| 摘 要： | 在应用文献1]方法的过程中，笔者改用博氏变换对稳态反应部分进行逆变换计算，而对瞬态反应部分直接用傅氏系数表示计算。对于相位调整，给出了所调整的实部Ak及虚部Bk的计算式及3种调整的方法。

| Abstract: | On use of the method of document 1], that is tnade changes in using Fourier inverse transform to the steady state response and the transient state response is expressed directly by use of Fourier coefficient. In addition, on the phase angle adjustrnent the expressions of real part Ak and imaginary part Bk adjusted and three procedures are given. |
