The integro-differentialequation of parabolic type often occurs in applications such as heat conduction in materials with memory, compression of viscoelastic media, nuclear reactor, dynamics, etc.
抛物型积分微分方程多出现在记忆材料的热传导、多孔粘弹性介质的压缩、原子反应、动力学等问题中。

In this paper , we consider the Expanded Mixed Finite Element Method and mixed covolume method for the quasilinear parabolic integro-differentialequation and quasilinear parabolic problem.
With the aid of the projective operator technique, an integro-differentialequation for the porbability density and an approximate equation for the mean first-passage time (MFPT) have been derived.
