摘　　要：通过对B/BaCrO_4延期药配方及混药方式进行研究,并结合我国工业雷管的实际应用方式,采用铅延期体结构把此延期药装配成导爆管雷管进行测时,考察其延期精度和延期时间;此外,对延期元件进行了0.5a的自然贮存试验,检验其贮存后延期时间与延期精度的稳定性。结果表明:B/BaCrO_4延期药燃速稳定、延期精度高、贮存性能好,在一定范围内,延期时间与延期元件的长度基本为线性关系。Through studying the formulation and mixedway of B/BaCrO4 delay composition, and combined with practical application way of industrial detonators, the delay composition is adopted in the lead delay element which is assembled into non-electric detonator, so the delay time and its precision is inspected. The natural storage test of delay element is ean＇ied on for haft a year, the stability of delay time and delay precision after storage is a/so examined. The results show that B/BaCrO4 delay composition has stable burning rate, high delay precision and good storage performace, the delay time and length of delay element has the linear relationship in a certain range.
