摘要: This paper is a continuation of [1]. In this paper, the solutions of the more general linear partial differential equation form i+j≤n aijpiqjφ=0 with two independent variables and constant coefficients are discussed in detail. The general solution which can be used in the approximation to the conditions of the definite solution of the practical problems is presented. To illustrate the use of the results obtained in this paper, some practical examples in mechanics are given.
