This paper touches upon gravitational radiant power and radiant angle distribution of space rectangular lattice arrays of mass quadrupole oscillators, and gives analytic expression. The calculation show that these arrays can generate narrow gravitational radiation wave beam which has the best directional property. The travelling wave typegravitational radiation theory, developed by Seki and his colleagues, may be regarded as a specific case of the work in this paper and can be derived naturally. Under the codition of ideal ultrahigh frequency acoustic resonance and perfect travelling wave type synchronism intensification, an numerical example calculated with our method shows that energy flux density of gravitational radiation of optimum direction of space array which consists of 100 CaS crystals of 30×30×0.03 cm3 would amount to 2.84×10-1 erg/cm2·s. This result shows the potentiality of crystal space arrays exciting high-frequency gravitational radiation.
