| 摘 要： | 的探索男性自杀率和男女自杀比随年龄而变化的动态规律。方法用Manoel发表的WHO男和女各年龄组自杀率的资料 ,进行曲线拟合。结果男性自杀率随年龄而变化呈指数曲线规律 ,曲线方程为ln( 4 3 .3 5 -Y) =4.2 876-0 .0 5 5 2X ,R2 =0 .9978,男女自杀率比值随年龄而变化呈抛物线规律 ,曲线方程为Y =1.3 76 0 .12 46X -0 .0 0 14 8X2 ,R2 =0 .973 0。结论 ( 1)社会科学象自然科学一样 ,可用数学方法精确测算 ;( 2 )从年龄方向上看 ,男女自杀比在中年时最高。

| Abstract: | ObjectiveTo explore a rule between male suicide rate and age as well as a rule between male versus female ratio and age . MethodsIt was curvillineally fitted for WHO data of male and female suicide rate multiple age group supplied by Manoel J.Results There was an exponential curvillineal correlation between male suicide rate and age . Its curvillineal equation was: ln(43.35-Y)=4.2876-0.0552X,R 2=0.9978. There was a parabolic correlation between male versus female ratio and age.Its curvillineal equation was :Y=1.376 0.1246X-0.00148X 2,R 2=0.9730.Conclusions(1) Social science may be exactly measured and calculated as natural science (2)From child to old age , male versus female suicide ratio was the highest at adulthood. |
