摘　　要：液态铅铋合金是加速器驱动次临界系统(ADS)重要的散裂靶材料和冷却剂候选材料,其热力学物理性质是ADS研发过程中必须解决的基础问题。以Fortran语言为基础编制的程序NCEPU-LBETP,实现了对液态铅铋合金熔沸点、密度、比热容、动力粘度和热导率的计算,且计算步序大大简化,精度得到提高。并对液态铅铋合金热物性程序进行了校核,其结果和国内外相关计算结果符合良好,这表明物性程序是成功的。Liquid lead-bismuth alloy （LBE） is important spallation target materials and candidate coolant materials in ac- celerator driven subcritical system （ADS）. Its thermophysical property is the basic problems in ADS R＆D. NCEPU-LBETP program bases on FORTRAN Language to realize the calcula- tion of characteristic temperatures, density, specific heat, viscos- ity and thermal conductivity of liquid lead-bismuth alloy. The calculating step sequence is simplified greatly and the accuracy is improved. Finally, the program was checked. The numerical results coincide with the results fi＇om domestic and overseas very well, showing that the program is successful.
