摘要

摘要:
介绍了激光-等离子体相互作用产生正电子的相关实验和数值模拟研究进展。简要回顾了激光-等离子体相互作用正电子的发现过程及激光-等离子体作用产生正电子的三种物理机制；详细地叙述了激光与物质相互作用产生正电子的两类典型实验方式（即直接方式和间接方式）及相关的实验和数值模拟结果；对激光-等离子体相互作用产生正电子的研究进行了评述。从现有研究进展来看，目前理论研究和实验研究所获结论差异较大，还需要从激光设备、实验方案设计以及理论和模拟研究方面做大量细致的工作。

Abstract:
The history and development about the study of positrons generated by intense laser interaction with the plasmas are introduced. The mechanisms of the positron generation are presented. Specially, the typical experiment scheme (direct and indirect) of the positron generation, including important results about the experiment and computer simulation are described systemically. Eventually, the study of positron is reviewed and summarized. At present, the conclusions obtained from theoretical research and experimental research are quite different, and a lot of detailed work needs to be done in terms of laser equipment, experimental scheme design, and theoretical and simulation research.
