弹膛

空弹膛的敲击声在门廊间回响着。

The click of an empty chamber echoed through the corridor .

弹膛后切口刮擦痕迹在认定发射枪支中的作用

Role of Scratch on the Back Slit of Chamber in Identifying Shooting Gun

末制导炮弹膛内滞留热安全模型及相似分析

Thermal safety model for terminally guided projectile in heated tube and similarity analysis

我以为弹膛已经拿出去了。

I thought the clip was out .

该文建立了自动武器抽壳计算模型，计算出抽壳时药筒与弹膛的接触压力和抽壳阻力。

This paper not only establishes a computing model of the extraction in automatic weapons , but also sets up an extraction measurement system .

分析表明初始间隙与抽壳力近似成线性负相关关系，弹膛壁厚与抽壳力近似成反比例关系，摩擦系数与抽壳力近似成线性正相关关系。

The analyses show that the initial clearance has an negative linear relation with extraction force , the bore shell thick - ness has an inverse proportion relation with extraction force and the friction coefficient has a positive linear relation with extraction force .

身管线弹膛采用径向锻造工艺一起锻出，不但能保证锻件的高精度，而且可以减少后续机械加工，还能使身管线膛与弹膛保持极高的同轴度。

When the rifling and chamber of barrel are produced at same time with the radial forging process , it does not only guarantee higher forging precision and less following machine processing , but also let the rifling and chamber of barrel maintain extremely high proper alignment .
