查询词典 compressive

The results show that: the input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar; the stress distribution of the femur under external violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.

分析结果表明：股骨颈处的压力骨小梁和股骨距是重要的承载结构，临床医学治疗股骨颈骨折时，内固定物的放置应循压力骨小梁方向并尽量紧贴股骨距钻入；暴力作用时股骨上端的应力分布特点从生物力学的角度说明了老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

The external fixator was a good, economical, effective and simple method in the treatment of femoral neck fracture. The three pins used in fixation of femoral neck fracture are important. The placement of the pins should be in accordance with the compressive trabeculae and clingy to the femoral calcar.

3动力髋螺钉虽然在固定强度上优于其它各组，但却由于手术创伤大、对股骨头残存血供破坏较大等缺点而限制了其应用；自行设计的外固定支架为一种简单、有效、实用、经济的固定方法，有一定的推广价值；穿针方向应循压力骨小梁方向尽量贴近股骨距低角度倒三角形钻入才符合生物力学原理。

(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

On the fracture section, three strain gauges were put above the pins of groups fixed with external fixator. The gauges were recorded when the femurs were loaded vertically. Results (1) The compressive trabeculae and femoral calcar in the femoral neck region are the main load-bearing construction. The contract of the abductor muscle can protect the hip joint. When the model femur was abducted in small degree (10-30°), the stress improved gradually with the abductor angle. But adduction of the model will gradually decrease the stress in that area. When external violence was put on it, the main stress distribution was on the upper femur, which was in the middle and lower part of the femoral neck and between greater trochanter and lesser trochanter.

同时在④⑤两组又应用电阻应变片贴于断端间的三枚斯氏针上方以测定钢针上的应力与应变结果(1)股骨颈处的压力骨小梁和股骨距是重要的承载结构；载荷的传导主要通过压力骨小梁和股骨距由股骨颈区传至股骨干的中下1/3处；外展肌力的收缩对髋关节有一定的保护作用；在小角度外展实验中（10-30°）股骨颈区的应力递增，超过30°时股骨颈区的应力又逐渐减小，但在内收实验中随角度增大股骨颈处应力呈递减趋势；当外界暴力作用时，应力主要集中在股骨上段，即股骨颈中下段和大小转子处及其之间。

Objective To investigate the effect of different diameter powder on setting time and compressive stress of carbonated hydroxyapatite cement.

磷酸钙水泥作为一类新型的骨缺损修复材料，具有良好的生物相容性和原位固化性能，逐渐成为近年的研究热点[1，2 ] 。
