Residual charges produced in previous partial discharges (PDs) are considered as one aspect of memory effects that affect subsequent discharge behavior. In this paper, we review past studies about memory effects induced by residual charges during successive PDs. At first, surface charge dynamics for cavity and needle-to-dielectric discharges are presented. Subsequently, three methods used to unravel the memory effects are described, e.g. conditional distribution, pulse sequence analysis (PSA) and chopped PD (CPD). Then effects of residual charges on PD inception, discharge propagation and collective behavior are summarized. In addition, contributions of residual charges to the transitions between discharge modes and discharge patterns are presented. At last, some problems relevant to the memory effects are discussed, followed by suggestions for future work.

从残余电荷引起的记忆效应理解局部放电行为：综述

先前局部放电 (PD) 中产生的残余电荷被认为是影响后续放电行为的记忆效应的一个方面。在本文中，我们回顾了过去关于连续 PD 期间残余电荷引起的记忆效应的研究。首先，介绍了腔放电和针-电介质放电的表面电荷动力学。随后，描述了用于解开记忆效应的三种方法，例如条件分布、脉冲序列分析（PSA）和斩波局部放电（CPD）。然后总结了残余电荷对局部放电开始、放电传播和集体行为的影响。此外，还介绍了残余电荷对放电模式和放电模式之间转换的贡献。最后讨论了与记忆效应有关的一些问题，
