目的评价组间肌电反复性对不同肌肉组选择导出模块的影响。方法记录12名参与实验者在自选速度下行走时16块肌肉的肌电图。用组内相关系数评价每个步行周期的肌肉兴奋度和肌肉模块。依据肌肉兴奋度的反复性,区分出3种类型的肌肉组。结果可靠肌肉组显示出较高的组内相关系数(>0.4),而全身肌肉组和混合肌肉组显示出较低的组内相关系数(<0.4)。3种类型肌肉组比较,可靠肌肉组分析得出的模块具有最好的反复性,全身肌肉组和混合肌肉组的反复性较低。结论具有较高可靠性的肌肉兴奋性能够得出较一致的模块。得出一致模块的方法非常重要,尤其是在依靠肌肉兴奋性反馈而改变的运动模式中。

Semiconductor microdisk lasers have great potential as low-threshold,high-speed,and small-form-factor light sources required for photonic integrated circuits because of their high-Q factors associated with long-lived whispering gallery modes(WGMs).Despite these advantages,the rotational symmetry of the disk shape restricts practical applications of the photonic devices because of their isotropic emission,which lacks directionality in far-field emission and difficulty in free-space out *** overcome this problem,deformation of the disk cavity has been mainly ***,the approach cannot avoid significant Q degradation owing to the broken rotational ***,we first report a deformed shape microcavity laser based on transformation optics,which exploits WGMs free from Q *** deformed cavity laser was realized by a spatially varying distribution of deep-sub-wavelength-scale(60 nm diameter)nanoholes in an InGaAsP-based multi-quantum-well *** lasing threshold of our laser is one-third of that of the same shaped homogeneous laser and quite similar to that of a homogeneous microdisk *** results mean that Q spoiling caused by the boundary shape deformation is recovered by spatially varying nanohole density distribution designed by transformation optics and effective medium approximation.
