The spectrum peaks nearby 530nm and 480 nm are corresponding with BTSD and BMD respectively. It is found from measurement that the luminescence peak from BMD is bluely shifted. The atoms of BTSD nearby dislocation core are affected by tensile stress along the Burger's vector direction leading to its band gap narrowed. In addition, there is the effect of part quantity of edge dislocation in BMD existed. Part of atoms in BMD are strained by compressive stress leading to its band gap narrowed, in other words, the wavelength from BMD is shorter than that from BTSD.

从测试结果中还发现BMD 的发光位较BTSD有所蓝移，分析认为BTSD位错芯附近原子沿伯格斯矢量方向只受到拉应力，致使禁带宽度变窄，BMD由于除了具有螺型位错的分量外还具有部分刃型位错的分量，而刃型位错中有部分原子受到压应力的作用，导致禁带宽度增宽，从而使得BMD的发光波长比BTSD短

［Objective］To explore the effect of continuous physiological osteogenic stress on the bone healing of canine iliopectineal crest.［Method］Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5 cm above the dome of acetabulum,which were fixed with ATMFS or steel plate respectively. The animals were sacrificed and specimens were procured at 2,4,6,8 and 12 weeks after operation.Samples from the fracture gaps were investigated by histology of HE and Masson staining,image pattern analysis of new bone formation.

探讨持续顺应生理力线的压应力对犬骨盆弓状线部骨折愈合的影响［方法］选用10只成年杂家犬，双侧髋臼臼顶上方1.5 cm处横形截骨，分别采用ATMFS(骨盆髋臼三维记忆内固定系统)柱固定器和5孔重建钢板内固定，于术后2、4、6、8、12周处死动物取材，行HE染色、Masson三色法染色组织学检查，图像分析新骨形成积分光密度值，研究不同应力作用模式下的骨盆骨折愈合情况。
