摘要：

The decay modes D(s)+ --> pi-pi+pi+ and D+ --> K-K+K+ have been studied in the hadroproduction experiment WA82. The following ratios of branching fractions have been measured: B(D(s)+ --> pi-pi+pi+)/B(D(s)+ --> phipi+) = 0.33 +/- 0.10 +/- 0.04, B(D+ --> K-K+K+)/B(D+ --> K-pi+pi+) = 0.057 +/- 0.020 +/- 0.007, B(D+ --> K-K+K+)/B(D+ --> phipi+) = 0.49 +/- 0.23 +/- 0.06.
