摘　　要：据 1 42 7～ 1 971年汉族家谱和圆形分析 ,表明男婴出生率亥时最高 ,申时最低 ;女婴出生率子时最高 ,戌时最低 .男婴、女婴平均出生高峰时间分别为 2 2时 49分和 2 3时 2 5分 ,二者差异不显著 (P >0 .0 5 ) ,男婴和女婴合并为 2 3时 1 1分 .男婴、女婴夜间出生率比白天分别高1 2个和 1 1个百分点 ,差异均极显著 (P <0 .0 1 ) .男婴阳时、阴时出生率分别为 42 .65 %和5 7.35 % ,差异极显著 ;女婴分别为 46.78%和 5 3.2 2 % ,差异接近显著 (P =0 .1 0 ) .古代和近现代男婴最大出生率均出现在亥时 ,女婴均在子时 .男婴、女婴的出生时辰与出生月份之间均存在显著相关 .随着产妇年龄的增加 ,男婴出生时间似有推迟趋向 。Based on demographic data from 1427 to 1971 from a Chinese (Hans) family tree and circular distribution analysis, the authors show that the highest male birth rate was 16.04% from 21:00 to 23:00 in a 24-hour day, which was 3.89 times higher compared with the lowest 4.12% from 15:00 to 17:00. For girls, the highest birth rate was 20.09% from 23:00 to 01:00 and 5.46 times higher than the lowest 3.68% from 19:00 to 21:00. The mean birth peaks of boys and girls were at 22:49 and 23:25, respectively, and the difference was not significant (P > 0.05). The mean time for both boys and girls was at 23:11. Birth rates at night (17:00 ～ 05:00) were 12% and 11% higher than in daytime (05:00 ～ 17:00) for boys and girls, respectively, and both of the differences were highly significant (P < 0.01). The birth rates of boys were 42.65% in Yang hours and 57.35% in Yin hours, with a highly significant difference. The female births were 46.78% in Yang and 53.22% in Yin hours, respectively, with a nearly significant difference (P = 0.10). The peak birth hours of boys in both ancient (1427 ～ 1840) and modern (1841～1971) times were 21:00 ～ 23:00, whereas the peak hours of girls were 23:00 ～ 01:00 in these times.The birth time of boys during the day seems to be delayed as the age of mothers increase, but the linear regression is not significant.
