In the fourth chapter of the thesis , a study is made of the equation of interest rate - amount of circulating fund with infinite impulse disturbance in an open network . as far as linear and non - linear impulse disturbances are concerned , the conditions on which the system still remains stable under impulse disturbance and the conditions on which impulse disturbance leads to the changes of the stability of the system are discussed 本文第四章研究了开放网络中具有无限次脉冲扰动情形的利率?流通量方程,对于线性以及非线性脉冲扰动,本章都给出了脉冲扰动下系统仍然保持稳定的条件以及脉冲扰动引起系统稳定性改变的条件。
