测谎技术进入我国已有十余年 ,然而由于其可靠性未得到有效保障 ,以及相应制度的滞后 ,造成其难以被认定为证据而步入法庭。本文对国外从测谎技术到测谎鉴定的发展变化进行分析后认为 ,我国只要加快创造条件和建构制度 ,测谎技术迟早会成为鉴定证据。 Polygraph technology has been in our country for more than ten years. However, its reliability has not been effectively guaranteed and the lag of the corresponding system has made it difficult to be admitted as evidence. After analyzing the development and changes of polygraph technology and polygraph identification from abroad, this paper argues that as long as China accelerates the creation of conditions and construction system, the polygraph technology will become the evidence of identification sooner or later.
