探讨黄毛鼠（Ｒａｔｔｕｓｒａｔｔｉｏｄｅｓ）胴体重与体重、胴体重与睾丸发育的关系。证实黄毛鼠的胴体重与体重是同步增长的，两者呈非常显著的线性相关；平均胴重率为０．７３６２±０．００７８；全年整个种群的睾丸随胴体重增加而同步发育，它们的线性回归方程为：ｙ＝－０．４６６４＋０．０２１１ｘ），睾丸平均增长率为０．０２１１。
To investigate the relationship between carcass weight and body weight, carcass weight and testicular development in Rattus ratti. The results showed that the body weight and body weight of rodents increased synchronously with a significant linear correlation between them. The average body weight was 0.7362 ± 0.0078. The testicles of the whole population developed synchronously with the increase of carcass weight, Their linear regression equation is: y = -0.4664 + 0.0211x), the average testicular growth rate of 0.0211.
