| 摘 要： | 应用广义相关时间延迟估计方法，经由诱发电位潜伏期变化的测定，分析研究了撞击加速度和缺窒息实验条件下中枢时间系统的损伤问题。计算机模拟和诱发电位信号分析表明，当神经系统发生损伤时，诱发电位的潜伏期会出现显的变化，这种化可以由广义相关时间延迟估计方法而有效测定。

| Abstract: | The injury in the central nervous system under the impact acceleration and hypoxia experiments are detected and estimated by the generalized correlation time delay estimation algorithms, viathe latency change estimation of evoked potentials. It is shown by the computer simulation and dataanalysis that the latency change is a good indicator to the injury in the central nervous system and itcan be detected properly by the generlized correlation time delay estimation. |
