内容摘要：测谎技术建立在心理学、生理学、电子学等学科的研究成果之上。其核心即在于“心理刺激与生理反应的对应伴生关系”。由于测谎技术及测谎结论具有科学性、互动性、客观性和有限性，所以在实践中对其证据属性产生了极大的争议。而测谎恰能完成诉讼证明活动中证据的本质属性——关联性证明的作用，所以其应该被采纳为证据，但需要其他证据来补强，其否定结论证明力也大于肯定结论证明力。任何一种认识手段或方法，只要有助于我们正确的澄清事实，且是真实合法的，我们都应该通过对原有证据理论体系和诉讼程序制度的完善来正确地加以利用，让它服务于我们的诉讼制度。

Abstract: Polygraph technology is based on the research results of psychology, physiology, electronics and other disciplines. And the core of this technology is the mental stimulation and physiological reaction corresponding associated relations. Because polygraph technology and polygraph conclusion have the qualities of scientific, interactive, objective and limited, they have caused a great of controversy in practice. But in fact it is the polygraphs that can finish the work of testify to relevance of essential attribute of evidence in litigation proof activities. So they should be accepted and used as a kind of evidence that need extra evidences’ cooperation. And its negative conclusion proof force is stronger than its probative force. As long as a kind of method of cognition is real and good for us to clarify fact correctly and legally, we all should take use of it and let it serve our litigation system through the integrity of the original evidence theory system and litigation procedure system.
Key words: Polygraph conclusions, Polygraph principle, Evidence attribute， Applicable principle
