火炮

For precision azimuth, as in gunfire control, a double-lobe pattern (figure 3) can give great directional precision by finding the direction in which the echo "pips" for both lobes are of equal heights. This is called "lobing".

当需要精确的方位角，如指挥火炮时采用双波瓣发射，两波瓣回迹强度相等时便可获得精确的目标方位角，这被成为&波瓣法&。

From April of 1942, 20mm spaced armor was added to the gun mantlet and/or superstructure front.

从1942年4月，在其火炮护盾和/或上部结构的前部加挂20mm附加装甲。

Later variants had a rotating periscope for the driver, a new exhaust arrangement, a new mantlet design to eliminate the shot trap and a new engine deck layout with a raised fan cover.

后期的变化是有一个供驾驶员使用的可旋转的潜望镜，一个新的废气管的排列方式。和设计了一个新的火炮护盾去防止射击时候的损伤。

From August of 1940 until 1942, all Ausf E tanks were rearmed with 50mm KwK 38 L/42 gun mounted in an external mantlet housing one MG.

从1940年8月到1942年，所有的E型坦克换装50mm KwK 38 L/42 火炮，in an external mantlet housing one MG。

Modifications included the addition of three wooden logs to both sides of the superstructure, armor around the gun mantlet was reinforced with concrete, tracks were mounted on the lower front hull and both sides of the hull along with stowage bins.

改进措施包括，在车体的两侧增加了三根原木，火炮防盾周围的装甲用水泥加固，车体首下装甲安置了备用履带，车体的两侧增加一个大型储物箱。

For naturally cooled monobloc barrel, its thermal condition in regular regime can be evaluated by measuring the outside temperature of two arbitrary rounds;(2) During a sustained firing process, unsteady heat conduction exists in a monobloc barrel, whereas unsteady and quasi steady heat conduction exist with actively cooled composite barrels, meaning that the thermal condition changes from uncontrolled to controlled;(3) Different combinations of the convective heat transfer coefficient h and thickness of gun barrel δ have much effects on cooling the bore temperature.

利用有限元软件分析了某大口径火炮身管的温度场分布，并对自然散热条件下的单筒身管和主动冷却条件下的复合身管温度场进行了比较，其结果为(1)身管温度场分布存在初始和正规工况阶段，后者的单筒身管热状态可以通过测定任意两发身管外表面温度来评估；(2)持续射击过程中，单筒身管始终处于非稳态导热过程，主动冷却身管则包括非稳态和准稳态两个过程，实现了身管热状态由不可控向可控转变；(3)对流传热系数h和身管壁厚δ的组合对降低内膛温度具有很大影响。

The ballistic performance of coated nitramine propellant on 105mm gun was studied and apparent low temperature coefficient result was obtained.

研究了硝胺发射药的低温感技术，获得了明显的效果，并在105mm火炮上得到验证。

In this thesis, the principle that the charge technique of coated nitramine and energy increased propellant with low temperature sensitivity improves the muzzle velocity and decreases ballistic temperature coefficient is studied.

本文研究了低温感硝胺及增能发射药装药技术提高火炮初速和降低弹道温度系数的原理及其对膛压和初速变化规律的影响，阐述了提高低温感。。。

Accroding to the principle of low temperature sensitivity charge, the application test of LTSC of nitramine propellant in the large middle caliber gun was analysed.

从低温感发射药的基本原理出发，对低温感硝胺发射药在中大口径火炮上的应用试验进行了分析研究。

The test and verify to model and its'computer program was done by calculating the ballistic effect of coated nitramine and nitroguanidine propellants on 105mm gun.

通过105mm火炮硝基胍和硝胺两种低温感装药的计算，对模型及其计算程序进行了验证，其计算值与实测值相吻合，表明模型具有实用价值。

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。
