What era is Huasheng?

Bi Sheng (year of birth and death unknown), Northern Song Dynasty cloth. A native of Huizhou (now She County, Anhui), (a native of Yingshan County, Hubei). At the beginning of the Song Dynasty, he carved for the bookstore.

During the reign of Song Qingli (1041-1048), he invented the printing technology of cement movable type based on practical experience. Before this technology could be promoted, Bi Sheng died. His handprint is collected by Shen Kuo's family, and his deeds can be found in "Mengxi Bi Tan" volume 18.

Movable type printing has the advantages of multi-purpose, reuse, printing more and faster, saving time and effort, saving materials, etc., which has a qualitative leap compared with engraving printing, and has a huge and far-reaching impact on the progress of printing technology and even world civilization in later generations. In 1989, Bi Sheng's tombstone was found in Yingshan County, Hubei.

The invention of movable type printing is a great revolution in the history of printing and one of the four great inventions in ancient China, which has opened up a broad road for the development of China's culture and economy and made a major contribution to promoting the development of world civilization. It is rumored that the descendants of Bi Sheng were found by the imperial court for forging coins with movable type cement, and the people of the nine clans who escaped by luck changed their surnames to Tian and Wan. Nowadays, although there is a place named Bijiapu in the local area, there are many surnames in Tian and Wan, and there is no surname in Bi.

It should be Bi Sheng, also called Bi Sheng, Bi Sheng (about 970-1051), Han nationality, a native of Qizhou (now Xishui County, Hubei) in the Northern Song Dynasty, an ancient Chinese inventor and the inventor of movable type printing.

Bi Shengchu was a printing shop worker, specializing in manual printing, in the printing practice, conscientiously summed up the experience of Yu Lun's predecessors, and invented clay movable type printing in the Northern Song Dynasty. It is considered to be the world's earliest movable type printing technology, recorded in Shen Kuo's "Mengxi Pen Talk". He died in 1051.

Movable type printing Tong Pai has the advantages of multi-purpose, reuse, printing and fast, saving time and effort, saving materials, etc., which has a qualitative leap compared with engraving printing, and has a huge and far-reaching impact on the progress of printing technology and even world civilization in later generations. In 1989, Bi Sheng's tombstone was found in Yingshan County, Hubei.

During the Song and Yuan dynasties, China's world-leading science and technology became a town: Huasheng of the Northern Song Dynasty invented movable type printing. Four hundred years earlier than Europe.

Breakthroughs were made in the compass and gunpowder, and they were widely used in the maritime industry and the military. In the Northern Song Dynasty, Shen Kuo had a book called "Mengxi Writings", which described many ancient scientific and technological achievements. Guo Shoujing compiled the "Calendar of Time", and the cycle of the year is the same as that of the current Gregorian calendar, 300 years earlier than the current Gregorian calendar.

The metaphor is the improvement and refinement of things, from the low level to the high level.

Self, also known as self-consciousness or self-concept, mainly refers to an individual's cognition of his or her own state of existence, which is the result of an individual's self-evaluation of his or her social role. In our experience, being aware of everything about ourselves and being different from other things around us and others is self-style, self-awareness. Everything we say here refers to our bodies, our physical and mental activities.

Sublimation has a variety of meanings. In physics, sublimation refers to the phase transition process of a substance from a solid state to a gaseous state without going through a liquid state due to a large temperature difference; In the interpretation of language, sublimation can be compared to the refinement and improvement of certain things, the sublimation of the ideological realm, and so on.

In addition, the word "sublimation" can also be used in fields such as psychology. People use the principle of sublimation to make science and technology more developed; The sublimation at the end of the article improves the ideological realm of the article.

Hello dear! I'm glad to answer for you, is Huasheng Co., Ltd. good? : It's pretty good according to the query.

The process in which a solid substance evaporates directly into vapor without going through a liquid process is called "sublimation". Sublimation is an endothermic process, generally at room temperature and pressure, sublimation will occur on any solid surface. For example, potassium iodide.

Dry ice, sulfur, phosphorus, camphor and other substances have significant sublimation phenomena. From the perspective of micro-dismantling, the process by which the molecules on the surface of the crystal break free from the attraction of other molecules and run to the outside of the crystal to become vapor molecules is sublimation. at the triple point.

When heated below the pressure, the solid-phase substance can be directly transformed into the gaseous phase without going through the liquid phase. For example, mothballs.

The clothes that are frozen outside in winter will dry out, and this is the result of sublimation.

We know that from macro, sublimation is the process of direct transformation of matter from solid to gaseous state. If the solid substance is placed in a closed container, when sublimated, the molecules with greater kinetic energy on the solid surface overcome the binding force between neighboring molecules and escape from the solid surface and directly become vapor molecules; On the other hand, when vapor molecules approach the solid surface due to irregular motion, they may be attracted to the solid surface molecules and return to the solid. At the beginning, more molecules escape from the solid surface than the number of molecules returned to the solid surface at the same time.

As the sublimation process progresses, the density of the vapors in the container increases, and so does the number of molecules returning to the solid. Until the average of the number of molecules that have escaped from the solid surface per unit time.

When equal to the average of the number of molecules returned to the surface of the solid per unit of time, the vapor in the closed container reaches dynamic equilibrium with the solid.

If the sublimation and condensation of a pure substance is carried out in the air on the ground. It is only necessary to specify the "pressure of the vapor of a pure substance" in the above condition as "the partial pressure of the vapor of the substance in the air". For example; Hygienic balls.

It is made of naphthalene (C10H8), and the temperature of its three-phase point is about open, and the corresponding pressure is megapascals; The temperature of the three-phase point of iodine is on, and the corresponding pressure is megapascals. Their sublimation and condensation are easy to observe at room temperature and in the air on the ground, so the junior high school textbook describes the sublimation phenomenon of the sanitary ball and the sublimation of solid iodine and the condensation experiment of iodine vapor.

On the one hand, it is necessary to overcome the binding force between the solid particles to do the work, and on the other hand, it is necessary to overcome the external pressure to do the work due to the volume expansion, so the substance needs to absorb a large amount of heat during the sublimation.

"Sublimation" has two meanings: the original meaning refers to the process of the object being directly dispersed from a solid state to a gaseous state.

Literary and emotional, the word refers to the elevation of the contained words or emotions to another new level and realm.

1. The object is directly converted from a solid state to a gaseous state;

2. By extension, the spirit and thinking of people have been greatly improved.

1. Sublimation, you can think of it as a name, such as sublimation shopping mall, sublimation electromechanical, sublimation groceries...

2. Sublimation has multiple meanings. In physics, sublimation refers to the process of phase transformation of matter from a solid state directly to a gaseous state; In the interpretation of language, sublimation can be compared to the refinement and improvement of certain things, the sublimation of the ideological realm, and so on. In addition, the word "sublimation" can also be used in fields such as psychology.

People use the principle of sublimation, and technology becomes more developed; The sublimation at the end of the article improves the ideological realm of the article.

Sublimation is the direct transformation of an object from a solid state to a gaseous state.

For example, eating popsicles in the summer, with cold air on them, is sublimation.

Sublimation refers to the direct change of an object from a solid state to a gaseous state.

The process by which a solid state directly becomes a gaseous state.

The object is directly changed from a solid state to a gaseous state.
