发射火药

Like the arquebus, it fires using a matchlock mechanism, a smouldering length of rope as a fuse that ignites the gunpowder in the pan.

与火绳枪类似，滑膛枪亦采用缓燃枪机构造，以缓慢燃烧的火绳点燃引药盒中火药进行发射。

Based on gas-state-equation in const-volume and propellant geometry-combustion theorem,a method for deci- ding the characteristics of deterred propellant is given.

根据定容燃烧气体状态方程和火药几何燃烧定律，推导出一种确定钝感发射药特征量的计算方法，并对某种火药进行钝感处理和计算，结果与火药切片的电扫描结果相符。

Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.

身管是火炮的关键部件，在火炮发射过程中，高温、高压的火药燃气在身管内成脉冲式高速流动，使身管受到急剧的加热，引起身管壁内的温度急剧变化，而对于带金属内衬复合材料身管，由于复合材料导热性能较差，更容易引起非均匀温度分布以及较大的温度梯度，产生不合适的变形，也会使身管的金属内衬的工作温度升高，从而使得身管的寿命降低，同时身管的发热会引起其刚度的变化，增大射弹散布。

In order to lower burning rate temperature coefficient of high energetic nitramine propellant, this thesis modifi...

为降低高能硝胺发射药燃速温度系数，对火药配方进行了优化设计。

The pressure-time curves in combustion chamber and liquid vessel are sychronously acquired.

实验采用固体火药以不同的点火压力启动再生式活塞并点燃液体发射药，同时获得了燃烧室和贮液室内 p—t 曲线。

The CRAD, launched by a 0.7g black powder charge, flies approximately 50m and airbursts at a height of some 7m, showering the target with highly lethal fragments.

以0.7克黑火药发射的近程防护弹药可飞行约50米，在约7米高度空爆，以高毁伤破片雨的样式射向目标。

They seldom, or even never, came systematically to the firearm literature of the Ming Dynasty, such as the prescription technology of the firing charge and multi-composition gunpowder.

但对某个时期的火器文献进行深入讨论则较少，而对明代火器文献进行系统的研究，诸如发射火药与多成分火药配方工艺几无涉及甚至是完全空白。

In the Ming Dynasty published many monographs and monumental works, which, as a component of our traditional military culture and the fruit of the development of firearms technology, are characterized in gunpowder prescription technology including compatibility principles of gunpowder, prescriptions of the firing charge and multi-composition gunpowder, and ballistic hit technology, mainly about scientific design and manufacturing of blunderbusses, the ranges in various angles of depression and elevation, the standards of range and factors which have influence the range.

它作为我国传统军事文化的一个组成部分，火器技术发展的结晶，尤在火药配方技术、弹道命中技术上多独具自己的特色。火药配方技术主要有火药配伍原则、发射火药配方和多成分火药配方；火器弹道命中技术主要有科学设计与制造铳炮、不同俯仰角的射程、射程量度标准及影响射程的因素等。

The result shows that the movement of the propellant grains is complex and relative to the ignition system very much. Guns with center tube ignition and flame-spreading system can alleviate the accumulation of the propellant effectively, and will have better performance.

结果分析表明：火炮点火后膛内火药颗粒的运动情况十分复杂，其运动规律与点传火的方式密切相关，点火孔均匀分布的中心传火管点火方式可以有效的改善发射过程中火药颗粒在弹丸底部堆积的现象，获得更佳的发射效果。

Then the major rule of different structure parameters" effects on weapon performance are found, which can provide theoretical basis for the further design of the weapon.An innovative principle concept for "Canister Rifle hitched on the Gun is put forward based on the analysis of the above three concepts.

在对三种方案分析的基础上，本文还提出了一种具有较大创新的枪挂霰弹发射器的原理方案，该方案能够更进一步提高火药气体的能量利用效率和枪挂霰弹发射器的威力。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
