火药的种类和分类

写作思路：罗列出中国的四大发明，写出这些发明的伟大之处，使用简单的英文句子描写出这些。

正文：

There are four world famous inventions in China, one is gunpowder, the other is compass, the third is printing and the fourth is papermaking.

我国有世界著名的四大发明，一是火药，二是指南针，三是印刷术，四是造纸术。

This makes our ancient China become an ancient civilization.

这让我们中国古代成了文明古国。

China's four great inventions have played an irreplaceable role in various fields of science and technology.

中国的四大发明在各个科技领域中起到了不可替代的重要作用。

Gunpowder. Gunpowder was invented by us.

火药，火药是我们发明的。

火药英语怎么说

gunpowder。火药，又被称为黑火药，是由硝酸钾、木炭和硫磺机械混合而成。在适当的外界能量作用下，自身能进行迅速而有规律的燃烧，同时生成大量高温燃气的物质。

火药在军事上主要用作枪弹、炮弹的发射药和火箭、导弹的推进剂及其他驱动装置的能源，是弹药的重要组成部分。火药是中国四大发明之一，以其杀伤力和震慑力带给人类消停战事、安全防卫的作用，是人类文明的一项重要发明。

注意事项：

中国古代发明的火药，是将三种原材料捣碎后碾成粉末，经过拌和配制成混合火药。而现代火药的原料则有很多，比如，苦味酸、氯酸钾、硝化甘油等。火药指的是由火花、火焰等引起剧烈燃烧的药剂，其在军事上应用比较多，主要是作枪弹、炮弹的发射药和火箭、导弹的推进剂及其他驱动装置的能源。

火药英文翻译

Gunpowder, also called black powder, is an explosive mixture of sulfur, charcoal and potassium nitrate, KNO3 (also known as saltpetre/saltpeter) that burns rapidly, producing 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 produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The gases produced 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 reduced amounts of smoke and combustion products; 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—typically 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 reduce 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'.

火药的化学名称叫什么

Gunpowder,also known since the late 19th century as black powder,was the first chemical explosive and the only one known until the mid-1800s.

It is a mixture of sulfur,charcoal,and potassium nitrate (saltpeter)—with the sulfur and charcoal acting as fuels,while the saltpetre works as an oxidizer.Because of its burning properties and the amount of heat and gas volume that it generates,gunpowder has been widely used as a propellant in firearms and as apyrotechnic composition in fireworks.

火药的原理及应用

Gunpowder was invented by the Chinese people, it has been one thousand years ago. The research began from the ancient alchemy gunpowder

The Tang Dynasty alchemists in Karata Muneyongjun first year (682 years) pioneered the sulfur volt fire method, with sulfur, saltpeter, and research into a powder, coupled with the soap slot (containing carbon). Tang Xian Zong Yuan and three years (808 years) and a fire like Cephas, with saltpeter, sulfur and aristolochic (containing carbon) with firing. These two formulations, are the three kinds of spices mixed together, we have the ingredients of gunpowder. The invention of the country has been more than one thousand years ago. The research began from the ancient alchemy gunpowder.

以上就是火药的详细介绍英语的全部内容，火药英语是gunpowder 1.火药介绍 火药，顾名思义，可由火花、火焰等引起剧烈燃烧的药剂。据《范子计然》的记载，春秋时代中国就已经用于民间民生应用，范子计然说“硝石出陇道”。火药是中国四大发明之一。是在适当的外界能量作用下，自身能进行迅速而有规律的燃烧，同时生成大量高温燃气的物质。内容来源于互联网，信息真伪需自行辨别。如有侵权请联系删除。
