作为最早将DNA证据用于司法实践的国家之一,美国对DNA证据的采信经历了一个从盲从、迷信到理性接受的发展过程。为了使DNA证据在司法实践中发挥更大的价值,必须科学、理性地面对DNA证据,建立DNA技术标准化和质量控制体系等程序规则,完善DNA鉴定程序规则已成为我国法庭科学亟待解决的重要问题。 As one of the earliest countries to apply DNA evidence to judicial practice, the United States has gone through a process of blind faith, superstition, and rational acceptance of DNA evidence. In order to make DNA evidence more valuable in judicial practice, it is necessary to deal with DNA evidence scientifically and rationally, to establish rules and procedures of DNA technology standardization and quality control system, and to improve the rules of DNA appraisal procedure, which has become an important issue to be solved in forensic science in our country problem.
