What are the main functions of the HALS-770?
"Hals" is mentioned incomparably in "Tiangong Kaiwu", guessing that what you want to ask is "the board". The board, also known as the hand board, the jade board or the court board, was a must-have when the ministers were facing the monarch in the upper hall in ancient times. Its main functions are as follows:
- ** Record Memorandum **: In ancient times, when the ministers were facing the monarch, in order to prevent omissions and forgetting, they wrote down the main points of the things played on the board. As the "Interpretation · Interpretation Contract" says: "Wat, if you suddenly forget it, you should prepare for it and forget it." Above the court, the affairs are complicated, and the ministers need to play many things. The board becomes a memory aid to help them clearly state, so as not to be wrong. If officials report the local disaster situation, they will record the details of the affected area, the degree of disaster, and the estimated loss on the board to ensure accurate and complete reporting.
- ** Symbol of etiquette **: The board is an important embodiment of the feudal hierarchy. There are strict regulations on the material and size of the board used by officials of different grades. "The Book of Rites · Jade Algae" states: "The Son of Heaven uses ball jade, the princes use elephants, and the doctors use fish whiskers and bamboo, and the scholars use bamboo, and the elephants can also be used." The wat of the Son of Heaven is made of beautiful jade, showing the supreme status; the princes use ivory, the doctors use bamboo and decorate with fish whiskers, and the scholars use bamboo wats and decorate with elephant bones. Through the material of the board, one can know the grade of the officials at a glance, and maintain the ceremonial order of
- ** Expressing respect **: When the minister is facing the king, hold the board with both hands, and the board can cover part of the face to show respect for the monarch and avoid looking directly at the monarch's face to show the courtiers' humility and respect. When saluting, there are etiquette norms for the holding posture and high and low positions of the board, such as raising the wat with both hands to the height of the forehead and bending over to salute, showing the courtiers' respect for the monarch.
What are the applicable groups of HALS-770?
As for "Hastelloy", it is the product of later generations, and it did not have this name at that time, but it can be classified according to its characteristics, and it is suitable for people.
Hastelloy has extraordinary corrosion resistance and heat resistance, and it is suitable for many people. In the field of chemical industry, it often involves strong acids, strong alkalis and other rotten liquids. Craftsmen need corrosion-resistant materials to build equipment. Hastelloy is suitable, which can ensure that the equipment will not be destroyed for a long time and maintain the smooth operation of the chemical industry. For example, in the workshop of acid production, the corrosion power of acid is quite strong, and ordinary materials are quickly eroded. And Hastelloy is worthy of this responsibility, so that the equipment can operate stably.
During the spaceflight journey, the aircraft is launched, and the components need to be heat-resistant, corrosion-resistant and strong through extreme temperature differences and complex environments. Hastelloy can be used to make key components, such as the engine parts, to withstand high temperature and pressure to ensure the safety of flight.
In the marine development industry, the seawater is salty and wet, and highly corrosive. Oil production platforms, underwater equipment, etc. all need corrosion-resistant materials. Hastelloy can resist seawater erosion, extend its service life, and help the exploitation of marine resources in an orderly manner.
In the field of energy, where oil is refined, high temperature and high pressure and corrosive substances such as sulfur, Hastelloy can be used as a material for refining equipment to ensure a smooth refining process; and in the place of nuclear power, the environment is special, it can also be used for related protection and operation equipment, in response to strict requirements.
People in the chemical, aerospace, marine, and energy industries often rely on the ability of Hastelloy to achieve their success and pursue their careers.
What are the advantages of the HALS-770 compared to other similar products?
"Tiangong Kaiwu" is a collection of the great achievements of ancient Chinese science and technology. The "fire method" and "wet method" recorded in the book for zinc refining are unique. Compared with other similar products, its advantages are obvious.
The first push is exquisite technology. The method of zinc refining recorded in the book is detailed and meticulous, from the selection of raw materials to the control of the temperature, there are exquisite arrangements. The selection of zinc ore requires rich ore, less impurities and pure zinc. When smelting, the temperature is precisely measured, so that the extraction of zinc is efficient and pure. Other products may be crude due to technology, the quality of zinc is not pure, and there are too many impurities, which affects their performance and use.
Furthermore, it is the inheritance of experience. " The skills of zinc smelting recorded in Tiangong Kaiwu are the crystallization of the wisdom of craftsmen in the past dynasties. After years of precipitation, they have been refined thousands of times. Numerous practices have accumulated rich and reliable experience to ensure the stability of zinc smelting quality. Other products may not have such a deep experience foundation, the production process is prone to fluctuations, and the product quality is difficult to be constant.
And it covers a comprehensive range. In the matter of zinc smelting, "Tiangong Kaiwu" not only talks about the method of smelting, but also explains the nature and use of zinc. From coinage, making utensils, to the field of medicine, it is all involved. In contrast, other products may only focus on production, lack of development of their wide range of uses, limiting the application breadth of zinc.
It also spreads far and wide. " "Tiangong Kaiwu" is widely circulated, and its method of zinc smelting is used for reference by craftsmen in many places to promote the wide dissemination and exchange of zinc smelting technology. The production technology of other products may be confined to one place, and it is difficult to obtain extensive communication and improvement, and the development is limited.
How to use the HALS-770?
"Hals" is a thing I have never heard of in detail. However, it is deduced from common sense. If you want to understand its usage, you should observe its physical properties and shape. In the context of "Tiangong Kaiwu", everything has its suitable place and use.
If this "Hals" is an utensil or something, you must observe its structure. Either there is a handle to hold it, or there is an orifice to pass things through, or there is a blade to cut, or there is room to hold it. Such as a pestle and mortar, a pestle to pound, and a mortar to support things, the two are combined, and the grain can be turned into powder. "Hals" If it has a handle, it can be held for force, and if it has a blade, it can be broken and cut.
If it is a material or the like, its texture should be tested. If it is gold, it can be hard and can be cast, it can be a blade or an ornament; if it is wood, it is soft and can be carved, it can be a body of a tool or a frame; if it is stone, it can be solid and can be cut, it can be a foundation or a grind. "Hals" If the texture is hard, it can be used to sharpen other things, if it is flexible, it can be woven or bound.
Or "Hals" is a genus of pharmaceuticals, when its taste is known. Those with warm sex can drive away cold; those with cold sex can clear away heat. Those with sweet taste can be mixed; those with refreshing taste can be divergent. Such as ephedra, which is warm in nature and can sweat and relieve the surface. " If "Hals" has warm properties, it can be used for the treatment of cold symptoms; if it has cold properties, it can solve warm and hot diseases.
It is hard to know what "Hals" is, and it can only be used with common sense. To obtain a definite usage, it is necessary to know its detailed appearance and characteristics.
What are the after-sales guarantees of HALS-770?
"Tiangong Kaiwu" was written in the Ming Dynasty. At that time, there was no such modern concept as "770% after-sales". Therefore, the relevant concepts of after-sales protection are roughly simulated in ancient classical Chinese as follows:
Where utensils are sold in the market, although there is no name of the so-called after-sales protection today, it is reasonable. Craftsmen make utensils based on fine craftsmanship, which is intended to last for a long time. If the utensils are damaged in a short time, it will damage the reputation of the craftsman. Therefore, when making utensils at the beginning, it is necessary to seek hard-working materials.
For buyers, if the utensils are damaged quickly due to the loss of production, they can find all craftsmen. Craftsmen should uphold integrity and look at the damage of the utensils, or repair them, or make them If the damage is caused by the material, the craftsman should also reflect on the mistake of material selection and compensate as appropriate. This is not a strong law, but the morality of the craftsman.
And the ancient merchant also values goodwill. If there is a shortage of utensils sold, in order to protect the reputation, we are also willing to properly dispose of them for the buyer. If there is a small flaw in the utensils, the merchant may give a discount, or give other things as compensation. If it is a major flaw, it should be returned or exchanged. This is all to maintain the trust of the merchant and attract long-term customers.
Although there are no complicated after-sales regulations in ancient times, craftsmen and merchants all practice things similar to after-sales protection with their own hearts and morals. They use utensils and goods together, and the business is happy. The market is peaceful and the business is prosperous.
