炮身

With this model analytical solutions for differential equations of the projectile's motion within an ideal bore can be obtained. Comptations for some projectile...

求得了对称弹丸在理想身管中的运动微分方程的解析解，并对某些弹炮系统进行了计算，得出了一些有用的结论。

Admiral Roebuck turned to his fellow officers and asked,"You saw that radar controlled Gatling gun, General?"

罗巴克上将转过身问他的同伴们："诸位，你们是否看见了由雷达控制的加特林炮？"

Based on interior ballistic theory, an attempt has been made to study the initial variable bullet dispersion of Gatling gun with a basic mathematical analysis model of bullet movement.

针对转管炮发射时身管处于旋转状态的特性，建立了同时考虑弹丸旋转惯性力和科氏力的半约束期内起始模型，分析了惯性力、科氏力在半约束期内对弹丸起始扰动的影响，计算得到了在半约束期运动弹丸的偏角变化规律。

That was a fully redesigned Rheinmetall 37 mm AT-gun Pak 30 with a longer barrel and higher muzzle velocity.

它完全是在德国Rheinmetall公司的Pak-30型37mm炮的基础上重新设计而成，拥有一个长身管和高炮口初速。

The last gasp came as Johnny Damon homered to lead off the ninth and, after an out, Mark Teixeira singled through the left side to chase Lannan and bring on Mike MacDougal. Representing the tying run, pinch-runner Brett Gardner swiped second base on a pitchout and took third base on an offering in the dirt.

Y 最后一博的希望，是发生在九局下首名打者强尼戴蒙轰出阳春炮时，然后经过一个出局数，铁爷敲了一支左向的一垒安打，迫使拉男下台一鞠躬，换上后援投手Mike MacDougal，这时，身兼追平分希望的代跑者贾得纳利用一记暴投盗上二垒，又靠一颗地瓜球冲上三垒。

A supremely powerful warship. Sporting heavy cannon broadsides and a thick hull. Can travel across the ocean.

卡拉克巨舰是庞大的精锐战舰，配备大口径舷炮和坚固舰身，能进行远洋作战。

It had jackknifed into a ditch and had to be abandoned by its crew.

大炮身管弯曲，扎在一道壕沟里，已被炮组丢弃。

Simulated the backlash process of cannon barrel, advanced a new algorithm for the computation of muzzle brake efficiency.

本文用数值计算的方法模拟火炮身管自由后坐过程，给出了一种新的炮口制退器效率计算方法。

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。

Meanwhile Nesvitsky, Zherkov, and the officer of the suite were standing together out of range of the enemy, watching the little group of men in yellow shakoes, dark-green jackets, embroidered with frogs, and blue riding-breeches, swarming about the bridge, and on the other side of the river the blue tunics and the groups with horses, that might so easily be taken for guns, approaching in the distance.

其时，涅斯维茨基、热尔科夫和侍从军官一同站在射程以外的地方，时而观看这群正在桥头蠕蠕而动的官兵，他们头戴黄色的高筒军帽、身穿绣有绦带的暗绿色上装和蓝色的紧腿马裤，时而观看远处慢慢地移近的身穿蓝色外套的法国兵和骑马的人群――很容易认出那是炮队。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
