序列信号 meaning in English
sequence signal
Examples
- Therefore , research on improving the image resolution of sar and isar continuously has been a hot as well important topic . time series echo signal can be decomposed to imfs ( intrinsic mode function ) by emd ( empirical mode decomposition ) algorithm , which is distributed following frequency
经验模态分解( emd : empiricalmodedecomposition )方法能够把时间序列信号分解成有限数目的本征模态函数( imf : instrinsicmodefunction ) ,分解结果按频率高低分布。 - The exo - atmospheric combat enviroment is introduced , including the outer - space ’ s optical signature , the optical and dynamic signature of the potential targets . the research focus is the precessing rv and tumbling decoy ’ s irradiance intensity ’ s periodical changing rule . a double periodical function model is presented to simulate their irradiance functions
根据空间弹道目标的光学与运动学特性,重点研究了进动旋转的弹头和翻滚运动的诱饵的光学强度序列信号的周期性变化规律,并采用双周期性函数来表示该光学强度信号,以反映弹头和诱饵在运动特性和表面辐射特征方面的差异。 - Artificial periodic disturbances are introduced to the outer field of turbulent boundary layer in an closed - circuit open water channel . statistical method is employed for analyzing the velocity - fluctuation - time - series . the effect of the disturbance to turbulent structure in boundary layer is studied
在开口式循环水槽底部湍流边界层外区中引入周期性扰动，对湍流场的速度脉动时间序列信号进行了统计分析，研究了湍流边界层中周期性人工扰动对湍流结构的影响，结果表明高频扰动的湍流中she - leveque简称sl湍流层次相似律成立。 - Semg signal is the sum of bioelectrical activities that recorded from the skin of working muscle by surface electrodes . the change in semg signal could reflect motor units activation patters and the status of muscle fatigue in some certain degree . because it was non - invasive and local sensitive , the technique of semg signal analysis had become very important method in examining and evaluating human muscle function
Semg信号是从肌肉表面引导和记录到的肌肉活动时神经肌肉系统生物电变化的一维时间序列信号，由于其检测具有非损伤性和良好的局部性以及semg信号的变化在一定的程度上能够反映运动单位的活动模式和肌肉疲劳的状态，因此应用semg信号分析技术检测和评价肌肉疲劳以及进一步探讨其生理机制具有重要的理论意义和实用价值。
