本文提出了一种外渗式气阻机构的结构设想，建立了该机构的数学模型；研究了这种机构的运动特性：机构为引信提供的炮口保险距离基本了受弹速变化的影响，本文初步探讨了外渗式气阻机构在引信上使用的可能性。
In this paper, we propose a structural assumption of an infiltration-type gas-resistance mechanism and establish a mathematical model of the mechanism. The movement characteristics of the mechanism are studied: the muzzle clearance provided by the mechanism for fuze is basically affected by the change of the ballistic velocity, This article initially explored the possibility of using an infiltration type gas resistance mechanism on a fuze.
