3) finite frequency positive realness
有限频率正实性
1.
Compared with positive realness,finite frequency positive realness is a new notion,and it also finds some important applications in control theory.

4) finite-frequency ray methods
有限频率射线方法
1.
The existing finite-frequency ray methods,including the Maslov ray summation and phase-ray method,can only partially simulate the basic physical process during which the finite-frequen- cy wave affected by Fresnel interference and medium heterogeneity scattering propagates.
