摘要：

We present precision measurements of the D0 and D+ meson lifetimes using approximately 7500 fully reconstructed D0 --> K-pi+, K-pi+pi+pi-, D+ --> K-pi+pi+, and charge conjugate decays. The data were accumulated by the Fermilab high energy photoproduction experiment E687. The lifetime of the D0 is measured to be 0.424 +/- 0.011 +/- 0.007 ps while the D+ lifetime is measured to be 1.075 +/- 0.040 +/- 0.018 ps.
