@MarvinH2_G2 @NjbBari3 @hjelle_brian It's actually way more complicated than that ideal due to external factors and not just properties of the model itself. The intuition behind bifurcations is pretty simple here BTW. With high R, you will have massive overshoot i.e. "too much" immunity to just barely stop the wave.
@MarvinH2_G2@NjbBari3@hjelle_brian由于外部因素，而不仅仅是模型本身的特性，它实际上比理想情况要复杂得多。分岔背后的直觉在这里非常简单。顺便说一句，高R时，你会有巨大的超调，即“太多”的免疫力，几乎无法阻止波浪。
