火药

But though towards the end of the battle the men felt all the horror of their actions, though they would have been glad to cease, some unfathomable, mysterious force still led them on, and the artillerymen—the third of them left—soaked with sweat, grimed with powder and blood, and panting with weariness, still brought the charges, loaded, aimed, and lighted the match; and the cannon balls flew as swiftly and cruelly from each side and crushed human flesh, and kept up the fearful work, which was done not at the will of men, but at the will of Him who sways men and worlds.

虽然战斗已近尾声，但人们仍感受到自己行为的恐惧；虽然他们乐于停战，但仍有一种不可思议的、神秘的力量在指导他们；虽然炮兵中三个只剩下一个，而且浑身是汗沾满了火药和血，都累得走不稳路，踉踉跄跄，气喘呼呼，但他们仍在送火药，装炮弹，安上引火线，瞄准。炮弹仍在双方间迅速而冷酷地飞来飞去，把人的身体炸成肉泥。那种不是按照人的意志而是按照统治人类和世界的上帝的旨意进行的可怕的事情，仍在继续着。

Because the pressure is a key feature of the internal ballistic inside, change curve of the pressure with time can show the circumstance of internal ballistic inside.

最主要的测量对象是压力，因为只有压力能表征内弹道的循环特性，从压力曲线可以得到火药的火药力、压力冲量及火药的燃速等重要参量。

However, I think that inmaking the experiment, we ought to employ, not the ordinary powder, thesupply of which, I think, should remain untouched, but the pyroxyle whichwill never fail us.

可是，我想还是把普通火药原封不动地留着不要用，在试验的时候用棉花火药，因为棉花火药是用不完的。

Theywere charged with pyroxyle, taking into consideration its explosive power,which, as has been said, is four times that of ordinary powder: theprojectile to be fired was cylindroconic.

前面已经说过，棉花火药的爆炸威力相当于普通火药的四倍，他们考虑到这一点，然后给大炮装上适当量的棉花火药。炮弹是圆锥筒形的。

This was a fair proposal, it must be confessed, had it been made toany one that had not had a settlement and a plantation of his ownto look after, which was in a fair way of coming to be veryconsiderable, and with a good stock upon it; but for me, that wasthus entered and established, and had nothing to do but to go on asI had begun, for three or four years more, and to have sent for theother hundred pounds from England; and who in that time, and withthat little addition, could scarce have failed of being worth threeor four thousand pounds sterling, and that increasing too - for meto think of such a voyage was the most preposterous thing that everman in such circumstances could be guilty of.

其次，我必须搞到枪枝和弹药。大舱里原来存放着两支很好的鸟枪和两支手枪，我都拿了来，又拿了几只装火药的角筒，一小包子弹和两把生锈的旧刀。我知道船上还有三桶火药，只是不知道炮手们把它们放在什么地方了。我找了半天，终于找到了。有两桶仍干燥可用，另一桶已浸水了。我就把两桶干燥的火药连同枪支一起放到木排上。这时我发现木排上装的东西已不少了，就开始动脑筋如何运上岸，因为一没帆、二没桨、三没舵，只要有点风，就会把木排打翻在海里。

Some were plugging with their ramrods, others were putting powder on the touch-pans, and getting charges out of their pouches, others were firing their guns.

有一些人正在用通条捣碎火药，有一些人正在把火药装进火枪药池里，从袋子里取出火药，还有一些人正在射击。

According to the character of the B/KNO3 fire composition,three igniters with different charging structure are comparative tested and analyzed,and aimed at the parameters of the electric igniter,calculation and design are made for the ignition charge,intermediate charge and igniter charge ring,then the charging structure of electric igniter for a certain solid rocket motor is determined.

基于B/KNO3点火药的特性，采用三种不同药型的点火具装药进行对比试验和分析，并针对电点火具的性能指标要求，分别对传火药、过渡药、点火药环进行了计算和设计，确定了适用于某固体火箭发动机用电点火具装药的药型。

Through modifying proportions of potassium nitrate, sulfur, phenolophthalein and potassium hydrate, formula of charcoal-free black powder is optimized by replacing charcoal with reactant of phenolphthalein and potassium hydrate.

以酚酞和氢氧化钾的反应物替代木炭，通过调整硝酸钾、硫磺、酚酞及氢氧化钾的混合比例对无木炭黑火药配方进行优化设计，对比研究了普通黑火药与无木炭黑火药在机械感度、静电火花感度、热分解过程及输出特性等方面的差异。

There is no set formula for this which covers all time periods, as acceptable powder charge densities, the burn rate of powders, the chemical composition of powders, the amount of the charge's energy wasted as smoke, and other factors change as improvements are made over the years.

对于这些问题在任何时代都没有什么固定的规律可循，比如适当的装药量，火药的燃烧率，火药的化学成分，由于烟气造成的能量浪费，还有其他诸如火药性能的提高之类的因素。

My next Care was for some Ammunition and Arms; there were two very good Fowling-pieces in the great Cabbin, and two Pistols, these I secur'd first, with some Powder-horns, and a small Bag of Shot, and two old rusty Swords; I knew there were three Barrels of Powder in the Ship, but knew not where our Gunner had stow'd them, but with much search I found them, two of them dry and good, the third had taken Water, those two I got to my Raft, with the Arms, and now I thought my self pretty well freighted, and began to think how I should get to Shore with them, having neither Sail, Oar, or Rudder, and the least Cap full of Wind would have overset all my Navigation.
