多硝基化合物的静电火花感度与热分解参数的关联（英）

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分子的相互作用对电火花点火起决定性的作用。

Electric Spark Sensitivity of Polynitro Compounds:Part IV. A Relation to Thermal Decomposition Parameters

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.
