Taking the largest length of straight line section on which the running time is no more than seventy seconds as the control condition,the largest length of straight line section calculation model based on operation speed of freeway was presented.
从车辆运行状态的角度出发,将直线段上车辆的运行分为加速行驶、匀速行驶和减速行驶3个过程,分析了车辆在不同行驶过程中的行驶时间与行驶距离,以直线段上最长行驶时间70 s作为最大直线段长度的控制条件,推导了基于运行车速的高速公路直线段最大长度计算模型。
Purpose To explore the brainstem auditory function in preterm infants with perinatal hypoxia,maximum length sequence brainstem auditory evoked potential(MLS BAEP) was recorded to study whether different level of hypoxia would exert different effect on brainstem function and if MLS BAEP was better for early detection of brain damage than the conventional BAEP.
目的用最大长度序列(MLS)脑干听觉诱发电位技术检测有围产期缺氧早产儿生后早期的脑干功能,研究不同程度缺氧对脑干功能的影响,并比较MLS脑干听觉诱发电位是否较常规法对异常的检出具有优越性。
When the maximal length sequence correlation (MLC) technique is applied to the secondary path modeling for narrowband active noise control systems, the system performance is easily affected by narrowband signals.
本文针对最大长度序列相关(Maximal Length sequence Correlation,MLC)建模技术在窄带主动噪声控制系统次声学路径建模的应用中,系统性能易受窄带信号影响这一不足,提出了一种改进的MLC(MMLC)次声学路径建模技术。
