This study analyzes the function of different muscles during arm wrestling and proposes a method to analyze the optimal forearm angle for professional arm wrestlers.We built a professional arm-wrestling platform to measure the shape and deformation of the skin at the biceps brachii of a volunteer in vivo during arm wrestling.We observed the banding phenomenon of arm skin strain during muscle contrac-tion and developed a model to evaluate the moment provided by the biceps brachii.According to this model,the strain field of the area of interest on the skin was measured,and the forearm angles most favorable and unfavorable to the work of the biceps brachii were analyzed.This study demonstrates the considerable potential of applying DIC and its extension method to the in vivo measurement of human skin and facilitates the use of the in vivo measurement of skin deformation in various sports in the fu-ture.

随着煤矿开采深度的加大,侏罗纪煤层向石炭纪煤层倾斜,运输巷道和回风巷道也在逐渐的变长,保证回采设备的的安全稳装,切眼工作面的开口、贯通、二次开口扩帮的巷道支护设计显得尤为重要.对燕子山矿C3煤层8212工作面开切眼巷道支护设计进行研究,考虑在遇到断层、上覆采空区及过25 m的煤柱压力区时,出现钢带断裂的情况,对专用锚杆轴力动态监测,通过ABAQUS数值模拟软件对切眼工作面在第1次掘进贯通时无支护条件下和有支护条件下的围岩应力、应变分析,之后在进行切眼工作面在第2次扩帮时以相同的方法进行分析比较.通过现场实
针对回采工作面单体支柱超前支护存在支护强度不足、工人劳动强度大等问题,提出了采用超前锚索主动支护替代原有的单体支柱被动支护的技术方案,并针对协庄煤矿三心拱巷道建立了围岩变形预计模型,通过理论分析得到了巷道合理超前支承力为0.83 MN,而超前锚索支承力可达到1.52 MN,满足超前支护需要;确定了巷道超前支护技术参数为:顶板每排布置3根φ22.0 mm×8300 mm超前锚索,排距1000 mm;在协庄煤矿11101工作面回风巷进行了应用,并在工作面推进过程中检测了超前支护段的围岩松动圈、围岩变形及锚索受

推移质泥沙颗粒的跃移是河流泥沙运动的重要形式.为了研究推移质颗粒跃移运动参数的变化规律,在水槽试验中采用高速摄像技术,观测7种工况条件下,0.3～1.7 mm粒径的推移质颗粒的跃移运动形态,提取颗粒跃移运动的时空信息,分析了泥沙颗粒跃移距离和跃移高度的变化规律.结果 表明,相对跃移高度和相对跃移距离的概率密度分布函数均服从Γ分布,对比前人的试验结果发现,4组试验颗粒的相对跃移距离概率分布的峰值提前,而其他3组试验结果的峰值几乎同时出现.试验值与韩其为公式的计算值基本符合,验证了理论计算值的合理性和可靠性.
