火炮

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。

And then I had an epiphany: we could load the gun in the shelter and take two boxes of shells with us right on the carriage, harness the horses and gallop directly out in the open in front of the German battery; immediately deploy the gun and open fire, alternating HE and fragmentation rounds.

在这时我提出：我们可以把大炮拉到掩体里准备好战斗，同时搬两个弹药箱到马车上，挽曳好之后在德军炮兵连阵地前沿的开阔地上疾驰，立即在敌军射击的爆炸和破片中展开火炮开火。

Also armed with bolters and a single torpedo launcher

还配备火炮和单一鱼雷发射器

On 12 June, during the attack on Bréville, British artillery was bombarding it when a stray shell fell short and hit a group of British officers, killing Lieutenant-Colonel A.P. Johnny Johnson (CO 12 PARA) and badly wounding Brigadiers Kindersley (CO 6 Airlanding Brigade) and Lord Lovat (CO 1st Special Service Brigade).

6月12日，受到攻击时， Bréville ，英国火炮轰击它当一个流浪炮弹落在短期和打击了一批英国军官，造成中校美联社&约翰尼&约翰逊（共12个参数）和严重伤人准将金德斯利（二氧化碳6空降旅）和主洛瓦特（二氧化碳第一特别服务旅）。

Before that, it didnt matter if you had many different calibers.

在这之前，由於接战距离过短，使用多种不同口径的火炮也没有什麼差别。

Currently the PLA has over 30,000 artillery of various types and calibres.

当前，解放军拥有30000多门各种口径、各种型号的火炮。

Artillery includes anti-aircraft and anti-tank weapons with calibres above 37 mm.

火炮包括了口径大于37mm的防空和反坦克炮

They were tested at the Kubinka proving ground by gunfire from various guns of 88 mm, 122 mm and 128 mm calibres. The results were used for developing a final scheme of armor protection.

造了两个装甲车体和两个炮塔，它们在库宾斯卡的测试场地接受了不同型号的88mm，122mm，128mm火炮地射击测试，得出的数据用来为最终的装甲防护方案提供参考。

In order to contribute to analyse and compute easily setback moving devices on the projectile fuzes,and to make the fuze devisers be able to get the approximate acceleration curves with a few parameters such as tube length and muzzle velocity of the guns,the displacement-time curve and velocity-time curve of gun interior ballistic are fitted with the Logistic models,then the formula of projectile acceleration curves in bore are gotten by the derivation of the formula of fitting velocity-time curve.

为了便于炮弹引信后坐运动机构的分析和计算，能使引信工作者只根据身管长度和炮口速度等少量参数就能获得弹丸膛内加速度近似曲线，运用Logistic函数拟合火炮内弹道的位移－时间曲线和速度－时间曲线，再对拟合得到的速度－时间曲线求导便得到了弹丸膛内加速度近似曲线。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
