摘要
通过测定 53种多硝基化合物在 50 %发火概率下的静电火花感度EES,发现由Skinner等人在热分解速率常数k =10 3s- 1 下建立的EES与温度倒数的半对数关系表达式随着化合物种类的不同而不同。分析结果表明 ,含能材料初始热分解的化学机理及其晶体中分子的相互作用对电火花点火起决定性的作用。
The spark energy, E ES , required for 50 percent initiation probability of 53 polynitro compounds was determined. It was found that semilogarithmic relationship by Skinner et al (1998) between the E ES values and reciprocal temperatures for thermolysis rate constants k=103 s -1 has different forms for different groups of the compounds. The fact is discussed and conclusion is made that both the chemical mechanism of primary thermolysis of energetic materials and intermolecular interaction factors in their crystals play decisive roles in their initiation by electric spark.
