Does anyone know how much gunpowder is consumed by firecrackers in China every year? Convert to TNT equivalent. Let's do the math!
The annual output value of China's fireworks is more than 10 billion yuan, less than 20 billion yuan, and domestic sales are 5 billion yuan. According to the industry's internal calculations, high-end firecrackers (such as high-altitude fireworks) are about 50 yuan a kilogram of gross weight (the ex-factory price is so low, the industry has high profits, cats are greasy, and the draft is deep), ordinary firecrackers are 10 yuan a kilogram of gross weight, and each kilogram of gross weight can be converted to TNT equivalent kilograms to kilograms on average.
Therefore, it is estimated that the equivalent TNT equivalent is in the mass and quantity range of 10 million kilograms to 1 million kilograms.
For details, please refer to; "Simplified Production Method for Explosives" Zhang Deyao Beijing: National Defense Industry Press, 965, 215 pages, light green cover.
Ask for fireworks composed of special symbols Hurry!
Chief of Reporting: Truthfully report the following ---
Now there are several schemes for the fireworks that produce patterns;
The most old-fashioned is the gunpowder array fixed to the ground, which is ignited together or pre-programmed, and ignited at intervals, which can be understood by children.
Either there is a three-dimensional cavity made of paper paste in the bullet body, which is laid out according to the pattern you need, which is the process of customization according to customer requirements, there are bonding and rolling gunpowder balls in the cavity, and the fireworks are ignited after they are lifted into the air, and the burning and glowing gunpowder balls can form a simple pattern in space, priced at 1000 yuan to 3000 yuan a piece, and the production cost is less than 500 yuan a piece.
Now they are all learning from the practice of foreign countries ten years ago, using programmable electronic delay fuzes, because there are many manufacturers of imitation, they have long used the original special chip, and the general single-chip microcomputer is used, and the cost of the fuze part starts from 10 yuan; The pointing of each launch tube at a fixed interval on the ground must be tested, which is the dot matrix method of the fireworks of the Beijing Olympics and the Tiananmen Square fireworks of the 60th anniversary of the founding of the People's Republic of China. The standard of this barrel array and the ground-programmed launch computer** are more than one million yuan each. For ordinary customers, a rough system with 20,000 yuan can be opened.
The minimum consumption of a word is 20,000 yuan, and the reserve price is also public, an integrated circuit controls timed fireworks from 100 yuan to 1,000 yuan, and it is 10,000 yuan to hit ten points, and it is the concession to produce fireworks, transport fireworks, store fireworks, and launch fireworks. Big customers are not just typing a few words, there are still supporting service projects.
As for the pattern generation method of the next generation of fireworks, it is a new system, because the Guangzhou Asian Games Organizing Committee has kept technical documents, there is a confidentiality agreement, it is not suitable to be public, there is no precedent in the world, and you can't find the relevant news, and you can't search for the slightest bit of content.

One of the most memorable things about the Spring Festival is setting off firecrackers on Chinese New Year's Eve, what about you?
It's Chinese New Year! It's Chinese New Year! Relatives and friends all go to grandma's house for the New Year, and everyone knows that dumplings must be eaten during the Spring Festival, so everyone has to make dumplings in the evening.
At noon, I saw my grandmother, my mother, and my relatives and friends all chopping meat in the kitchen, making dumplings with dough and wrapping dumplings. I saw that everyone was tired, so I went into the kitchen and decided to help them make dumplings together.
I took a piece of mom and good noodles, rushed into dumpling skin, used a spoon to dig a little dumpling filling and put it on the dumpling skin, and then I followed my mother's dumpling style, pinching the dumplings, but I can't pinch it well, I can only pinch it into a round like a dumpling ball, my mother saw me making dumplings and said how the shape of your dumplings is round, my mother saw that I couldn't wrap it, my mother slowly taught me, and after a while I finally learned.
We kept wrapping until we finished wrapping the dumplings, and in the end the shape of the dumplings was still different for everyone, it still looked like a circle, but I tried my best.
But after a while, our dumplings have a purpose, we put the pot on the fire, fill it with water, wait until the water boils, then put the dumplings into the pot, we sit in the restaurant and wait for a while, the dumplings are cooked, my mother brings the dumplings, we eat with relish, because this is our own dumplings.
Although I don't wrap it very well, this is my dumpling, and it condenses my hard work.
Chew it, don't mention how delicious this bowl of dumplings is!
The Spring Festival is like a cup of strong wine, which makes my heart drunk all of a sudden, and it makes me experience the happiness of childhood during that time.
The happiest thing for me during the Spring Festival is making dumplings and eating dumplings. At first, I didn't know how to make dumplings, but I sincerely said to my mother, "Mom, I want to make dumplings."
Mom said, "I'll wash your hands and teach you how to wrap them." So I quickly washed my hands, and hurriedly ran to my mother's side, and saw that my mother had rolled the skin first, and then put the suitable filling in the skin, and then my mother pinched it side by side, left and right.
Then put the left and right corners of the dumpling skin in a nest and press it hard, so that the dumplings are ready. I learned from my mother's method and wrapped one, but it was different from my mother's shed, it was a mess, and the filling was still peeking out of the skin. Under the patient guidance of my mother, I wrapped another one, and I had confidence in Lijing and lead carving.
By the third time, my bag was even better. Mom said vigorously: The bag is good, so it's like this.
After listening to my mother's words, I became more confident, and I continued to make more than a dozen dumplings, and when I finished wrapping, my mother cooked the dumplings and served them on the table, which was really fragrant. Eating my own dumplings, I am happier. I felt more fragrant than eating my mother's dumplings, and at the same time, I also felt a sense of accomplishment.
The Spring Festival gave me happiness and brightness. I learned how to make dumplings during the Spring Festival, and I also learned that labor brings happiness, and this happiness records my growth.

Chinese New Year is the most important and happiest festival of the year. The various special activities during the Chinese New Year make the Spring Festival full of festive and joyful atmosphere, and also leave us with unforgettable memories. ......Specifically, this year's Spring Festival memorable things include catching up with the big collection of New Year goods, small New Year festival stoves, and making dumplings and sticking couplets to eat Chinese New Year's Eve dinner.
1. Rushing to do New Year's goods, stopping Zheng is the most ceremonial experience during the Spring Festival.
In my experience of this year's Spring Festival, the most ceremonial content is to catch up with the New Year's goods......Unlike going to a shopping mall or supermarket, the big market is usually held outdoors in a wide field. Although the conditions are not as good as those in shopping malls and supermarkets, they give people the feeling of full of life. In my own memory, only the New Year's goods that catch up with the big collection are the most authentic, and the New Year is the most flavorful.
This habit has been maintained to this day, every time before the Chinese New Year, I have to go to the rural market to do New Year's goods, let myself experience the unique flavor of the year, so that this spring Jane Song Festival is full of rituals. This is also the most unforgettable experience I lost during this year's Chinese New Year.
2, the twenty-third day of the lunar month, the small year, the sacrificial stove, this experience is also unforgettable.
The twenty-third year of the lunar month is a small year. Since it is also a year , it is very important. ......There is a very important thing on this day, and that is the sacrificial stove.
Although it is not clear to me how to sacrifice the stove, the sense of ritual in this event itself is far more important than the thing itself. In my impression, only after the New Year's sacrifice stove, the Spring Festival full of rituals really began. Because of this, I have a deep memory of this experience and will never forget it for a long time.
3. Making dumplings, pasting couplets, eating Chinese New Year's Eve, and keeping the New Year during the New Year are my most unforgettable experiences.
If it is said. What is the most ceremonial thing during the New Year, that is, on the day of the Chinese New Year's Eve, the family reunites to make dumplings, paste couplets, eat Chinese New Year's Eve dinner and observe the New Year. ......On this day, the whole family takes action, making dumplings and preparing various delicacies while sticking couplets.
When the festive couplets are pasted and a sumptuous Chinese New Year's Eve dinner is ready, the family will have a reunion for the Chinese New Year's Eve dinner, and then keep the New Year. This is the most ceremonial content during the Chinese New Year, and it is also the most New Year's custom during the Chinese New Year. At this time, in addition to being happy and happy, my heart is full of emotion, and I will fully feel the beauty of life and full of hope for the future.
Looking back on this year's Spring Festival, this experience is the most touching and unforgettable for me.

The most memorable thing about this year's Spring Festival is: New Year's greetings.
Usually, everyone runs around the world for life, working the road, some family affection, and some friendship are faint. If you usually have less contact, everyone will feel like the most familiar strangers to each other.
When it comes to the Chinese New Year, they fly back to their hometown from distant places like migratory birds. Seeing the familiar faces again, hearing the heart-warming folk sound, looking at a group of half-grown children who don't know who, I sighed in my heart that time had passed too fast, and I didn't even know the children in my own clan.
On the first day of the Lunar New Year, the festive atmosphere fills the streets and alleys. My children and I followed our uncles and brothers to the homes of our elders to pay New Year's greetings. In ancient times, New Year's greetings were a solemn ritual, but now they have been reduced to a form of sitting, talking, and blessing each other at the elders' homes.
The children are not teasing in the New Year's greetings for the sake of mixing the omen to make a New Year's money, and to get to know their own family members. It is rare for everyone to get together, and the children even take a mobile phone to play separately.
Sometimes, everyone is confused about the names of the children in each family, and the names of the teenage children are worn by Zhang Guan Li, which is also quite embarrassing.
Greeting the New Year, let those of us who are closest to each other get to know each other, so that our children can understand the history of the family and know the hardships of life.
Difficult, let's talk about their future plans.
Go home to pay New Year's greetings, warm and convenient. It's not like giving New Year's greetings to the leader, thinking twice, being afraid of this and worrying about that, thinking about the leader's taboos, and practicing what he says repeatedly. Painstaking and brainy, sweating after worshipping, this year's worship is really unforgettable.
Colleagues chatted with each other about the New Year, joked, and moved jokes together. I don't feel as good as going home for the New Year. Because: New Year's greetings at home, everyone is happy together, and their feelings are remarkable.
The warm sunshine sprinkled all over the courtyard, looking at the beautiful courtyard, talking about warm words, it is really heartwarming, the most memorable thing for me to remember the New Year is to pay New Year's greetings!

It's really bitter, it's not bitter. When we contacted Zhengbu, the instructor asked us to control our legs, and one control was ten minutes, of course, accompanied by the instructor, and in less than ten minutes, we were already staggering. >>>More
