Due to the high-dimensional mapping that neural network fits contains complex intrinsic attribute dependencies, the traditional optimization methods have not conducted the analytical study on it.

由于神经网络拟合的高维映射存在复杂的内在属性依赖关系，而传统的优化方法却没有对其进行分析研究。

Methods Static isometric loading of the biceps and low back muscle was performed in 14 subjects, using FFT power spectrum and its two dimensional mapping to analyze SEMG signals from these muscles.

方法14名受试者分别参加肱二头肌和腰部脊竖肌等长运动负荷实验，取表面肌电信号进行FF T功率谱及其功率谱二维地形图分析。
