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。

The results were summarized as followings: the density of planktonic crustacea in middle reach was higher than that in the lower reach whereas the species abundance and community diversity index in the lower reach were higher than that in the middle reach; the planktonic crustacea communities presented high density but lower diversity in the upper part of the middle reach, lower density but high diversity in the lower part of the middle reach and estuary, and lower density and diversity in the lower reach except the estuary.

结果表明，汉江中下游江段浮游甲壳动物的密度分布呈现出中游高于下游的特征，而物种丰度和群落多样性指数则是下游高于中游；中游上段的属于密度高但多样性低的群落、中游下段和汉江口属于密度较低但多样性高的群落，下游除汉江口外属于密度和多样性均较低的群落。

Based on the sedimentary system types, the characteristics of the favorable reservoir of Silurian in Tahe area are analyzed. It is considered that the vertical distribution of reservoir is controlled by tectonic movement and eustatic sea level change. The vertical distribution of reservoir is predicted. The favorable reservoirs converge in lower and upper Kepingtage Fomation and Tata' ai' ertage Formation
