坦白而言,自动方式和闭锁结构一直是枪械基础原理中的两大难点。这些结构自身非常复杂,对读者的想象力和理解力有着很高的要求。与此同时,在国内的科普工作中,又很难找到实物,无法做动态的讲解。因此,自动方式和闭锁结构就成为了既挑战讲解者、又挑战读者的“老大难”。但是,自动方式和闭锁机构又是枪械中必不可少的重要组成部分,任何与枪械相关的科普工作的重点之一。
Frankly speaking, the automatic mode and the locking structure have always been two major difficulties in the basic principle of firearms. These structures are inherently complex and have high demands on the reader’s imagination and understanding. In the meantime, it is very hard to find the kind in the science popularization work in our country and can not give a dynamic explanation. Therefore, the automatic mode and lockout structure become the “bossy challenge” that challenges both the reader and the reader. However, automatic means and locking mechanisms are also an indispensable part of firearms, one of the focuses of any science-related work relating to firearms.
