vep造句

• Analysis of visual acuity with vep technology
  应用视觉诱发电位分析视力的价值
• Visual evoked potential , vep
  视觉诱发电位
• Vep visual evoked potential
  视觉诱发电位
• The visual evoked potential ( vep ) has a very important role in the field of neurological physiology and clinical diagnosis
  视觉诱发电位在神经生理学和临床疾病诊断等方面有极其重要的价值。
• Visual evoked potential ( vep ) is a gross electrical response of the brain time - locked to an external visual stimulus
  视觉诱发电位( vep )指由于外部视觉刺激而在视觉通路上产生的可以在头皮上测量到的电活动。
• Another advantage of anfis lies in that it can track the dynamic behavior of vep in a real - time fashion because the vep variation tracking is important for critical patient monitoring in the clinical situation
  本文探讨了anfs在提取视觉诱发响应( vep )信号中的应用，并结合临床实验提出了一种新的单次提取方法。
• In this article a visual stimulation system with a number of stimulating patterns for bci realized is described , and three stimulation patterns , for vep , p300 , and motor imagery on the computer screen realized is described by computer programming
  本研究基于多种刺激模式的脑机接口视觉刺激器，采用计算机编程，在计算机屏幕上实现了基于vep 、 p300 、想象运动的3类刺激模式。
• The ica technique separated successfully electromyographic ( emg ) and electro - oculographic ( eog ) artifacts from eeg data ; accomplished vep strengthening and extraction ; separated watermarking and key from mixing digital image signals , even though under strong noise , the results still have very good performance index
  独立分量分析技术可以很好地分离出eeg数据中的肌电与眼动等干扰；实现了vep的增强与提取；很好地分离数字图像信号中的水印与密钥，即使在很强的干扰情况下，仍具有很好的性能指标。
• However , nonlinear dynamic methods are rarely investigated in view of their complexity , and the fact that the nonlinear characteristics of the signal are hard to determine in general ~ an adaptive noise cancellation method with anfis was carefully designed to estimate the vep signal
  本文用anfis辨识可测噪声源与响应的不可测干涉之间的未知非线性模型，将线性自适应噪声消除的概念扩展到非线性领域。 anfis可以对非线性函数建模，可动态跟踪vep在每次试验中的变化。
• Ensemble averaging ( ea ) is a conventional method for improving the snr of the recorded vep . depending on the snr of the recorded signal , ea requires 100 - 2000 trials to estimate an ep . targets of others methods are concentrated on decreasing the number of repetitions required and speeding up ep estimation
  但是平均方法忽略了每次试验之间vep的变异，而且反复刺激会引起神经系统疲劳，危重病人难以承受，也将直接影响到诱发响应的波形，因此对vep进行单次或少次提取并跟踪每次试验中vep的变化成为人们关注的研究目标。
• This paper ' s contents include : brain science and analytical actuality of eeg signal , theory of ica , research headway of evoked potential ( ep ) extraction technique , classes and processing algorithms of digital image watermarking , and ica technology ' s application ( in eeg / vep and digital image watermarking processing ) , finally , summarized the work of this paper and some problems on the ica technique which to be solved were presented and the direction of the development pointed out
