为什说ramp up很慢的transient等效于dc

我需要量schmitt trigger的V-hysteresis
在网上学习的时候看到这样一句话:You can run a DC sweep in the positive direction and the negative direction, then overlay the two curves. Or this can all be done with one single transient simulation, including the hysteresis switching dynamics。
我做了一下simulation,只有ramp up很慢的transit也可以和DC测量的值相近,请问原因是什么?
谢谢

因为某一个时间段内,电压变化很小,接近直流,容易到稳态。所以跟直流扫描结果差不多。斜率小嘛
