In the chess game, listening to cards is a skill, and listening to cards is a craft. Listening to cards means that you are about to enter the stage of Hu cards, which means that the final victory will not be too far away. Generally, players on the field basically start to listen to cards at the later stage of the game. At this time, whoever listens well and can master the skills of listening to cards will win the game earlier. Today, the new recruitment game will come to say for everyone?know Jilibet The market will definitely bring great influence to the whole industry. https://www.bl77777.com/

　　1. Listen to multiple cards-in a card type, players usually choose to listen to several cards. For example, 2,345,000, and the cards drawn at this time are 20,000 and 50,000. If it’s 2,345,600, then the draw cards are 10,000, 40,000 and 70,000. However, players need to pay attention to the fact that if some of the cards in Hu are likely to destroy the overall card type, such as one-stop, flat Hu and so on.

　　2. Listening is monotonous-it means that when players listen to cards, they just listen to a single card and want to make a pair.

　　3. Listen to the hole-for a simple example, if the cards in the player’s hand are 20,000 or 40,000, then the card type that the player listens to at this time is 30,000 holes.

　　4. Listen to the side card-listening to the side card is similar to listening to the hole. For example, at this time, the cards in the player’s hand are 70,000 and 80,000, so the card type that the player listens to at this time is 90,000.

　　5. Listen right-if there are two pairs in the player’s hand, at this time, you only need to make another set of engravings, and the other set will be used as a card. In this case, the player needs to listen to two cards, and this card drawing type is called listening right.

　　When listening to cards, players must pay attention to the card type of their family, and try not to listen to the same card type as their family, so as not to be called Hu by their family in advance. If your last family happens to be the dealer of the game in this bureau, it’s like avoiding listening to the same cards as your last family. If you can hide, you can hide!

　　[Keywords:” target=_blank> Optical fiber communication technology; Application development trend

　　The application of optical fiber communication technology mainly includes: using light wave as information carrier to realize communication function; Use optical fiber as a continuous propagation medium. At present, in terms of information communication, optical fiber communication belongs to the fourth generation communication mode. Its main characteristics are: light weight, fast propagation speed, small loss and small size, and its transmission frequency band is very wide, which can effectively resist most electromagnetic interference. These advantages make optical fiber communication gradually become the mainstream of society. At present, optical fiber is installed in most communication fields in China, and related businesses are still expanding, which has been recognized by more and more production and service fields. Understanding and studying the specific application of this communication technology can promote the development of informatization in China.

　　1 optical fiber communication technology

　　The so-called optical fiber communication is the optical fiber communication, which effectively transmits signals through optical fiber to achieve the purpose of information transmission. We can regard this optical fiber communication as an optical communication method with optical fiber as the medium [1″ target=_blank>. Among them, the main components of optical fiber are: coating, fiber core and cladding, while the inner core is usually only a few tens of microns or even a few microns, and its diameter is smaller than that of hair; Cladding is the middle layer, and the optical signal can be totally reflected in the fiber core by using the difference of specific refractive index between the fiber core and cladding, that is, the optical signal can be transmitted; Among them, the coating is mainly to improve the toughness of optical fiber, so as to protect optical fiber from damage. There is not only one light in the optical fiber communication system, but a large number of optical fibers are gathered together to form an optical cable. The reason why this kind of optical cable composed of a large number of optical fibers can transmit huge information in a unit time is mainly because the optical frequency of this optical cable is very high and the optical fiber transmission frequency band is very wide, so its transmission capacity is relatively large. The advantages of this optical fiber communication technology include: relatively small volume, very light weight, very few metal materials, strong electromagnetic interference resistance and radiation resistance, very good confidentiality, anti-eavesdropping, wide frequency band, good anti-interference performance, low price, etc. At the same time, the source of light materials used is very rich, which can reduce the application of many non-ferrous metals, and the diameter is very small and not heavy.

　　2 concrete application of optical fiber communication technology

　　2.1 Application in Communication

　　At present, in the field of communication, optical fiber communication technology plays a very important role by using optical fiber as the transmission medium. Especially in metropolitan communication, local communication and international communication industries, optical fiber communication technology has been widely used [2″ target=_blank>. At the same time, the optical fiber communication technology is constantly expanding and has become a very key technology in the communication field, which has effectively promoted the further development of the entire communication industry.

　　The quality management system of circuit board factory is one of the key points of audit. First of all, we should pay attention to the quality control process, including raw material procurement, production process control and finished product inspection. These processes should be clear, standardized, and can effectively control product quality. Secondly, we should pay attention to quality certification, such as ISO9001 certification. These certifications can prove that PCB factory has certain quality management ability, which is an important basis for customers to choose partners.

　　Second, the production capacity and equipment status

　　The production capacity and equipment status of PCB factory are directly related to the quality and delivery capacity of products. In the audit process, we should carefully understand the production capacity of PCB factory, including the number and scale of production lines, production cycle and production capacity. At the same time, we should pay attention to the condition of the equipment, ensure that the equipment can run normally and have a certain maintenance and update plan.

　　Iii. Environmental management and safety measures

　　Environmental management and safety measures are issues that modern enterprises must pay attention to. When auditing the PCB factory, we should pay attention to its environmental management measures, including the treatment methods of wastewater, waste gas and solid waste, and whether it complies with relevant environmental laws and regulations. At the same time, we should pay attention to safety measures to ensure that the safety risks in the production process are effectively controlled and the personal safety of employees is guaranteed.

　　Fourth, supply chain management

　　Supply chain management is another important aspect of PCB factory audit. First of all, we should pay attention to the procurement of raw materials to ensure the quality and reliability of raw materials. Secondly, we should pay attention to supplier evaluation to ensure that suppliers have certain quality management capabilities and can deliver goods on time. The quality of supply chain management is directly related to the quality and delivery ability of products, and it is the key to the long-term stable operation of PCB factory.

　　When auditing PCB factories, we need to pay attention to quality management system, production capacity and equipment status, environmental management and safety measures, and supply chain management. Only by fully understanding and grasping these problems can we ensure the selection of suitable PCB factory partners, thus ensuring product quality and delivery capacity. At the same time, PCB factory should actively improve and perfect its own management system to meet the needs and requirements of customers.
