【摘要】 通过对钼系延期药各组分的性质的分析研究,从理论上探讨其异核结晶的结晶机理。实验证实,用降温析出法制备的钼系延期药秒量均匀、燃烧稳定,延期时间的标准差和极差都小于手工混制的延期药。更多还原

【Abstract】 The crystalline mechanism of heteronuclear crystalline is found out by theoretical analyzing the chemical property of molybdenum delay composition.It is tested by experiments that the molybdenum delay composition which is preparation with the method of decrease the composition liquid temperature,and some of its standard characters of time uniformity,combustion stabilization,delay time are better than the delay composition which is mixed by hand.更多还原
