英文摘要We analyze the properties of the binary millisecond pulsars (BMSPs), detected at radio and gamma-ray wavelengths, and further probe their correlations with the binary orbital parameters and companion masses to trace the possible evolutionary histories. We find that the BMSPs with the lowest-mass companions, (0.006-0.06)M-circle dot, have short orbital periods P-orb < 1 day and in most cases (23 out of 25) have been detected in both radio and gamma-rays. On the other hand, the BMSPs with companion massesM(c) = (0.06-0.4)MP(orb)range, from 0.1 to 200 days, and nearly half of them show radio+gamma(53 out of 103), while the remaining ones emit only radio waves. We suggest that the two groups, with low-mass and more massive companions, respectively, experienced different evolutionary histories. Concerning the sources with the more massive companions, the radio+gamma BMSPs have on average significantly shorter spin periods (< P > = 3.37 ms) than the radio-only BMSPs (< P > = 4.73ms). We propose that the latter systems are a later evolutionary phase of the former ones.
