讨论了超光速研究的历史背景和在狭义相对论框架内进行工作的可能性；指出已有的实验（用单光子、激光脉冲和微波）在量子隧穿过程中呈现出的超光速行为，是在特定物理条件下才有的。认为经典电报员方程与Klein-Gordon方程的相似，使得前者可用于粒子隧穿和超光速现象的研究。讨论了不久前发表的王力军博士的超光速实验，展望了超光速研究的未来。

In this paper, the historic background of the study on faster than light (FTL) and the possibility of working within the frame work of special relativity are discussed. The previous experimental studies with single photon, laser pulse and microwaves have revealed superluminal behavior in the quantum tunneling process. That phenomenon exists only in the case of special physical condition. The analogy between classical Telegraphist equation and Klein-gordon equation can be used to study particle tunneling and superluminal behavior. A discussion on the FTL experiment by Dr. L. Wang recently is included. Remarks on the future of FTL research is given in this article.
