| 摘 要： | 将数学解高次方程的插值估算基本原理与工程经济分析的常用复制表相结合，提出了动态投资回收期的两种值估算法－－直接插值估算法与间接插值估算法，直接插值估算法是以净现值函数为依据，插值估算得出使净现值为零的时间，即动态投资回收期，间接插值估算法对将净现值函数变换为一种没有经济涵义的抽象函数，插值估算得出使该函数为零时的时间，即动态投资回收期。

| Abstract: | By combining the fundamental principle of interpolating estimation in solving mathematical higher equations with compounding interest table in the analysis of engineering economy, the author presents two methods of interpolating estimation for the dynamic payout period of investment which are direct interpolating estimation and indirect interpolating estimation. The direct interpolating estimation is based on the N PV function by the time when N PV reaches zero, i.e. dynamic payout period of investment, is calculated. The indirect interpolating estimation changes the N PV function into a function without economic meaning by the time when N PV reaches zero, i.e. dynamic payout period of investment, is calculated. |
