In order to avoid these disadvantages,MES was analyzed by crosspower spectrum coefficient(CSC) method.
传统检测方法处理表面肌电信号(SMES)时,个体差异比较大,本文针对这一不足,应用互功率谱比值法对肌电信号进行处理,并分析互功率谱的各项参数和对应肢体动作变化之间的关系,消除了肌电信号实际测量中不可测噪声的干扰。
补充资料:X线滤线栅比值
X线滤线栅比值
放射学术语。又称栅比。系滤线铅条高度与其间隔距离的比值。栅比值影响滤线栅吸收散射线的效能,二者呈正比关系,而摄影条件的增幅也随之加大。栅比值的设置范围一般是4~16。实际应用中,栅比不宜过大,多为6∶1和8∶1。
