摘　　要：在零功率实验装置上 ,反应性是表征实验系统临界性的主要参数 ,该装置采用周期测量系统测量装置功率上升的二倍渐进周期 ,再根据渐进周期与反应性的关系得到系统反应性。通过装置上的运行实验表明 :测量数据是可靠的。对零功率装置的周期测量系统进行了介绍。并阐述得到系统反应性的基本原理和过程。In a zero power assembly, the reactivity is the main parameter of the situation of practical system. By using the period measuring system, we can measure the 2 times period of the power raising, and then based on the relation of the period and the reactivity, we can obtain the reactivity .The data are proved to be reliable through many practice on the sub critical assembly. In this paper the period measuring system and the principle of how to obtain the reactivity are described.
