(8)火药英语作文扩展阅读：

烟花起源：

相传在隋末唐初，著名炼丹家、医药家孙思邈，为了专意炼丹和行医，隐栖在浏阳县城东门外的一个岩洞内。他将采挖而来的硫磺、加上硝石和木炭等物料，装入丹炉，日夜炼制。历经寒暑和屡次的失败，终于炼制出了火药。

至此，他真正成为了浏阳的鞭炮烟花乃至全世界的鞭炮烟花的奠基者。后人为了纪念他，将他隐居的岩洞称为孙隐崖，炼丹的地方称为炼丹台，洗药的井和泉分别称作洗药井和洗药泉，至今保存完好。

到了唐太宗贞观年间，湘东连年旱涝大灾，民不聊生。这时，一个叫李畋的浏阳人，决心驱赶邪恶。他将竹筒填满火药，安上药线，点燃后响声宏大，清香四溢，邪瘴终于被驱赶而去，人们得以安居乐业，天下太平。

从此，浏阳鞭炮烟花便诞生了。浏阳人李畋被尊称为鞭炮烟花的“祖师爷”。南宋时，在浏阳县城的田家巷，人们修建了一座祖师庙，以纪念李畋的功绩。现浏阳的麻石小街田家巷，尚存宋代所建的“祖师庙”，供奉着鞭炮业的“祖师”——李畋。

早在清朝嘉庆初年，浏阳的大瑶、金刚、澄潭江、文家市、杨花一带，有近90％的农户从事花炮生产，素有“十家九爆”之美誉，年产逾14万箱，咸丰五年已有出口，同治十一年形成了大行业，最高年产已近25万箱。花炮生产技术也处于当时社会的领先地位。

雍正登基时，为改元正朔，要在元年元宵佳节燃放响炮、烟花，传旨编炮行业，要创新花上京。其时浏阳官吏诚惶诚恐，四处张贴告示，广纳良才，并指令编炮能手李泰限期创出新花进贡，致使李泰寝食不安。

一日，他路过铁匠铺，见锤下星火四射，有长有短，有红有白，有粗有细，有料有丝，心有所动。随后李泰扫了一些铁屑，回到家中把其锤得粉碎，再掺以火药和米汤一起搅和。

铁砂、火药拌和得大小粗细不等，再以黑硝作动力，装于底部导火线处，于是，便造出了喷射出花色形态各异，或梅或菊等多姿多彩的花朵来。待李泰的新花在紫禁城上空高升钻天，落下缤纷的花雨，把雍正直看得眼花缭乱、目不暇接。从此，浏阳便享有了花炮之乡的盛名。

三四十年代，做花炮有名的，首推浏阳的李四美花炮坊。李四美作坊为商人李熙雅所创建，他恢复发展了行祖失传的技艺，初从铁屑成末掺入原料，制成焰火“萝卜花”后又以洋生铁屑和以多种药物，先后制出大叶兰花、大叶菊花、二梅花和连升三级等烟花。

1918年作坊取名为“李四美”，相继制作出地老鼠、天鹅抱蛋、二龙戏珠、滴滴金等玩具型烟花。后又研制出大型组合烟花，燃放时，花木鸟兽和各类人物逐层腾空，蔚为壮观。故当时以“李四美”作坊命名的浏阳烟花开始在国内外享有声誉。

㈨ 介绍火药的火药英语作文

Gunpowder 火药
Handgun from the Yuan dynasty, circa 1300s.
The prevailing academic consensus is that gunpowder was discovered in the 9th century by Chinese alchemists searching for an elixir of immortality. By the time the Song Dynasty treatise, Wujing Zongyao was written by Zeng Gongliang and Yang Weide in AD 1044, the various Chinese formulas for gunpowder held levels of nitrate in the range of 27% to 50%. By the end of the 12th century, Chinese formulas of gunpowder had a level of nitrate capable of bursting through cast iron metal containers, in the form of the earliest hollow, gunpowder-filled grenade bombs.
In AD 1280, the bomb store of the large gunpowder arsenal at Weiyang accidentally caught fire, which proced such a massive explosion that a team of Chinese inspectors at the site a week later deced that some 100 guards had been killed instantly, with wooden beams and pillars blown sky high and landing at a distance of over 10 li (~2 mi. or ~3.2 km) away from the explosion.
By the time of Jiao Yu and his Huolongjing in the mid 14th century, the explosive potential of gunpowder was perfected, as the level of nitrate in gunpowder formulas had risen to a range of 12% to 91%, with at least 6 different formulas in use that are considered to have maximum explosive potential for gunpowder. By that time, the Chinese had discovered how to create explosive cannonballs by packing their hollow shells with this nitrate-enhanced gunpowder.

㈩ 火药的英文简介

Gunpowder, also called black powder, is an explosive mixture of sulfur, charcoal and potassium nitrate, KNO3 (also known as saltpetre/saltpeter) that burns rapidly, procing volumes of hot solids and gases which can be used as a propellant in firearms and as a pyrotechnic composition in fireworks. The term gunpowder is also often used more broadly to describe any propellant powder used in firearms. Modern firearms do not use the traditional gunpowder (black powder) described in this article, but instead use smokeless powder. In this article, the terms gunpowder and black powder are used interchangeably.

Gunpowder is classified as a low explosive because of its slow decomposition rate and consequently low brisance. Low explosives proce a subsonic deflagration wave rather than the supersonic detonation wave proced by brisants, or high explosives. The gases proced by burning gunpowder generate enough pressure to propel a bullet, but not enough to destroy the barrel of a firearm. This makes gunpowder less suitable for shattering rock or fortifications, where high explosives such as TNT are preferred.

The term "black powder" was coined in the late 19th century to distinguish prior gunpowder formulations from the new smokeless powders and semi-smokeless powders. (Semi-smokeless powders featured bulk volume properties that approximated black powder in terms of chamber pressure when used in firearms, but had significantly reced amounts of smoke and combustion procts; they ranged in color from brownish tan to yellow to white. Most of the bulk semi-smokeless powders ceased to be manufactured in the 1920s.)[1][2][3]

Black powder is a granular mixture of

a nitrate— potassium nitrate (KNO3)—which supplies oxygen for the reaction;
charcoal, which provides fuel for the reaction in the form of carbon (C);
sulfur (S), which, while also a fuel, lowers the temperature of ignition and increases the speed of combustion.
Potassium nitrate is the most important ingredient in terms of both bulk and function because the combustion process releases oxygen from the potassium nitrate, promoting the rapid burning of the other ingredients.[4] To rece the likelihood of accidental ignition by static electricity, the granules of modern black powder are typically coated with graphite, which prevents the build-up of electrostatic charge.

The current standard composition for black powder manufactured by pyrotechnicians was adopted as long ago as 1780. It is 75% potassium nitrate, 15% softwood charcoal, and 10% sulfur.[5] These ratios have varied over the centuries and by country, and can be altered somewhat depending on the purpose of the powder. For instance, coarser grades of black powder, unsuitable for use in firearms but adequate for blasting rock in quarrying operations, is called blasting powder rather than gun powder; it is often made with the cheaper sodium nitrate substituted for potassium nitrate in proportions of 60% nitrate, 20% charcoal and 20% sulfur.[citation needed]

The burn rate of black powder can be changed by corning. Corning first compresses the fine black powder meal into blocks with a fixed density (1.7 g/cm³). The blocks are then broken up into granules. These granules are then sorted by size to give the various grades of black powder. In the United States, standard grades of black powder run from the coarse Fg grade used in large bore rifles and small cannons, through FFg (medium and smallbore arms such as muskets and fusils), FFFg (smallbore rifles and pistols), and FFFFg (extreme small bore, short pistols and most commonly for priming flintlocks). In the United Kingdom, the gunpowder grains are categorised by mesh size: the BSS sieve mesh size, being the smallest mesh size on which no grains were retained. Recognised grain sizes are Gunpowder 'G 7', 'G 20', 'G 40', and 'G 90'.
