The negative differential resistance characteristic equation of single electron transistor and metal oxide semiconductor hybrid structure SETMOS is simplified by fitting method. And a new approach is proposed for designing multi-scroll chaotic circuit with SETMOS.

利用拟合法简化了单电子晶体管与金属氧化物半导体混合结构器件——SETMOS的负微分电阻特性方程，提出了由SETMOS设计多涡卷混沌电路的方法。

So, a necessary and sufficient condition for the system to be stable is that the roots of the characteristic equation have negative real part.

因此，系统稳定的一个必要充分条件是特性方程的根有负的实部。

So, a necessary and sufficient condition for the system to be stable is that the roots of the characteristic equation have negative real parts.

所以，系统稳定的一个充要条件为：系统的特征根具有负实部。

Finally, we get the other two claims for simple graphs embedded in the surface of nonnegative characteristic number.

其他的两个结论也推广同时到了特征数非负的曲面上。

Routh-Hurwitz is used to determine that the characteristic equation has negative real root, and Center-Manifold theorem is used to study the stability of autonomous differential system in the case of hyperbolic and non-hyperbolic at the equilibrium point.

利用Routh-Hurwitz判定特征方程有负实部根，并利用中心流形定理研究了自治微分系统在平衡点处双曲和非双曲情况下的稳定性，由此产生系统趋于不同稳定点时病毒分裂的临界值，同时利用数值模拟验证了分析的合理性。
