摘要: 性成熟时间是物种进化的重要参量。本文以鸟类为研究对象，根据48种鸟类的性成熟时间与体长数据，分析了二者之间的相关性。拟合了21种鸟的性成熟时间与体长的资料，得到线性关系式y = 0.029x + 0.34，相关系数为R2 = 0.76。工作中还发现这一线性关系具有一定的普适性，例如在一些哺乳动物中也成立。根据所得鸟类性成熟时间与体长的线性公式，我们估算了其余27种鸟类的性成熟时间。
Abstract: The sexual maturity time is an important parameter in the evolution of species. Based on the data from 48 birds, the correlation between the sexual maturity time and body length was analyzed. Then, a linear function y = 0.029x + 0.34 was obtained by fitting the data of 21 birds, and the corre-lation coefficient is R2 = 0.76. We found that the linear relationship of the two factors can be gener-alized to other species, such as some mammals. Based on the linear function, we estimated the sex-ual maturation time of the remaining 27 birds.
