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。

Mechanical environment, as a native survival one, is very complicated and constituted of many different kinds of forces, such as the forces in vitro or between tissues and cells, and the interactive intracellular stress during the process of formation and remodification of cytoskeletons. All these forces regulate bodies' developments and cellular differentiations, which is particularly obvious in bone tissues.

力学环境是自然赋予生命体的一种生存环境，在这个复杂的环境中，生物体外的力、生命运动过程中产生的体内各组织、细胞间的相互作用力及细胞骨架形成和变化时产生的细胞内张力交互作用，构成了一个力学系统，调节着生物体的生长发育和细胞分化，这一点表现在力对骨骼系统的作用上尤为明显。

由于生物高分子活性中心元素是生物营养体的组成成分与催化激活的主要内在原因，其摄入，积累，运送与分布都与生物体的生物功能密切相关，所以可以通过金日光教授提出的第四统计力学——群子统计理论来考察其分布规律，进而考察、评价食疗型生物体的生物功能，从而为研究生物体的营养、药物功能提供新的理论依据，为诠释中国传统食疗学的相关理论打开新的思路。
