Objective To explore the anatomic characteristics of the bronchi,arteries,and veins of pulmonary segments on the coronal section.

目的研究肺段和亚肺段支气管、肺动脉和肺静脉在冠状断面上的配布规律。

Methods 5, 3.75, 2.5 and 1.25 mm multilayer CT thin-section continuous reconstruction was used to compare the results of the segmental and sub-segmental bronchia in 38 cases of normal subjects.

对38例正常人分别采用5、3.75、2.5和1.25mm的MDCT连续薄层重建，比较其对肺段、肺亚段支气管的显示效果。

Consequently, left lung has nine bronchopulmonary segments, right lung has twelve bronchopulmonary segments.

因此 ，左肺有 9个支气管肺段，右肺有 1 2个支气管肺段。

The welding conditions can be conformed by the stress situation,6 different parameters were used for all position welding. The activating fluxes were deposed on the metal surface by a brusher.

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。
