局域预位移的震源过程为有限源传播，全域预位移为有限源与瞬时面源。

The source process of partial area pre-displacement is finite moving source and that of whole area pre-displacement is combination of finite moving source and instantaneous source.

提出一种基于半导体器件漂移扩散模型并结合交替方向隐式时域有限差分(AD I - FDTD)法的新型全域FDTD法。

A novel global FDTD scheme based on a drift-diffuse model of semiconductor combined alternating direction implicit finite-difference time-domain (ADI-FDTD) method is presented in this paper.
