前言大口径火炮的寿命一般决定于直膛起始段的烧蚀量。该部位烧蚀的主要原因是发射药气体的热作用与化学作用。膛内发射药气体的性质与状态是由火炮内弹道性能所决定。因此合乎逻辑的推理是:对于一定材料的身管,内弹道诸元及装药的物理、化学性质决定了大口径身管的烧蚀。但是对烧蚀的物理、化学过程至今无法作详尽地描述,内弹道诸元以怎样的
Foreword The life of large-caliber guns is generally determined by the amount of ablation at the beginning of the bore. The main reason for ablation at this site is the thermal and chemical effects of propellant gases. The nature and state of propellant gas in the chamber is determined by the internal ballistic performance of the gun. Therefore, the logical reasoning is: for a certain material barrel, the internal ballistic elements and the physical and chemical properties of the charge determines the large diameter of the ablation tube. However, the ablation of the physical and chemical processes so far can not be described in detail, what kind of internal ballistics
