火药

Another Trick I try'd upon him, which he innocently came into also; his Name was Ismael, who they call Muly or Moely, so I call'd to him, Moely said I, our Patroon's Guns are on board the Boat, can you not get a little Powder and Shot, it may be we may kill some Alcamies for our selves, for I know he keeps the Gunners Stores in the Ship?

接着我又想出了一个新花样，他居然天真地上了圈套。这个摩尔人的名字叫伊斯玛，但大家叫他马利或莫利，所以我也这样叫他。"莫利，"我说，"我们主人的枪在船上，你去搞点火药和鸟枪弹来，也许我们还能给自己打几只水鸟呢！我知道主人的火药放在大船上。"

He built two huts with pimento trees, covered them with long grass, and lined them with the skins of goats, which he killed with his own gun as he wanted, so long as the powder lasted, which was but a pound; and that being almost spent he got fire by rubbing two sticks of pimento wood together upon his knee...

他用甘椒树给自己搭了两个小屋，并用茅草做屋顶，屋顶的边沿是他用火枪打到的山羊的皮做的。在他需要的时候，他会用火枪去打些山羊，但能供他使用的火药也只有一磅的样子，用完了也就没有了。火药现在已经用得差不多了，他只好用两根甘椒树的树枝在自己膝盖的摩擦，打出火来。

Though there was no powder in it; but about two pound of fine glaz'd powder, in three small flask s, kept, I suppose, for charging their fowling-pieces on occasion

箱子里没有很多火药，只有两磅压成细粒的火药，装在三只小瓶里；我想大概是装鸟枪用的。

They poured in gunpowder.Then,with a stick called a ramrod,they pushed a round bullet into the rifle,until it was against the gunpowder.

他们先把火药倒进去，然后用一根叫做"通条"的棍子把一颗圆形子弹填进步枪里，把子弹紧紧地与火药捣实。

It was pointed out that the diameter of the powder core of safety fuse was themain factor for its combustibility by a discussion of the combustion mechanism of the black powder, and the on-line testing significance of the diameter of the powder core was also described inthis paper.

With saltpeter, sulfur and charcoal made from these three kinds of material mixed, but when people have these three kinds of things as the treatment of drug, so the name "gunpowder", meaning "fire medicine."

火药 用硝石、硫黄和木碳这三种物质混和制成的，而当时人们都把这三种东西作为治病的药物，所以取名"火药"，意思是"着火的药"。

Powder is mainly used by saltpeter, sulfur and charcoal made from mixing these three substances, the beginning of the Tang Dynasty, mainly for military gunpowder.

火药主要是用用硝石、硫黄和木炭这三种物质混和制成的，唐朝开始，火药主要用于军事上。

Incurrent research, aiming at the rupture problem engendered in the shooting process of acertain 5.56mm automatic rifle, the strain and stress distributions on the cartridge caseunder the action of axial pull have been analyzed. Based on the theories of elastic-plasticmechanics and contact mechanics, a mathematic and physical model of the cartridge-caseand chamber system has been set up; and based on the platform of the general softwarepackage APDL of ANSYS for finite element analysis, a parameterized model of thecartridge-case and chamber system has also been established. The method for nonlinearFEA has been adopted to analyze the stress distribution on the entire cartridge-case andchamber system, and the method of contact element has been employed to investigate thecontact stress between the cartridge case and chamber, and then the influences of frictioncoefficient and locking space on the static and dynamic stress and strain response of thecartridge case and chamber to the action of power gas have also been discussed. On thebasis of a lot of numerical tests, a kind of element Plane13, which is concentrated incoupled computation of heat and construction, has been used finally to simulate thetransient response of the cartridge-case and chamber system to the power gas. Throughloading the temporary thermal characteristics of explosive gas in the procedure of emulate, the corresponding transient thermal stress distributed on the entire system under thecombined load of transient thermal stress and transient pressure has been obtained. Owingto these comprehensive considerations, the numerical results obtained in this paperrepresent the actual situations comparatively exactly.
