This is a stiff equation, so an explicit solver may become unstable.
这是一个刚性方程,因此显式求解器可能会变得不稳定。
In chemical kinetics, the model often becomes a stiff equation system because reactions occur on vastly different time scales, requiring implicit integration to remain stable.
在化学动力学中,由于反应发生在差异巨大的时间尺度上,模型常变成刚性方程组,需要隐式积分才能保持稳定。
