论文进一步研究了负荷模型的可辨识性，对负荷模型参数不惟一做了定性分析，研究了实际负荷模型的模型参数取值区间，和不同电压等级电网的负荷模型折算问题。
The study demonstrated that linear visco - elastic parameters of rheological models built by theoretical modeling methods were constant while nonlinear visco - elastic parameters were not constant and changed as stress level changed and that visco - plastic parameters determined the shape of stress - strain curve
研究表明：运用模型理论建立的流变模型的线性粘弹性参数在低应力水平下是惟一的，但非线性粘弹性参数不惟一，并随应力水平的变化而变化，而粘塑性参数的大小决定了应力应变等时曲线的形状。
