摘　　要：采用自制的试样分解装置,把BBr3试样水解为氢溴酸和硼酸,通过Fajans法溴化银沉淀滴定和甘油硼酸酯酸度滴定,分别成功的测定了试样中溴和硼的含量,该方法尚未见报道.Hydrolyze specimen of Boron tribromide to HBr and H3BO3 with self-made device. The contents of Br^- and B^3＋ in specimen were measured successfully by Fajans precipitationtitration and glycerolboric acid strengthened acid-basetitration method. This method did not been reported by now.
