To investigate the the body shape strength and kinematics that effects sprint expert performance 17 healthy male sprinters were measured using songxiam9000 high speed vidicon in the field ; body shape of sprint athlete were tested by steel rule ; meanwhile shoulder were tested at 60, 240and360 deg / sec velocities ; lower limb were tested at 60, 240 deg / sec velocitues using biodex - ii tesing and rehabilitation system in the laboratory this research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theory the result show that ( 1 ) the results of correlation indicate that 100m performance related to the shoulder fast flexion torque and hip flexion / extension torque ^ ankle fast dorsiflexion torque ; ( 2 ) the upper arm relaxing enclose and lower limbs length effect 100m performance ; ( 3 ) the biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100m performance
受試者為17名男子一、二級短跑運動員。使用
松下m9000高速攝像機對100米跑動過程中的運動員進行錄像,同時測試短跑運動員100米成績,利用愛捷錄像分析系統獲取運動學參數;用人體測量尺測試短跑運動員的肢體圍度;同時採用biodex -型等動測力及康復統,測試運動員上肢肩關節及下肢髖、膝、踝3個關節的等速
屈伸肌力。在角速度60 s (慢速) 、 240 s (中速)和360 s (快速)下測試肩關節等動向心收縮肌力;在角速度60 s9慢速)和240 s (快速)及120 s下測試下肢3關節等速向心及離心肌收縮肌力。

With the different loading ratio of parallel to axis and normal to axis direction, damage defects will occur bulking problem. by varying the degree of material anisotropy relative to the loading axis such as poisson ' s ratio and shear modulus, crack growth bulking strain value parallel to or normal to the loading axis is different. the parameters controlling the growth or arrest of the delamination damage are identified as the geometry and the depth of defects and radius of cylindrical etc. at last, it was investigated that the delamination damage is often induced by the tip of matrix damage under higher stress
研究結果表明:殼體筒段受軸向拉伸和內壓載荷作用時,軸向和環向載荷的比率不同,母層和子層可能發生拉伸
屈曲,也可能發生收縮
屈曲,或者同時發生拉伸和壓縮
屈曲;母層與子層各向異性存在差異,即泊
松比與剪切模量不匹配時,將使子層板的邊界上承受壓縮和剪切作用,當分層達到臨界狀態則發生
屈曲,當母層與子層的各向異性差異越大,則發生分層
屈曲的可能性越大;分層損傷的
屈曲應變值與子層自身的彈性模量、分層子層的形狀、厚度以及圓柱半徑等因素有關。
Through the strong pulling tests of four kinds of synthetic fiber filter cloth, the mechanical performance index of the filter cloth in dry and wet conditions were measured, the influence of various pulling speeds on the fracture strength and the fracture tensile rate of the filter cloth was derived. it was concluded that the stress of the filter cloth could relax when it was beyond the yield point
通過4種合成纖維濾布的強力拉伸試驗,測得了濾布在干、濕兩種狀態下的力學性能指標,得出了不同拉伸速度對濾布斷裂強度和斷裂伸長率的影響,同時指出當濾布的應力超過
屈服點時,會出現應力
