摘　　要：介绍了利用硼中毒法测量微型临界堆芯硼中毒效应的实验研究结果。为了研究硼酸在该堆芯中的中毒效应,利用硼中毒法采用数字反应性仪和自动电位滴定仪及秒表测量了硼微分价值、堆芯临界硼浓度、堆芯后备反应性等。实验结果表明:实测值与理论计算值相符,结果可信;该实验结果可用于验证理论计算,也可为该堆型的带功率运行提供参考。The paper introduces the experimental results of boron poison effect on the micro critical core using boron poison method. In order to study boron poison effect on the core, the experiments measure boron differen- tial worth, spare reactivity and critical boron concentration using digital reactivity meter, automatic potentiomet- ric titrater, and stopwatch. The experiments show that the experimental results are correspondent with the theo- retic calculation results, they are believable; the results can be used for validating theoretic calculation, and can provide reference for the power operation and experiment on the same type core.
