摘　　要：对系数均为有理函数的Riccati微分方程,我们在某些特殊条件下,给出了其亚纯解的增长级,极点收敛指数,零点收敛指数和不动点收敛指数的精确估计。For the meromorphic solution of differential Riccati equations whose coefficients are all rational functions, we give sharp estimates of the order of growth of it, and the exponents of convergence of the zeros, poles and fixed points of it for certain special cases.
