The smallest characteristic value corresponds to the lowest natural angular frequency.
The Fourier transform can also be written in terms of angular frequency: ω = 2 π ξ, {\displaystyle \omega =2\pi \xi,} whose units are radians per second.
傅里叶变换也可以写成角频率形式: ω = 2πξ其单位是弧度每秒。
Results of eigenvalue, angular frequency, natural frequency and period
Both the MRC and MRT are curves versus angular frequency, not single numbers, although they sometimes are specified in terms of one point (or a few points) of the total curve.
MRC和MRT是随角频率变化的曲线,不是孤立的数值,尽管有时也用整条曲线上的一个或几个点表示。
Thus, an MRC is a curve of contrast versus angular frequency and MRT is a curve of T versus angular frequency.
因此,MRC是对比度随角频率变化的曲线,MRT是温度差A71随角频率变化的曲线。
This excitation frequency must be greater than the frequency difference which occurs between the two counter-propagating modes for an input angular frequency of the gyrometer corresponding to the intended measurement range.
该激励频率必须大于用于对应于旨在测量范围的激光陀螺测试仪的输入角频率的两个相向传播模式之间出现的频率差。
The solution in time will be a linear combination of sine and cosine functions, with angular frequency of ω, while the form of the solution in space will depend on the boundary conditions.
时间解是一个正弦 和余弦 函数的线性组合 ,而空间解的形式依赖于具体问题的边界条件 。
MRT is the minimum temperature difference between bars, at the entrance aperture of the sensor system, that can be resolved by the sensor, as a function of the angular frequency of the resolution chart in cycles per unit angle.
MRT是指在传感器系统人口孔径处,可被传感器分辨的条纹之间最小温度差,它是分辨率图的角频率,即单位角度的扫描周数的函数。
By introduced the micro-Doppler, this paper mainly analyzed the parameter extraction method, which can extract the angular frequency, amplitude and phase of the micro-motion target.
