Positive correlations between the orbital period $P_{\\rm b}$ and eccentricity $\\epsilon$ are found in two classes of MSP binaries with a He WD and with a CO/ONeMg WD, though their trends are different. The distribution of $P_{\\rm b}$ is not uniform. Deficiency of sources at $P_{\\rm b}\\sim35-50$~days (Gap 1) have been mentioned in previous studies. On the other hand, another gap at $P_{\\rm b}\\sim2.5-4.5$~days (Gap 2) is identified for the first time.
