The mainly work has : the relation of boron contents and the average liner burning rate, through which chooseing suitable boron contents in these delay compositions ; the impact of different particle diameters on delay characteristics, by the means of granularity classfication ; the impact on delay characteristics through pre - treatment to the raw materials and improvement of mixing means ; and some other factors, such as the pressure of charge, loaded times, the charge mass of delay composition ; at last, the mechanical intensities of boron based delay compositions with some different binders
主要的研究內容有： b含量與線性平均燃速的關系，並由此選用b含量適合的延期藥；通過原材料的細化與粒度分級，研究了粒度對延期性能的影響；原材料預處理和混藥方式對延期性能的影響；以及影響延期性能的其它因素，如壓藥壓力、壓裝次數、裝藥量等；最後還研究了含不同粘合劑的硼系延期藥的壓藥藥柱強度（機械強度）等。
