The composition of about 500 words is related to the prohibition of setting off fireworks and firecrackers.

Government departments formulate laws and regulations, of course, there is no need to discuss with ordinary people one by one. But sometimes, in order to reflect the necessary justice and democracy in decision-making, people often explain why this law or regulation is made.

For example, when the city's ban on setting off fireworks and firecrackers was first promulgated, it was publicized and explained to the people in newspapers, radio and television stations.

It is said that setting off fireworks and firecrackers in cities is very harmful. One explanation I saw was an example of a survey in a city in a certain year.

First, it is easy to catch fire. Because of the fireworks, how many fires have occurred, how many houses have been burned, how many fire officers and soldiers have been dispatched, how many thousands of dollars of property have been lost, and so on.

Second, it is easy to hurt people. How many children's hands were injured, and how many children's eyes were blinded or injured by fireworks; More because of the fire, how many people were burned to death, how many people were burned to death and so on.

The third is to pollute the environment. The discharge of fireworks and firecrackers makes the air dirty, which is easy to cause many diseases; Noise disturbs the environment and affects people's rest, and so on.

Therefore, "according to the strong demands of the broad masses of the people"; "With the consent of the NPC Standing Committee"; Resolutely prohibit fireworks and firecrackers in cities.

Which specific groups of people strongly demand it? No one questioned it. Because if you ask questions, you may be regarded as an idiot.

Later, it was lifted, of course, it was limited. That is, fireworks and firecrackers are only allowed during the Spring Festival, and they are still prohibited at other times. The lifting of the ban during the Spring Festival is actually the lifting of the ban throughout the year, because except for a few cases such as weddings, funerals and weddings on weekdays, who will be mentally abnormal and work hard to set off fireworks and firecrackers?

So, why lift the ban? As a rule, there is always an explanation.

Sure enough, the media explained that the Spring Festival is a traditional festival in China, and setting off fireworks is a traditional way to celebrate. In order to carry forward national traditions, invigorate social air and improve people's quality of life, it is "according to the strong demands of the broad masses of the people"; "With the consent of the NPC Standing Committee"; Fireworks and firecrackers resumed during the Spring Festival.

Which specific groups of people strongly demand it? I haven't heard anyone question it. Because one is that there is no place to interrogate, and the other is that if someone does interrogate, they will be regarded as idiots.

What about the fire, burning people and houses? How to avoid blowing up children's hands and eyes? How to explain air pollution and noise pollution to the people?

None of this is said. It may be that fireworks and firecrackers are now high in technology and will not catch fire and hurt people; I still hope that the people themselves will pay more attention. Because this is "according to the strong demands of the broad masses"; With the consent of the NPC Standing Committee.

Some people say that it is actually the interests that are at work. Fireworks have a high added value, and you can get rich profits from this business. So these interest groups lobbied the government to lift the ban. And the government can also get some generous taxes for the people. Why not? As for the social damage caused by fireworks and firecrackers, as well as Mao Dun's position before and after the ban, in addition to finding some reasons to prevaricate the people, others have to be put aside for the time being.

This is the opinion of the "broad masses" before and after.

"The broad masses of people" is a very useful phrase. Although this sentence is virtual, it represents the majority, contains authority and is full of power; "The people are the masters of the country" and "doing justice for heaven" are reasonable. People who can be officials will never forget this sentence when they talk or write articles. Those who are interested in being an official should not only learn other theories well, but also learn this sentence by heart.

Does anyone know the amount of gunpowder used to set off firecrackers in China every year? Converted into TNT equivalent. Let's do the math!

The annual output value of fireworks in China is more than 654.38+0 billion yuan, less than 20 billion yuan, and domestic sales are 5 billion yuan. According to the calculation in the industry, the gross weight of high-grade fireworks (such as high-altitude fireworks) is about one kilogram in 50 yuan (the ex-factory price is so low, the industry has high profits, many patterns and deep water), and the gross weight of ordinary firecrackers can be converted into TNT equivalent of 0. 1 kg to 0.2 kg on average.

Therefore, it is estimated that the equivalent of TNT is in the order of 10 million kilograms to 1 million kilograms.

Ask for fireworks composed of special symbols ~ urgent!

Person in charge of report:

The truthful report is as follows-

There are several schemes to produce patterned fireworks;

The oldest is the gunpowder array fixed on the ground, which is ignited together or pre-programmed, and ignited at certain intervals so that children can understand it.

Or there is a three-dimensional cavity made of paper in the projectile, arranged according to the pattern you need. This is a customized process according to customer's requirements. There are bonded rolling powder balls in the cavity, which will explode after the fireworks are launched, and the burning and luminous powder balls can form simple patterns in space. The price 1000 yuan to 3000 yuan, and the production cost is less than that of 500 yuan.

Now they all learn from the practice of foreign countries ten years ago and adopt programmable electronic delay fuze. Because there are many imitation manufacturers, the original special chip has long been replaced by a general-purpose single chip microcomputer, and the fuse cost starts from 10 yuan. The firing tubes at fixed intervals on the ground, the direction of each firing tube should be tested, which is the dot matrix pattern of the fireworks in Beijing Olympic Games and Tiananmen Square on the 60th anniversary of New China. The standard price of this kind of barrel array and ground programming launch computer is more than one million yuan respectively. For ordinary customers, 20,000 yuan can open a rough system. The minimum cost of typing a word is 20 thousand, and the reserve price is also open. An integrated circuit controls timed fireworks from 100 yuan to 1000 yuan, and ten points is 1000 yuan, earning the franchise of producing fireworks, transporting fireworks, storing fireworks and launching fireworks. Big customers not only type a few words, but also provide supporting services.

Fireworks is an immoral and sinful industry;

It pollutes the environment, wastes strategic resources, intensifies bribery, endangers public order and threatens life safety.

The pollutants produced by fireworks and fireworks combustion are similar to those emitted by automobile exhaust and coal combustion. Forget firecrackers, it is harmful nitrogen and sulfur compounds; When the colorful luminescent substances of fireworks burn, they will produce more toxic substances. For example, firecrackers should emit particularly bright white light and silver light. In addition to adding aluminum and magnesium, rare earth element titanium should be added. To produce colored light, non-ferrous metals are essential, and heavy metals and rare earth metals have good flame color effects, such as manganese, chromium, nickel, vanadium, molybdenum, tungsten and cerium (the main flint materials of traditional lighters). Smokeless fireworks mainly use nitrocellulose, which has been around for more than 0/00 years. Hunan Province, Jiangxi Province and the Ministry of Science and Technology have invested more than 100 million yuan, and the low-pollution fireworks developed are not up to the level of R small enterprises. Compressed air cold strike (from 15,16th century) fireworks, time programmable preset software and integrated circuit delay electronic ignition fuze (from 1940) are engineering technologies that have been publicly used in this field abroad for more than ten years.

People are rich and powerful. What about you? ! ! ! !

There are too many social problems,

The output value of fireworks in China is more than 654.38+00 billion yuan, less than 20 billion yuan. To support a large number of production enterprises, what industry can be used to change birds?

Fireworks and firecrackers management departments, safety supervision departments, public security departments, fire departments, hospitals, medicines, surgical instruments, funeral homes, etc. It is indispensable for this industry to rely on these to eat.

If these people don't shoot, they will do more dangerous things, and they must let these class enemies vent, vent and release their anger. Therefore, existence is reasonable! ! ! ! ! ! ! !
