从数量级分析看含能材料的临界热能密度

STUDY ON CRITICAL THERMAL ENERGY DENSITY FOR ENERGETIC MATERIALS BY MAGNITUDE ORDER ANALYSIS

从能量角度用数量级估计的方法分析数种重要的感度试验数据，提出临界热能密度的概念。对几种公认的冲击作用下热点形成机理，估计其吸收的热能密度能否达到临界值。从化学分解动力学的角度分析临界热能密度的本质。

Data on several important sensitivity tests are analyzed again by a method of magnitude order estimation,then a concept on the critical thermal energy density is formulated.It is estimated whether thermal energy densities absorbed to its threshold for generally recognized mechanism of shock induced hot spot formation.Its essence is probed into by chemical kinetics.It is considered that the critical thermal energy density may be the characteristic parameter for energetic material ignition.
