水解聚马来酸酐（ＨＰＭＡ）和氨基三甲叉膦酸（ＡＴＭＰ）的缓蚀和阻垢性能都有量佳浓度值，在要同条件下ＨＰＭＡ的缓蚀、阻垢性能优于ＡＴＭＰ，两种药剂的阻垢率均随Ｃａ＾２＋浓度的增加而提高，Ｄ ＰＨ为６～９时两种申报后率比较稳定。
There was an optimal concentration value of HPMA and STMP respectively for inhibition and scale prohibition. The inhibition and scale prohibtion effect of HPMA was better than that of ATMP in the same concentration . Inhibition and scale prohibition rate of HPMA and ATMP increased considerably with increasing of the Ca2+ concentration. The scale prohibition rate was relatively stable when PH=6--9.
