摘　　要：研究了溶液温度与溶液PH值对硼B/BaSO4/BaGrO4延期药燃烧速度的影响。通过正交试验得出:随着溶液温度的升高,所制得的延期药延期精度提高;反应溶液温度为45℃,PH值为5时,所制得的延期药燃速极差最小,从而得到B/BaSO4/BaGrO4延期药制备的最佳工艺条件。The effects of solution temperature and pH value on the combustion rate of boron B/BaSO4/BaGrO4 delay composition were studied.The results of orthogonal test show that:with the increase of solution temperature,the delay precision of the delay composition is improved;when the temperature of reaction solution is 45℃and the pH value is 5,the range difference of burning rate of the delay composition is the smallest,thus the best process conditions for the preparation of B/BaSO4/BaGrO4 delay composition are obtained.
