天体引力波源所产生的引力辐射,使地球上共振型圆柱天线产生10~(-17)cm～10~(-22)cm的纵向振动.在正常情况下要求天线系统有小于或接近10~(-11)的可透性.用弹性体支承时可透性T 是:Z_0是外振源的振幅,A 是经过减振系统之后的振幅,ω_0是减振系统的自振圆频率,ω是外振源的圆频率,β是衰减系数.若ω(?)ω_0则T(?)(ω_0/ω)~2.
The gravitational radiation generated by the gravitational wave source of the celestial body causes the longitudinal vibration of the resonant cylindrical antenna on the earth to produce 10 ~ (-17) cm ~ 10 ~ (-22) cm. Under normal circumstances, the antenna system is required to have the antenna system smaller or closer to 10 ~ -11) Permeability T supported by the elastomer is: Z_0 is the amplitude of the external vibration source, A is the amplitude after passing through the damping system, ω_0 is the natural circular frequency of the damping system, ω is The external frequency of the circular source, β is the attenuation coefficient, if ω (?) Ω_0 T (?) (Ω_0 / ω) ~ 2.
