 通过我们与联合王国以及其他伙伴的合作，美国的核查研究举措为应对重大的技术挑战发展了能力，如监测弹头，包括监测贮存库中非部署弹头的能力，以及按类型区分弹头的能力。 美国正在开展核弹头建模和计量活动，目的是制定一套全面的核弹头和组件识别标志。由此产生的数据将支持对可能因今后的条约核查活动显示的敏感信息进行评估，并将进一步指导今后在辐射探测和信息保护领域的研究和发展工作。 美国正在开展核弹头生命周期“端对端”监测能力现场演示和评价，包括在内华达国家安全场所进行的弹头贮存和运输监测演示和评价。目前正在发展和评估各种技术，据以向可能进行监测的一方做出保证：一定会在其整个生命周期、包括在长期贮存和拆除期间衡算和跟踪核弹头。 在 2018 年期间与能源部国家实验室开展的一项重要工作中，美国将研究在监测下拆除核武器的程序和技术，其基础是一个为期三年的监管链项目，该项目以 2014 年 1 月的演示实验而告终，该项目： 为测试和评价监管链技术的技术研究与发展开发了一个有代表性的环境，并开展了一系列技术评价活动；以及 为支持对弹头所负说明之责开发技术，包括评价一个利用射频识别标签来计算视察物品的实时系统的潜在可行性，并测试其在视察情境中可能的运用。 美国还在开展研究和发展工作，以求加强今后其他的军备管制条约，包括： 支持《全面禁试条约》的技术，包括进行实地试验和演示，据以促进我们对地下核事件地震特征的认识； 这些活动包括评价《全面禁试条约》相关技术的有效性和侵扰性，以及以最佳方式进行目视观测、地震和声波探测、多光谱成像以及放射性核素输送和计量；以及
and,  enabling the testing of technology in operational environments. • Through our work with the UK and other partners, U.S. verification research initiatives develop capabilities to address major technical challenges, such as monitoring of warheads, including non-deployed warheads in storage, as well as capabilities to distinguish warheads by type.  The United States is conducting a nuclear warhead modelling and measurement campaign to establish a comprehensive nuclear warhead and component signature set. The resulting data will support assessment of sensitive information that could be revealed as a result of future treaty verification activities, and will further guide future R&D in the areas of radiation detection and information protection.  The United States is conducting field demonstrations and evaluations of nuclear warhead lifecycle “end-to-end” monitoring capabilities, to include warhead storage and transportation monitoring demonstrations and evaluations at the Nevada National Security Site. Technologies are being developed and assessed to provide assurance to a potential monitoring party that nuclear warheads are accounted for and tracked throughout their lifecycle, including during long-term storage and dismantlement.  In a major effort through 2018 with the Department of Energy’s National Laboratories, the United States will examine procedures and technology required for the monitored dismantlement of nuclear weapons, building on a three-year chain-of-custody project that culminated in demonstration experiments in January 2014, which:  developed a representative environment for testing and evaluating technology research and development (R&D) of chain-of-custody technologies and carried out a series of technical evaluations; and,  developed technologies to support accountability of warheads including evaluating the potential feasibility of a real-time system for counting items of inspection using radio-frequency identification (RFID) tags and tested its potential use in an inspection scenario. • The United States is also pursuing R&D to enhance other future arms control treaties, including:  technologies to support the CTBT, including completion of field experiments and demonstrations to further our understanding of underground nuclear event seismic signatures;  activities evaluating CTBT-related technologies for effectiveness and intrusiveness, optimizing visual observation, seismic and acoustic sensing, multi-spectral imaging, and radionuclide transport and measurement; and,
