The principle of tempering steel was to make carbon react with oxygen to produce carbon dioxide, thereby reducing the carbon content. The chemical equation of the reaction was: C + O <2 $ CO₂。
The following are some of the simpler chemical explosive formulas: 1. Metal Caesium + Water: Alkali metal Caesium is the most active among the alkalimetals. When it comes into contact with water, it will not only spontaneously combust but also self-destruct. During the reaction process, it will quickly release hydrogen. 2. [Triiodinated nitrogen: In a dry state, it will explode when it is lightly touched, such as air currents or light. The explosion will be loud and will be accompanied by purple iodinated vapor.] 3. Metal Cesium + Fluoric gas: Cesium is the most active metal in the periodic table, while Fluoric gas is the most active non-metal. When the two are placed together, they will explode. 4. " Condensed sulfuric acid + alcohol: Add concentrated sulfuric acid into the alcohol slowly drop by drop, then seal the container. As the alcohol is oxided, the heat reaction will cause the alcohol to burn and explode. 5. Manganic acid: It has super strong oxidisation and can react with almost any organic matter quickly and burn and explode, such as paper, leaves, wax, gasoline, kerosene, and even fuses.
" Tempered through a thousand times before becoming steel " meant that a person or thing needed to go through a lot of tempering, trials, and polishing before it could become strong, excellent, or reach an ideal state. From a human's point of view, whether it was personal growth, career pursuit, or spiritual cultivation, they all needed to experience many difficulties and setbacks. It was just like how young officers had to go through all kinds of training at the grass-roots level, overcome their arrogance, do small chores, deal with trivial matters, accumulate experience in practice, and increase their talents in order to become outstanding officers. It was also like how soldiers had to go through multiple physical and mental tests, overcome difficulties such as injuries and illnesses, and stick to their dreams and work tirelessly to become outstanding soldiers and obtain honor. In the face of all kinds of hardships in life, one should not be afraid to retreat, but should accept them positively and optimistically, because these hardships are the only way to growth and success. Only by experiencing countless tempering can one be as tenacious as steel, realize one's own value, and move towards success. From the perspective of objects, for example, the refining of steel required countless hammering, smelting, and other processes to remove impurities and finally become tough steel. This statement emphasized the necessity and importance of the tempering process.
The chemical formula of TNT was C H N O or C6H2CH3 (NO2)3.
The phrase " steel can only be formed after repeated tempering " meant that a person or thing needed to go through countless tempering, trials, and polishing to become strong and excellent, just like how steel needed to go through repeated tempering before it could be formed. In the process of a person's growth and development, whether it was in learning, career pursuit, or moral cultivation, they would face all kinds of difficulties, setbacks, and challenges. Only by enduring these, constantly learning from their failures, and constantly working hard to improve themselves could they finally reach the ideal state, achieve success, or realize the sublimation of their own value. It emphasized the importance of training and persistence on the path of growth and success.
In 'The Martian', there are likely chemical formulas involved in the protagonist's attempts to grow food on Mars. He has to deal with the Martian soil and its composition, which can be represented by chemical formulas. Also, in some superhero stories, like the Hulk, there could be a fictional chemical formula for the gamma radiation that transformed Bruce Banner. This formula might involve elements and compounds that are not fully understood in our real - world science.
Chemical formulas in science fiction can add a sense of scientific authenticity. They can be used to create a sense of mystery too. Let's say there is a chemical formula for a time - travel serum. The author can play with the idea of how the elements in the formula interact to make time - travel possible. It can also be used to show the progress of science in the fictional future. A story could be about scientists discovering a new chemical formula that revolutionizes space travel by creating a fuel that is more efficient than anything we have today.
Tempered Steel referred to the process of tempering and smelting metal into tough steel. This idiom conveyed the key to success through hard work and constant trial and error.
The following are some formulas for calculating the theoretical weight of H-beam steel: 1. Weight per meter (kg)=(web height h× web thickness t1+ wing width b× wing thickness t2×2) ×0.00785. 2. The theoretical weight of the hot rolled H-shaped steel =(hh +2r (b-d)+ 0.8584 (r2-r12)) ×L×7.85×1/100 (where h is the height (mm), b is the foot width (mm), d is the waist thickness (mm), r is the inner corner radius (mm), r1 is the edge corner radius (mm), and L is the length (m)). 3. Weight (kg/m)= 0.00785 x cross-section (mm2) x length (m). The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
In the process of smelting steel, the steel produced by the tempering process would have a lower carbon content. The main difference between iron and steel was the carbon content. Iron had a higher carbon content, and after repeated tempering, a portion of the carbon was oxided and removed, thereby reducing the carbon content. This resulted in a new material, steel, with a certain carbon content.
The most impressive story in How Steel Was Tempered was the experience of the protagonist, Pavel Kochagin, during his internship at the Iron and Steel Industry Company. There, Kochagin not only encountered various difficulties and challenges, but also made many friends. He had experienced setbacks such as production accidents, work mistakes, and breakups, but he had always maintained a positive attitude and continued to work hard to learn and grow. Through this experience, Kochagin not only learned the spirit and working methods of steel workers, but also understood the meaning and value of life.
