Results Both X ray and tissue slicing showed that woven, trabecular and laminar bones were formed throughout the whole defected areas during different stages of restoration in the experimental group while osteogenic tissue only appeared in the margin of ceramic in the control group. 结果无论X线摄片及组织切片均表明,实验组颅骨极量缺损修复优于同期对照组。
Since the endothelial adhesion, growth and function of seed cell are significantly modulated by laminar shearing stress, dynamic culture of cell is essential to tissue engineering vessel for meeting the physiological requirements. 考虑到流体切应力对种子细胞的影响,动态培养种子细胞可促进种植后细胞的粘附性、细胞生长及功能的发挥,使组织工程血管更符合生理需要。
Laminar cooling is one part of the technique for the control of rolling and cooling, it effects the tissue and properties of strip directly. So laminar cooling process plays an important role in hot strip production. 层流冷却作为控制轧制和控制冷却技术的一个组成部分,直接影响带钢的组织和性能,所以层流冷却过程成为热轧厂生产过程中非常重要的环节。
