根据相似原理对弹丸留膛受热缩比模型的设计进行了初步的研究。在给出弹丸膛内滞留受热数学物理模型的基础上，提出了弹丸留膛缩比模型设计的约束条件，得到了相关的定性准则。根据相似条件及弹丸膛内受热机理对缩比模型的设计参量进行了讨论，得到了24个基本参量；并分析了其中部分参量的物理意义。

A primary investigation of the reduced-scale model design of the proj ectile in the heated bore was performed according to the principles of similarity theory.The constraint conditions for designing re-duced-scale model were derived and the similarity criterions were acquired based on the heat transfer model of the proj ectile in the bore.According to the similarity conditions and the heating mechanism of proj ectile in the bore,some design parameters of reduced-scale model were discussed and 24 basic parameters were obtained,then the physics meaning of some parameters were illustrated and analyzed in detail.
