摘要

以含氢、碳、氮、氧的14种主要炸药为例，证明了冲击敏感性与自燃临界温度Tcr有关，而自燃临界温度Tcr又由分解反应的动力学参数和热决定。同时，反应速率是主要因素，在此背景下，化合物的热物理性质和比摩擦系数对灵敏度的影响几乎不明显。

Relationship of the Impact Sensitivity of Explosives with the Thermal Decomposition Reaction

By the example of 14 compounds representing the main classes of explosives containing H, C, N, and O, it has been shown that the impact sensitivity correlates with the critical temperature T_cr of spontaneous ignition, which, in turn, is determined by the kinetic parameters and heat of the decomposition reaction. At the same time, the reaction rate is the dominant factor, and against its background the effect produced on the sensitivity by the thermophysical properties of the compounds and by the specific coefficient of friction becomes barely noticeable.

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
