| 摘 要： | In this paper we discuss singular perturbations offirst boundary value problem for higher order ellipticequations of two parameter and obtain the asymptoticexpression for the formal solution containing two-parameter as well as the estimation of its remainderterm.These results are the extensions of(2)and(3). |
