摘　　要：利用MCNP程序计算了不同燃耗下脉冲堆调节棒的微分价值，并采用周期法实验测量了调节棒的微分价值，对比了在不同燃耗下脉冲堆调节棒的微分价值实验值和理论计算值。结果表明：随着脉冲堆燃耗的加深，调节棒在高度200mm以下微分价值变化不明显，在高度200.390mm时，燃耗越深，微分价值越大，理论值与实验值符合很好。In this paper, M onteC arloN -Particle(MCNP) program is used to calculate and analyze the differential worth of the adjuster rod(rod D) for Xi^an Pulsed Reactor with various burnup, and period method is used to measure the differentialworth of rod D experimently.The experimental values of the differential worth of rodD are comparedwith theorical ones. The i^esults indicate that the differential worth of rod D does not change significantly when the height of rod is less than 200 mm, and while the height of rod D is 200 - 390 mm, thedeeper theburnup is , the greater 1^he differential worth will be.
