查询词典 arch barrel

Basically, you want to mount the bottom barrel on its legs (and we recommend connecting these to a couple of two-by-fours for a sturdier base), and then mount the fire door to it, followed by the connecting supports and the two flues (remember to insert the dampers before you bolt on the top barrel).

基本上，你想挂载的底部桶，其腿（我们建议连接这些一对夫妇的两个由4一个坚强的基地），然后装入防火门给它，其次是连接支持和2火道（请记住插入阻尼器之前，您对螺栓顶端桶）。

The M249 is gas-operated and air-cooled. It has a quick-change barrel, allowing the gunner to rapidly replace an overheated or jammed barrel. A folding bipod is attached near the front of the gun, though a M192 LGM tripod is also available. It can be fed from both linked ammunition and STANAG magazines, like those used in the M16 and M4. This allows the SAW gunner to use rifleman's magazines as an emergency source of ammunition in the event that he runs out of linked rounds. However, this will often cause malfunctions because the magazine spring has difficulty feeding rounds quickly enough to match the SAW's high cyclic rate.

M249采用气动、风冷原理，枪管可快速更换令机枪手在枪管故障或过热时无须浪费时间修理，机枪下前方装有折叠式两脚架，也可使用M192轻机枪的三脚架。M249采用弹链及STANAG弹匣双重供弹，机枪手在断链缺乏弹药等紧急情况时可向装备M16或M4步枪的步兵借用弹匣来射击，但以弹匣供弹时会因弹匣弹簧弹力太大而射速过高及可能出现故障。

Its include: barrel, set up in the barrel components of the screw, fuel tanks, motor oil, the radio front plate, Radio Taiwan after the board and guide column, referred to the radio through the bottom of the front plate connected to the guide block guide Column, referred to Taiwan after the radio connected to the rod on the board.

其包括：机筒，设置在机筒元件中的螺杆，油缸、油马达、射台前板、射台后板、引导柱，所述的射台前板通过下端的引导块连接在引导柱上，所述的射台后板连接在活塞杆上。

Aimed at some problems that radial wear quantity measuring accuracy of gun barrel inner bore was low,and the degree of automation was not high,by use of laser un-touched measuring technology,a precision measuring system of gun barrel inner diameter was designed.

针对现有火炮身管内膛径向磨损量检测仪器所存在的测量精度低、自动化程度不高等问题，设计了一套利用激光非接触测量技术对身管内径实现精密测量的系统。

The forms of fatigue cracks in bore of gun barrel are considered as edge cracks and semi-elliptical cracks. The stress intensity factors of gun barrel are calculated using a weight function method under the autofrettaged residual stress, thermal stress and assemblage stress.

3武器身管内表面的疲劳裂纹考虑为边裂纹和半椭圆型表面裂纹两种形式，用权函数方法研究了身管在自紧残余应力、温度应力和装配应力作用下的应力强度因子。

Based on gun bore radial wear Δdmax as discrimination condition of barrel life the mathematical model for predicting melt-erosion of gun-barrel is established which is employed in analyzing factors affecting the life of gun such as material, gun powder,firing conditions and so on. It is pointed out that active cooling technology is an effective method for solving many problems concerned with heat transfer each time the gun is fired.

文中由身管寿命判别条件△d_建立了身管熔化烧蚀预测计算模型，从原理上对各种延缓烧蚀速度、提高身管寿命的措施，如采用内膛镀铬、使用冷火药和护膛剂等进行了阐述；同时基于该模型指出采用身管主动冷却技术是延长火炮身管寿命最有效的措施之一。

Xu: I think Mao Zedong,"the regime inside the barrel of a gun", which is his approach, but you will party the Chinese Democratic Party in this way of peace is also a kind of complaint, but should be combined with China's national conditions, I can not that must be "inside the barrel of a gun out of power" should combine the two sides.

徐祥：我认为毛泽东讲&枪杆子里面出政权&，这是他的一种做法，但是你们中国民主党会党用这种和平申诉的方式也是一种方式，但要结合中国国情，我也不能说一定要&枪杆子里面出政权&，应双方面相结合。

这几乎和全世界最好的产酒地区勃艮第的做法--橡木桶发酵法相同。

By employing a certain kind of rapid-fire-gun barrel adopting outside liquid cooling method to act as the research object, the fluid-structure coupling heat-transfer model of barrel, cooling fluid and water-jacket was established, and then such a model was calculated with finite element method.

以某采用外液冷方式的速射火炮身管为研究对象，建立了包括身管、冷却液和水套的流固耦合传热模型，使用有限元方法进行研究。

You can do some assertiveness training.

你可以进行一些自信训练。
