo and to explore the feasibility of ectopic osteogenesis of platelet-rich plasma induced human BMSCs and combined coralline hydroxyapatite.

目的：观察富血小板血浆诱导培养人骨髓基质干细胞在体内的成骨特性，探讨采用富血小板血浆诱导培养的人骨髓基质干细胞与珊瑚羟基磷灰石材料体内异位成骨的可行性。

Objective To estimate whether the implanted coralline hydroxyapatite prepared by hydrothermal conversion of coral can reach the level of compressive strength of bone in vivo, because CHA could be implanted in human body directly and then make the bone tissues grow into their porous structure, which will reinforce their strength.

目的 分析判定以珊瑚为基体，通过水热交换法制成的羟基磷灰石植入体内后的强度是否可以达到活体骨的水平。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
