摘要
本文对二阶常系数线性非齐次方程x'+Px'+qx=(a2t^2+a1t+a0)e^λ0^t建立了一组特解公式（1）-（9），当从实常数扩充到复常数时，公式（1）-（9）依然是正确的，从而扩大了这组特解公式的应用范围。
The article is about a group of particular solution formula(1 ) - (9) established for the linearnon- homogeneous equation of the secondorder constant coefficient: x'+ Px' + qx = (a2t2 + a1t + an1 ) eo'.When expanded from the actual constant to the complex constant,the formulas (1 ) - (9 )are still correct.thus they have enlarged the scope of the application of the particular solution formula.
