英文摘要	\To track the formation and evolution links of the millisecond pulsars (MSPs) powered by accretion and rotation in the Galactic field, we investigate the spin period (P) and spin-down power (over dot (E)) distributions of the MSPs observed at the wavebands of radio, X-ray, and gamma-ray. We find that all but one (119/120) of the gamma-ray MSPs have been detected with the radio signals (radio+gamma MSPs); on the contrary, nearly half of the radio MSPs (118/237) have not been detected with gamma-rays (radio-only MSPs). In addition, the radio+gamma MSPs are shown to be the relative faster and more energetic objects (< P > similar to 3.28 ms and < over dot (E)> similar to 4.5 x 10(34) erg s(-1)) compared with the radio-only MSPs (< P > similar to 4.70 ms and < over dot (E)> similar to 1.0 x 10(34) erg s(-1)), while the spin periods of these two MSP populations are compatible with the log-normal distributions by the statistical tests. Most rotation-powered MSPs (RMSPs) with the radio eclipsing (31/34) exhibit the radio+gamma signals, which share the faster spin (< P > similar to 2.78 ms) and larger spin-down power < over dot (E)> similar to 4.1 x 10(34) erg s(-1)) distributions than the non-eclipsing ones (< P > similar to 4.19 ms, < over dot (E)> similar to 2.4 x 10(34) erg s(-1)), implying the radio+gamma MSPs to be younger than the radio-only MSPs. It is noticed that the spin distribution of the accretion-powered X-ray MSPs shows a clustering phenomenon around similar to 1.6-2.0 ms, which is not observed in RMSPs, hinting that the RMSPs may experience the multiple possible origins. Particularly, all the three super-fast spinning RMSPs with P similar to 1.4-1.6 ms exhibit the non-eclipsing, and we argue that they may be the distinctive sources formed by the accretion induced collapse (AIC) of white dwarfs.
