An approach is used to find out the present time approximate values of the characteristic amplitudes, the spectral densities, the intensties and the frequencies of the Primordial Gravitational Waves (PmGW), in the spatially perturbed Friedman - Robertson - Walker (FRW) adiabatically expanding Universe. The temporal variation of the magnitude of the time gradient of the characteristic amplitudes of the PmGW is calculated in spatial perturbed FRW Universe. The obtained results via this non-conventional approach may be of interest to shed some light on the possibilities of searching for the PmGW at definite frequency bands by the existing and the future networks of detectors.
