"Very good. Next, let's learn something. If country C's military power is so powerful that it overwhelms our country, what should you do for the legal rights that our country should enjoy on their land."
The child wanted to ask: Since it is someone else's territory, why are your rights still legal in someone else's territory? However, he was afraid of even more painful torture than before, so he could only say "yes".
Twenty-five years of the Republic of China——
In the training camp of the underground fortress——
Pushing open the glass door of the chemistry room, the boy who walked in looked childish, with a hint of pursuit of hope that was inconsistent with the environment here. The sleeves of his broad military uniform were a little too long, and his boots were beginning to fit.
He stood up so that he could walk without difficulty, but he still couldn't help but cover his nose when he smelled the combination of various pungent smells in the chemical room.
"The teaching today is chemistry, come here."
The doctor in the white coat is actually not a doctor. He is one of the researchers of the so-called "Operation Jade Broken" potion, and he just happened to be assigned to teach him something.
"In industrial applications, silver azide is the only one that can be mixed with other explosives. At last year's joint scholar's symposium, Broe scholars from the United States publicly reported for the first time the application of silver azide as a detonator charge.
It is used in underground mining, so silver azide is only used in special small detonators. Because silver azide has strong explosive power, it has better and superior applicability than lead azide in these aspects. At the same time,
It is suitable for use in detonating charges that require high thermal stability."
"Therefore, the detonating powder needs to have the performance of rapidly converting from combustion to detonation, but whether it can be actually used as a detonating powder also depends on its detonating ability. The so-called detonating ability means that the detonating explosive can ignite other violent objects after detonation.
The ability of an explosive to achieve stable detonation. The stronger the detonation ability of the explosive, the shorter the detonation growth period required for the agent to achieve stable detonation. The amount of explosive consumed during the detonation process is an important indicator to measure the detonation performance of an agent. Limit detonation
The amount of explosive refers to the minimum amount of detonating powder that can detonate a violent explosive. It is usually the minimum amount of detonating powder that can detonate 20 to 30 mg of crystalline RDX and achieve a stable detonation."
The doctor who was talking and operating, wearing gloves, picked up the lead trinitroresorcinol and RDX in the test tube and put them into a water bath oven for later use. He also used an analytical balance to weigh out 0.030 g of the processed RDX.
Accurate to 0.0002 g, place it in a copper tube shell, and press the medicine at a pressure of 117.6 MPa.
The doctor is different from the instructor who teaches the "quintessence of Chinese culture". He has no expression on his face, and he will not instill any small talk or righteousness into you. He will only state the facts in a serious manner.
What he learned yesterday was that the chemical element is barium, the day before yesterday it was boron, the day before yesterday it was phosphorus, the day before yesterday it was chlorine...
Let’s focus on these elements. Without exception, there is only one reason why they can become deadly weapons in certain special operations.
Barium is a white metal, one of the few in the table of chemical elements that can pass
Stable. Both its elements and compounds have a certain sweetness, but they are highly toxic, and even a small amount can kill people.
Therefore, barium is mainly used as a hardener for alloys, such as the representative bronze products. It is generally not used as a lethal weapon, but here, it is highlighted.
Boron is a semiconductor material with a black metallic luster. Compared with copper and silver, boron's electrical conductivity is weaker, about one-tenth of copper and silver. When the temperature of the metal rises, its electrical conductivity will weaken. And boron
But this is not the case. As its temperature rises, its electrical conductivity will increase. Its hardness is second only to diamond.
Borax is a very important boron-containing mineral and compound. Boric acid can be obtained after reacting with sulfuric acid. The aqueous solution of boric acid has a certain bactericidal effect, but it may cause poisoning, rash, and acute gastroenteritis.
Blood pressure dropped, muscle cramps, shock, etc., so I no longer continue to use it.
But in the eyes of doctors, it has an important symbolic use, which is to make sunscreen for nuclear reactors.
Organophosphorus compounds can be said to be neurotoxins. In the past, organophosphorus was used as a chemical weapon on the battlefield. Because of its strong toxicity, it caused the death of many people engaged in agricultural work in agricultural production. However, even these seemingly
Non-toxic phosphorus can still cause chronic poisoning in long-term exposure to high concentrations or during heavy use.
The poisonous gas used by the German army in 1915 - chlorine. Chlorine is a pungent yellow-green gas. The chlorine element belongs to halogen. The content in the air is very small, only about 0.0
About 03%-0.006%. If it adheres to the mucous membrane of the nasal cavity or throat and reaches a certain concentration, it will cause vomiting of blood due to poisoning, and may even be life-threatening. Therefore, chlorine gas was used during World War I
, was once used as a poisonous gas by the G country army.
On April 22, 1915, in the Ypres area of Belgium, when the Army of Country G and the Army of Country F were fighting fiercely, the Army of Country G suddenly released yellow-white smoke. In the downwind, this smoke drifted to the Army of Country F.
position. When the smoke entered the trench, the screams of the F soldiers were immediately heard, and they fell to the ground one after another... The scene was so tragic that it was inhumane.
At that time, the army of country G released 170 tons of oxygen. About 5,000 people in the army of country F were killed and about 14,000 people showed symptoms of poisoning. This was the first large-scale use of chlorine as a chemical weapon in human history and the second
An important link in the Second Ypres War that cannot be ignored.
In the Second War of Ypres, the army of Country E used chlorine as a chemical weapon in September of the same year and the army of Country F in February of the following year. After that, people used gas masks to fight chlorine. However, compared with chlorine
The chemical weapons phosgene and colorless, which are 10 times more toxic, can cause skin burns, emphysema, and liver function damage after contact with mustard gas.
The doctor weighed 0.03g of the treated lead trinitroresorcin, 0.020g of the tested detonator and RDX, accurately to the nearest 0.0002 g, and placed them successively in an aluminum-reinforced cap with a silk pad, using a pressure of 49.0 MPa.
Apply pressure and keep records.
"If you don't understand its principle, you won't be able to make weapons of mass destruction."
With some worry, the young man watched the separated liquid and gas go directly into the sewer. He said with some hesitation, "Excuse me, sir, these wastes are discharged directly without direct treatment. If they seep into the ground, what will happen to the surrounding areas?"
It is very likely that the soil will not be cultivated for hundreds of years, and even the plants that grow there are poisonous and endanger animals and people. Does it really matter?"
The doctor wore protective goggles, weighed 0.020g of rhodopsin on the balance, accurate to 0.0002g, and put the rhodopsin and the aluminum-reinforced cap that had been pressed with medicine into the copper tube shell in sequence, and filled it with 49.0 MPa
Press the sample into several rounds and number it, and record the quality of the tested explosive for each number for later use. When I heard this question, I suddenly stopped, turned around, and looked at the childish boy.
At this moment, time seems to have stagnated, and the blood in the human heart is no longer supplied. Only the interaction of those chemical reagents produces a "squeaking" sound.
"Have you ever thought about why, among so many people, 'General' only left you?"
The young man shook his head with a confused expression, and the doctor sneered softly, "Do you think that fighting is child's play, or that making a living for the rise of our country is child's play?"
"Mr. Mingjian, students have never thought this way."
"Never?"
The doctor's voice paused slightly, and then the cold words were slowly discharged together with the waste water and gas, "I know that your history class has been taught to you by another teacher, but that teacher once revealed that he was interested in your history class.
He was not satisfied with his concluding remarks, and now it seems that he was indeed right."
"I don't want to say what he has already told you. There is only one thing. You have to pay attention. War has always been about life and death. There is no peaceful coexistence. Death and injury are inevitable. Today we are fighting for the prosperity of our country.
The outcome was the result of their own resistance. If it really caused large-scale deaths, the murderers were also them. It is definitely not our turn to bear this responsibility. What I want to ask you is, when you care about the lives of their countries
, have you ever thought about the bodies of our country’s soldiers who shed their blood on the battlefield?”
The young man's eyes turned red but he didn't respond.
"The wastewater and exhaust gas issues you mentioned are of course clearly stipulated in international conventions. When any scientist is involved in an experiment, there is no one who has not sworn the word 'science', just like every doctor who enters the profession.
Before, everyone would raise their fists and declare their words to Nightingale, but times have changed. If the other side of the war had not been forcing us, how could we live like mice in this desert underground?
Our ‘Operation Jade Broken’ is going on here, but we can’t reunite with our loved ones? Who do you think is responsible for all this??”
Many waste materials produced by science must undergo extensive analysis before they can be discharged into general sewage ponds. The most obvious and extremely dangerous and harmful example is DDNP.
DDNP production wastewater mainly comes from reduction, diazotization, washing processes and floor washing, equipment and cleaning tools. DDNP wastewater has three major characteristics: large wastewater volume, deep dyeing, and complex composition. Therefore, its wastewater treatment is more difficult.
The mother liquor of DDNP contains many suspended small crystals, and crystals will precipitate after the mother liquor is cooled. Therefore, if
If it is not destroyed, the crystals will precipitate in sewers or drainage ditches, which is dangerous. The way to destroy the DDNP mother liquor is to use sodium sulfide to decompose it, destroy its diazo group, and make it lose its explosiveness. It is worth noting.
Unfortunately, the reaction between DDNP and sodium sulfide is very violent. During the decomposition reaction, hydrogen sulfide and nitrogen will be discharged, and heat will be released. Therefore, solid sodium sulfide cannot be added to the wastewater to avoid local overheating and an explosion accident.
Even after destruction, the mother liquor is still highly alkaline, and its components contain substances such as nitrobenzene and phenols. It cannot be discharged directly. This wastewater must be further treated to make it meet the discharge standards.
Can be discharged.
However, the discharge here cannot be discharged directly into ordinary wastewater pools at once. It requires further testing by relevant personnel before it can flow out.
Faubert once said in "Madame Bovary": "The poetic infection of nature is often given to us by writers."
In fact, when countless countries realized the convenience brought by chemistry, but also brought misfortune, they have consciously exerted their subjective initiative and utilized all resources to reduce the harmful consequences of chemistry a lot. This in itself is already a thing.
A gratifying thing——
Because if one day, the earth is no longer densely covered with fingerprints of farmers, and there are no more footprints of cuckoos who come to announce the spring and sing, then the regret at that time really needs the help of writers to give nature, then
The poetic and picturesque feeling no longer exists.
Therefore, for all the countries in the world that are immersed in the great joy brought by industrial civilization and unable to extricate themselves, those who dare to be the first to propose the control of chemical reagent emissions at the United Nations cannot be said to be heroes of the world, but at least they are
He is the first pathfinder in the wilderness and the earliest voyager in the stormy waves.
Zhou Zuoren once proposed in "On National Literature with Friends": "We must attack the paralysis of national cowardice; we must eliminate the poison of national obscenity; we must cut open the carbuncle of national obscenity; we must castrate the arrogance of the nation.
crazy".
The "arrogant madness" here means nothing more than ignorance and arrogance, as well as cloudy eyes that cannot see the truth of the matter.
Before the signing of the treaty in 1895, Mr. Rong Hong, who has made outstanding achievements in studying abroad on behalf of the current country, once sent more than 120 students to country A when the country was in crisis, and created a group of students for the subsequent countries -
-Such as Zhan Tianyou, the chief designer of the railway project who saved the national railway industry and stood on top of the world, Tang Shaoyi, the first foreign prime minister of the Republic of China, and the Director-General of Shipping, the founder of the police system... these are countless
Talent.
Even so, Rong Hong and the pioneer who dared to roar the first cry in the world, who had the conscience of a scientist, were slightly inferior to the pioneer who had the mind of an intellectual.
Since I have received the education of this civilization, my descendants should also enjoy the same benefits.
Instilling Western academic knowledge into China has made China increasingly civilized, prosperous and powerful.
The formation of the Mandarin Duck and Butterfly School has multiple reasons both inside and outside literature.
Judging from the historical situation of the late Qing Dynasty and the early Republic of China, the rapid overthrow of the late Qing Dynasty and the initial formation of the Republic of China society brought about the shaken and weakened order of ethical norms; the increasing enrichment of urban life also provided new emotional resources and resources for literati writing.
Space for speech, in which the development of the newspaper industry and the process of literary dissemination, the gradual emergence of market factors, has directly cultivated the secularization of novels. Representative writers of the Duck and Butterfly School such as Bao Tianxiao, Zhou Shoujuan, Xu Zhenya...
They all hold the dual positions of newspaper editors and popular writers - they can be said to be the forerunners of the times when they hear about social changes and evolution, witness the changes of the real order and daily life, taste the joys and sorrows of the new civilian society, and practice the new practices.
A new creed of urban civilization.
But no matter how many reasons there are, in the final analysis, there is only one overbearing and gentle word in mathematics that can describe it: yes and only.
There is and only this reason, there is only this person, and there is only such a thing, which is the first thing you shout out.
In his later years, Galileo was criticized by his students because he did not dare to adhere to the heliocentric theory: "A country without heroes is unfortunate."
"No, a country in need of heroes is unfortunate." Galileo replied.
There are so many cities in this world, and there are so many pubs in this city, but you just came to my place.
The young man's head was pressed very low, but he stubbornly refused to shed a tear. The doctor looked at him expressionlessly, turned around and continued the experiment just now.
"The calculation methods of C-J detonation wave velocity can be divided into two categories: the first is the trial and error method, and the second is the Newton-Raifson iteration method. Due to the following two reasons, the trial and error method is generally not as good as the Newton iteration
The method is good: ① If the amount of calculation is the same, the accuracy obtained by the trial and error method is lower; ② When calculating by the trial and error method, it is necessary to assume an approximate value of the solution every time, so the accuracy obtained is related to the experience of the calculation personnel. I
Now I’ll teach you how to use the Newton-Revson iteration method to calculate the speed of the C-J detonation wave.”
