Results of an investigation of the absolute energy distribution of seven standard stars (Beta Ari, Gamma Ori, Beta Tau, Alpha Leo, Eta UMa, Alpha Aql, and Alpha Peg) are presented. The observations were made in the period between 1981 and 1987 with three telescopes and at three observation stations in the Tien Shan Mountains. The internal accuracy is 3 percent in the region from 3200 A to 3700 A, 2 percent from 4000 A to 6000 A, and 5 percent from 6000 A to 7500 A. A comparison of the findings was made with the present stars' energy distributions, which were used in the first and second editions of the Alma Ata spectrophotometric catalog. The characteristics of the observation cycles and the energy distribution in the standard-star spectra are presented in tables.
