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 prepared PU was an elastic solid,which could dissolved in ethanol,and it exhibited strong deep purple fluorescence at the peak of 365 nm along with a shoulder at 386 nm as a thin film. Obviously,the prepared PU also was a kind of uncommon ultraviolet-emitting polymer materials.2.A novel water-soluble rod-coil block copolymer was designed and prepared successfully via the facile isocyanic acid polycondensation method using polyfluorene as rod segment and polyethylene glycol as coil segment in the main chain for the first time.

The result shows that for both PCL homopolymers and PCL-b-PEG block copolymers, the spherulitic linear growth rate first increases with molecular weight and reaches a maximum, then decreases as molecular weight increases. Crystallization temperature has greater influence on the spherulitic growth rate of polymers with higher molecular weight.
当自由PEG在水中的占有面积S_o与单根PEG链段所占有的表面积S的比值S_o/S的值接近或小于3时,PEG链段对胶束形状的影响较小,PCL嵌段的影响占主导地位,易形成片状胶束;当S_o/S的值在3-10之间时,随着PCL嵌段分子量的增加,PCL-b-PEG嵌段共聚物在水溶液中自组装形成类似球状、棒状和蠕虫状胶束,是PEG与PCL嵌段共同的作用的结果;当S_o/S的值大于10时,易形成球状胶束。

Water inside vacuum heat- collection tubes; since the hot medium inside vacuum tubes floats up and cold one goes down due to respective specific gravity, hot and cold mediums convections up and down to cause the heat conduction, furthermore transfer the heat to the related working medium in the heat tubes, the working medium sorbs the potential heat and becomes steam to rise up to the condensing section from the tube heat evaporating section; it emits the heat in condensing section to change again into liquid working medium; it flows back to evaporating section under the gravity action, the emitted heat is transferred into the water inside water tank or tube group by means of the heat-conduction through heat tubes condensing section; it makes the cold water in water tank into hot water in the repeated way.
阳光透过全玻璃真空集热管的外玻璃,照射到涂覆在内玻璃管外表面的选择性吸收涂层上,涂层将太阳的辐射能吸收并转化为热能,通过内玻璃管壁导热,传递给真空集热管内其液态传热介质,由于真空集热管内热的介质因比重小而上浮,冷的介质因比重大而下沉,冷热介质上下对流传热和导热,再通过热管的金属壁导热,将热量传递给热管内其相变工质,工质吸收汽化潜热而变成蒸汽,由热管蒸发段上升到冷凝段,在冷凝段放热冷凝,又变成液态工质,在重力作用下流回蒸发段,所放出的热量通过热管冷凝段金属管壁导热,传递给水箱或联集管内的冷水,周而复始,于是便将水箱内的冷水全部加热成热水。
