摘　　要：介绍采用极限碳酸盐硬度法 (改进装置 )对水质稳定剂阻垢性能进行评价的方法 ,包括阻垢性能测定和评价指标、试验水温、水质稳定剂浓度、试验装置循环水量等的确定 ,并与阻垢率法进行了比较。实验表明 ,极限碳酸盐硬度法具有分辨率高、数据重现性好、指导意义明确、简单实用等优点 。An evaluation method for scalingretardation behavior of waterquality stabilizing agent by using ultimate carbonate hardness method has been presented, including measurment of scalingretardation behavier, as well as ditermination of evaluation indices, water temperature in test, concentration of waterquality stabilizing agent, and circulating water flow rate of the test facility etc., and a comparison with the scalingretardation rate method being carried out. Results of test show that the ultimate carbonate hardness method has many advantages, namely having high distinguish ability, good data reproducibility, clear and definite guiding significance, as well as simplicity and applicability etc., being suitable for evaluating the scalingretardation behavior of waterquality stabilizing agent used in circulating water treament at thermal power plants
