运用表面肌电与摄像同步测试技术,本文分析重剑复合步法腿部肌肉的用力特征,旨为运动训练和教学提供理论依据。结果:向前两步出弓步过程中,前腿所有肌肉和后腿股内外肌积分肌电出弓步时显著性大于前两步;弓箭还原后退两步过程中,前腿股内外肌、股二头肌积分肌电弓步还原显著性大于后退两步。结论:后腿腓肠肌是前两步启动和前移的主要用力肌肉;弓步的加速,主要是后腿股四头肌力量变大和前腿发力变大的协调配合;复合向后步法过程中前腿股内外肌是推动身体后移的主要用力肌肉。

由于长城本身具有重要的文化和历史价值,长城保护工作得到了国家及各级政府的普遍重视。从绩效棱柱模型的角度尝试对于地方政府保护长城绩效评价体系建设。从理论选择和适用性分析开始,以利益相关者满意、利益相关者贡献、组织战略、业务流程、业务能力五个维度构建了指标体系并赋以恰当权重。为了保障长城保护纳入绩效评估法律机制顺利实施,又从建立地方政府长城保护绩效的法律制度、建立长城危机预警机制、树立长城保护模范、引发示范效应四个方面给出了建议,以期为完善长城保护体制提供理论参考。

作者： Xin shang Hai-wen Liu Ke xia Department of Physics Beijing Normal UniversityBeijing 100875

We study the charge transport properties of the spin-selective Andreev reflection(SSAR)effect between a spin polarized scanning tunneling microscope(STM)tip and a Majorana zero mode(MZM).Considering both the MZM and the excited states,we calculate the conductance and the shot noise power of the noncollinear SSAR using scattering *** find that the excited states give rise to inside ***,we numerically calculate the shot noise power and the Fano factor of the SSAR *** calculation shows that the shot noise power and the Fano factor are related to the angle between the spin polarization direction of the STM tip and that of the MZM,which provide additional characteristics to detect the MZM via SSAR.
