摘要：
New high-precision Mn-53-Cr-53 data obtained for chondrules extracted from a primitive ordinary chondrite, Chainpur (LL3.4), define an initial Mn-53/Mn-55 ratio of. As a result of this downward revision from an earlier higher value of (9.4 +/- 1.7) x 10(-6) for the same meteorite (Nyquist et al. 2001), together with Al-26-(26) Mg and Pb-207-Pb-206 systems emerges in the early solar system.
