摘　　要：设计出求解时域支集无限型任意激励的非齐次线性自治系统的一种长效精细算法(简称：HHPD-LF),特点是：传递矩阵H属“一次计算,终生使用”,它突破了时域有限的约束,没有矩阵求逆、没有对右端函数的周期性要求,在一定程度上适合于任意形式的右端激励。理论与算例表明HHPD-LF算法十分有效。This paper designs a new long acting HHPD （ah. HHPD- LF） aiming at non-homogeneous linear automatic system on infinity time domain, whose characters are that the transfer matrix is “computed once for ever useful”. It does not only breaks through limitation of time domain, but not demand matrix inverse and periodicity of the excitement function as well. Thus it adapts to excitement in arbitrary form at some level. The theory and examples indicate that the long acting HHPD- LF is in force.
