摘要

Template identification technology (TIT) is designed for the scenarios where a batch of disarmed nuclear weapons or components would be dismantled to observe a nuclear disarmament treaty.The core function played by the TIT is to make a judgment on whether the verified item belongs to a certain kind of nuclear weapons or component (NW/NC) or to which kind the verified item belongs.This paper analyses the functions played by the TIT in the process of NW/NC dismantlement,and proposes that two phases would be followed when applying the TIT:firstly to establish NW/NC templates with a sample of size n drawn from a certain kind of disarmament NW;secondly to authenticate NW/NC by means of the TIT.This paper also expatiates some terms related to the concept of the TIT and investigates on the development status of NW/NC TIT based on radiation signatures.The study concludes that the design of template structure is crucial to the establishment of an effective TIT and that starting from different research angles and aiming at the same goal of classification different template structures and corresponding template identification methods can be built up to meet specific identification requirements.
