迟迟合成
Examples
- ( 4 ) with suitable binders , boron based delay compositions have better mechanical intensities
( 4 )选择合适的粘合剂可以提高延期药压药药柱的强度。 - ( 2 ) to b - cuo delay composition , the smaller particle size , the lower average linear burning rate , the better delay precision , and the higher mechanical intensities
( 2 )对b ? cuo延期药，原材料的粒径越细，其平均燃速减小；而延期精度提高，压药强度增强。 - ( 3 ) to b - cuo delay composition , after pre - disposal to the raw materials and improvement of the mixing means , the compositon is more active , and the burning rate is higher , the delay precision is better
( 3 )对b ? cuo延期药，原材料经过预处理和改善混药方式后，可增加组分的反应活性，使燃速增加，延期精度提高。 - 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
主要的研究内容有： b含量与线性平均燃速的关系，并由此选用b含量适合的延期药；通过原材料的细化与粒度分级，研究了粒度对延期性能的影响；原材料预处理和混药方式对延期性能的影响；以及影响延期性能的其它因素，如压药压力、压装次数、装药量等；最后还研究了含不同粘合剂的硼系延期药的压药药柱强度(机械强度)等。
