Clinical Application of Sky Bone Expender System in the Treat-ment of Vertebral Compression Fracture 膨胀式椎体成形器治疗椎体压缩骨折的临床应用
This kind of multilayer structure could prevent the expender of cracks. 这种多层结构可抑制裂纹的扩展,提高膜层的抗断裂强度。
Design of Optical System for Φ_0300 Laser Beam Expender Φ0300激光扩束器光学系统设计
Using short resonator and the time expender with a resolution of 10 ps the effect of pumping energy, concentraction and flow speed of the dye on the mode-locked pulse-width is studied. 采用短谐振腔结构,利用分辨率10ps时间扩展器研究了染料浓度、流速与泵浦能量对锁模脉宽的影响。
At present, determination methods on the internal pressure in the expender capsule ( called as intracapsular pressure), which may be used in clinic, and the comparative studies on the expanded skins in different locations of the body were rarely reported. 目前,对于可用于临床的囊内压测定方法及不同部位被扩张皮肤之间的比较研究罕见报道。
