A Galilean-invariant homogeneous-turbulence theory within Eulet'ian frame-work is proposed for the study of the snaall-scale turbulence. Twc>Galilean-invariant quantities, the one-time velocity covariance and the con','ection-freeresponse, are chosen as fundanaental ones instead of the usual two-tiune velocitycovariance and response. The Direct-Interaction formalism is applied to findgoverning equations for these two quantities. Using them, Kolmog;orov's lawnaay be derived with the reasonable estimate of Kolmogorov's constant. Thistheory is also applied to the evaluation of the Reynolds stresses in the inhomogene-ous turbulence with arbitrary mean flows. Results obtained are shown to coincidewith those from the previous work (A. Yoshizawa: J. Phys. Soc. Jpr?. 46 (1979)669 and 47 (1979) 1665), apart from a slight change of numerical factors.
