| Abstract: | Through reducing the analysis expression of boundary value problem on a class of second-order linear homogeneous differential equation with constant coefficients,the paper presents the solution's formal similarity.This similar structure reflects that the class equation can be obtained by the product of several fractions and the graphs have similarity as well.The character resembles that of the real number.The result obtained is beneficial to understand the inherent laws of relevant engineering science and design of the practical analysis software.Furthermore,it promotes the progress of equation theory |
