In this thesis,based on the DFT+NEGF first-principles method,we construct a lead-molecule-lead sandwich system with single benzene-based molecule to investigate the relationship between the structure and properties of the molecular devices and the factors that influence properties of the molecular devices.Our computational investigations on these molecular devices are primarily concentrated on the effect of contact geometry between molecules and electrodes,the effect of side groups,the effect of different torsion angle between two phenyl rings and the effect of external electric field.This thesis consists of five chapters:In Chapter one,we mainly introduce the research background and development of the molecular electronics,including the experimental fabrication of molecular electronic components and theoretical simulation methods.Afterwards we discuss the questions that need to be solved in this area.Finally,the main contents of this thesis are listed.In Chapter two,we introduce the theoretical methods used in this thesis, including the main first-principles calculation methods,i.e.,the Density-Functionmethod and nonequilibrium Green\'s function.

Conclusion］1? It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation? After using CFR/PSF of lower elastic modulus as handle, the stress dodge rate is lower in femur, but the interface stress is higher, and this is the main factor and reason for the prosthesis loosening? 2? The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal? The stress value in different combination of same prosthesis handle has no significant difference, that showes mechanical factor is not the main standard for selecting prosthesis combination?

［结论］ 1、各种假体植入后均在股骨距处形成较高的应力遮挡，而用弹性模量较低的CFR/PSF作为柄，其股骨相应区域的应力遮挡率较低，但股骨相应界面应力较大，而界面应力过大是产生假体微动主要因素。2、股骨界面从近端至远端呈逐渐增高趋势的应力规律符合该假体的设计原理；相同假体柄的不同组合其股骨和髋臼相应界面应力值无明显差别，实验表明力学因素并不是选择假体组合的主要标准。

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。
