The dynamic behaviors of a kind of SIR epidemic model with two different vaccination strategies and saturation infectious force are researched.
研究了两类不同免疫方式下具有饱和传染力的SIR流行病模型的动力学行为。

The model can depict radial force and electromagnetic torque generated in the motor more accurately in the region of magnetic saturation.
在大电流饱和状态下,该模型有效地描述了电机产生的径向悬浮力和电磁转矩。

The results show that the magnetic anisotropy of soft magnetic materials with very low coercive force can be measured successfully with ring specimen by the law of approach to saturation.
