查询词典 breech

Type 79 submachine gun is rather unusual for its class as it is very lightweight and uses locked breech, gas operated action instead of more traditional blowback action.

79式冲锋枪是相当罕见的类，因为它是非常轻便，并使用锁膛，燃气经营的行动，而不是更多的传统的的反作用的行动。

Guns with the least 'leakage' are best, so a sealed breech (e.g. bolt action) is preferable and can be suppressed to the point that the "click" as the striker or hammer falls is the loudest sound of firing.

渗泄&最小的枪枝效果最好，所以枪膛密封的结构是最宜采用的方式，对这类枪的抑制效果能做到使射击时发出的最响的声音是击针或击锤落下时发出的&嗒声。

The principle and methodology of assembly level finite element modeling and analysis of gun breech mechanism were put forward in this paper.

该文针对火炮炮尾炮闩机构提出了对其进行装配体有限元分析的方法和建模原理。

The main reason causing the breakage of the breech mechanism has been disclosed with analysing the distribution and magnitude of the dynamic stresses in two different situations. This provides useful references for mechanism design.

通过分析机匣在两种不同情况下动态应力的分布，揭示了导致机匣破坏的主要原因，为机构设计提供了有益的参考。

The traditional practice of finite element analysis of gun components was on the basis of single part,it cannot accurately simulate the mechanics behavior of some gun components with multiple parts such as breech mechanism.

火炮构件有限元分析的传统方法是对单件进行建模分析，不能准确地对炮尾炮闩多零件装配体力学行为进行模拟。

A finite element modeling and analysis of the assembly of a breech mechanism in locking condition was carried out with special finite element techniques such as contact element, gap element and spring element.

利用接触元、间隙元和弹簧元特殊单元，对某大口径火炮的炮尾-闩体-曲臂机构进行了闭锁状态下装配体有限元建模和分析。

Combined with the 10th five -year key advanced research project of national defense "Firing technology for rifles with variable-firing-rate and double cyclic systems", the impacting dynamic stresses of this kind of rifles three key elements(breech mechanism, receiver, firing pin) are analysed and studied in this paper.

本文结合&十五&国家重点预研项目一&步枪双循环变射频发射技术研究&，对变射频步枪的三个关重件在撞击条件下的动态应力进行了分析研究。

US Navy BL guns of the period had recoild buffers and fast tarversing mechanisms - they just lacked the interrupted screw breech and fixed ammo to make them QF - or RF rapid fire as they called it.

也已经出现。美国海军在这个时期的后膛炮都拥有驻退复进机以及快速回旋机构，它们与速射炮（英国人称为Quick Fire，美国人则称之为Rapid Fire）相比只缺乏中断螺纹炮闩以及固定式弹药而已。

Every nation now has access to Breech-Loading rifles and the technology to create more advanced weaponry.

1930年，各大国均掌握了凤姐四号的生产技术，并开始着手研发更先进的武器。

On this date, the Zendar Research Academy successfully tests the first ever Breech-Loading Rifle.

这一天，禅达研究院成功试射了第一支膛装步枪。
