摘　　要：研制了用于全面禁止核试验条约现场视察的移动式37Ar快速测量原型系统。进行了移动式37Ar快速测量原型系统演示活动。演示活动通过车载运输、模拟样品快速分离纯化测量、地下样品快速取样分离纯化测量、取样有效性四个场地试验和三次实验室验证测试,全面展示和验证了移动式37Ar快速测量原型系统的技术状态和性能指标。演示结果表明:移动式37Ar快速测量原型系统最小探测下限满足探测当量大于1kt的地下核试验的要求,且具有“机动、快速、小型”的特点,但系统仍需在降低探测限、增强稳定性和自动化程度等方面开展进一步研究工作。A prototype of Movable Argon-37 Rapid Detection System for the mission of on-site inspection under the CTBT was devolped. In order to demonstrate the performance and its feasibility for OSI, the demonstration of MARDS-Ⅰ was held. In the period of the demonstration, the specification and technical capability of MARDS-Ⅰ was demonstrated by four experiments: experiment on vehicle transportation in rugged countryside; experiment on rapid separation, purification and measurement of simulating samples; experiment on rapid separation, purification and measurement of underground samples; the effectiveness of sampling process. These experimetal results are certified scientifically by gas chromatograph analysis in laboratory. The results show that the MDC of the system is less than 1 Bq/m^3 that meet the practical requirements of OSI in field for detecting 1 kt underground nuclear explosion during a period of several months after the explosion. MARDS-Ⅰ is movable, rapid and in small size. Otherwise, there is still room for further improvement of the system, e.g. reliability enhancement, reduction of the MDC, upgrading automation of system.
