角频率

Driving experiments were conducted to investigate drivers' eye movements at the expressway tunnels. With a consideration of the average fixation time, the fixation proportion, the fixation duration, the fixation frequency and the visual lobe, a new eye movement index based on plane distribution of viewpoint was proposed to evaluate the driver's visual information processing level.

以高速公路隧道路段驾驶员视点变动为研究对象，在传统的平均注视时间动视点指标、注视时间比率动视点指标基础上，根据大量动视点行车实验，考虑驾驶员注视时间、注视频率、视力角等眼动特征，提出了基于视点平面分布的动视点指标，以评价驾驶员视觉信息加工水平。

It handles distance, area, angle, point, line, pixel profile and histogram, with statistics and frequencies.

操纵距离，地区，角，点，线，像素数据图表和柱状图，跟统计数字和频率一起。

The time and temperature dependence of dynamic modulus and phase angle of hot mix asphalt is analyzed,the master curve of dynamic modulus and phase angle is built using time-temperature superposition principle,the Witczak predictive equation is verified using the test results,which is helpful to provide good reference for China to use dynamic modulus as pavement design parameters.

分析了沥青混合料动态模量和相位角对温度和加载频率的依赖性，利用时间-温度置换原理建立了动态模量的通用曲线，并用动态模量实测结果对Witczak预估模型进行了验证和分析，为将动态模量作为沥青路面设计参数和混合料性能评价指标提供了有益参考。

The analysis of 3D noise indicates that the measurement is effective. Two MRC models of ICCD imaging system has been established based on system performance of energy and modulation transfer whose target is three-bar. One MRC model is under the condition of standard A lamp, and the other is under the condition of night photo-spectrum. Because the MRC models integrate sensitivity, noise, target spatial frequency, MTF and the performance of human eye all together, the MRC models can evaluate limit performance of photoelectric imaging system more roundly.

在系统能量传递特性和调制传递特性的基础上，以三条带图案为研究对象，从信号转换的角度出发，围绕每景象立体弧度角中ICCD的电子通量，建立了基于量子噪声和CCD噪声特性的微光ICCD成像系统MRC模型，MRC模型综合了系统灵敏度和噪声、目标空间频率、系统调制传递特性以及人眼视觉特性等因素，能更全面地反映光电成像系统的极限性能。

In this paper, we discuss a new cumulants-based method for the joint estimations of frequencies and 2D-DOAs of spatial signals.

提出了一种基于高阶累积量的信号频率和二维角估计算法。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
