　　2, the common payment method of imported sofa cover

　　Payment by letter of credit

　　(1) Definition and process

　　A letter of credit is a written document issued by a bank to an exporter as a conditional promise of payment at the request of the importer. When importing sofa covers, our company, as an importer, first applies to the issuing bank to open a letter of credit, and after the bank is approved, it will send the letter of credit to the notifying bank in the country where the exporter is located. After receiving the L/C, the exporter shall deliver the goods in accordance with the L/C and submit the relevant documents to the advising bank. Inform the bank to check the documents and send them to the issuing bank. After the issuing bank checks the documents to be in accordance with the L/C requirements, it will pay to our company and we will collect the goods against the documents.

　　(2) Advantages

　　 High security: Due to the involvement of the bank, the letter of credit payment method provides a higher security for importers like us. As long as the documents submitted by the exporter meet the requirements of the L/C, the bank must pay, thereby reducing our risk. For our company, this means that the payment will be made on the premise of ensuring that the quality and quantity of sofa covers meet the requirements, which guarantees our interests.

　　 Guarantee the quality of the goods: In order to receive the payment for goods smoothly, the exporter usually provides the goods and related documents that meet the quality standards in accordance with the requirements of the letter of credit, which ensures the quality of the goods to a certain extent. As a sofa cushion manufacturer, we have high quality requirements for sofa covers, and L/C payment can prompt suppliers to provide high-quality products.

　　(3) Disadvantages

　　 Complicated procedures: Opening a letter of credit needs to go through a number of links, including application, review, notification, presentation, etc., the procedures are more complicated, and the cost is relatively high. This may increase transaction costs and time costs for our company.

　　Poor flexibility: Once the terms of the letter of credit are determined, it is difficult to modify and lack flexibility. If special circumstances arise in the course of the transaction, the terms of the letter of credit need to be changed, which may cause the transaction to be delayed. In our production process, it may be necessary to adjust the specification and quantity of sofa covers due to changes in market demand or the adjustment of production plan, and the letter of credit payment method may bring some inconvenience at this time.

　　Payment by collection

　　(1) Definition and process

　　Collection refers to a settlement method in which exporters entrust banks to collect payment from importers. When importing sofa covers, the exporter, after shipping the goods, draws a bill of exchange together with the shipping documents to the collecting bank, and entrusts it to collect the money from our company. The collecting bank sends the documents to the collecting bank in the country where our company is located, and the collecting bank presents the documents to us. After checking the documents, our company can choose to redeem or D/A. If you choose the payment order, we can obtain the documents to collect the goods after payment; If D/A is chosen, we can obtain the documents after acceptance of the draft and pay for the goods when the draft maturates.

　　(2) Advantages

　　 The procedure is relatively simple: compared with the payment by letter of credit, the procedure of payment by collection is relatively simple, and the cost is relatively low. For our company, it can reduce transaction costs and improve transaction efficiency.

　　 It is more favorable to the importer: in the case of documents against acceptance, our company can obtain documents to extract the goods without paying for the goods, which is conducive to capital turnover. As a sofa cushion manufacturer, we can first put the sofa cover into production, and then pay for the goods after the product is sold, which relieves the financial pressure.

　　(3) Disadvantages

　　 Greater risk: under the collection payment method, the bank only acts in accordance with the exporter¨s mandate and does not assume the payment responsibility. If our company refuses to pay or accept, the exporter may face the risk that the payment will not be recovered. Similarly, if the quality of the goods supplied by the exporter is not up to the requirements, we may also face losses.

　　 Lack of constraints: For our company, due to the lack of strict constraints of the bank, there may be delays in payment or non-payment. This may affect our relationships with suppliers and is not conducive to long-term development.

　　Payment by remittance

　　(1) Definition and process

　　Remittance means a settlement method by which our company remits the payment of goods to the exporter through the bank. When importing sofa covers, we can choose to pay the exporter by T/T, M/T or D/D according to the contract. Telegraphic transfer is the most commonly used method of remittance. Our company issues telegraphic transfer instructions through the bank to remit the payment to the bank account designated by the exporter. After receiving the payment, the exporter will ship the goods to our company.

　　(2) Advantages

　　 Simple procedures: The procedure of remittance payment is the most simple and the cost is the lowest. For enterprises like us, it can save transaction costs and improve transaction efficiency.

　　Speed: Telegraphic transfer can usually complete the transfer of funds in a short period of time, which is conducive to the rapid progress of transactions. In our production process, if we need to import sofa covers urgently, the remittance payment method can meet our needs.

　　(3) Disadvantages

　　 Big risk: the remittance payment completely depends on the credit of our company, once we breach the contract, the exporter will face the risk of being unable to recover the payment. This is a big risk for exporters and may cause them to be reluctant to work with us.

　　(2) Lack of protection: Compared with letter of credit and collection payment methods, remittance payment methods lack bank protection, which is disadvantageous to exporters. Similarly, for our company, it is difficult for us to defend our rights and interests if the exporter does not deliver the goods on time or the quality is not up to requirements.

Beijing, July 17: An international study recently found that in January, when the Antarctic summer temperature is the highest, 57% of the melt water on the Antarctic ice shelf exists in the form of snow and mud. However, under normal circumstances, regional climate change models do not include This part of the melt water is calculated. This means that the amount of melt water on the Antarctic ice shelf is much higher than previously predicted.

Researchers from the University of Cambridge and other institutions in the United Kingdom published an article in the latest issue of Nature Geoscience that they trained machine learning models to analyze the monthly surface melt water records of 57 Antarctic continental ice shelves between 2013 and 2021. As well as mapping the snow and mud of the Antarctic ice shelf, it was found that in January, when the temperature in the Antarctic summer was the highest, 57% of the melt water on the Antarctic ice shelf existed in the form of snow mud, which is, snow soaked in water. The rest of the meltwater exists in surface ponds and lakes.

Researchers said that people usually use satellite images to map meltwater, but from the images, only meltwater lakes, etc. can be identified with the naked eye, and snow and mud are difficult to identify because it looks like the shadows of clouds. Machine learning models can use more satellite information such as light wavelengths to determine which areas are named snow and mud, making it possible to more accurately measure the amount of water melted on the ice shelf.

The study found that in the five major ice shelf areas, the amount of water melted on the Antarctic ice shelf caused by surface melt water was 28 times higher than predicted by standard climate models.

The surface melting of the Antarctic ice shelf mainly occurs in the summer of the southern hemisphere. Whether it is slush or melt water existing in surface ponds or lakes, it will affect the stability of the ice shelf and lead to sea level rise.

　　Due to the natural physical characteristics of liquid crystal display, the picture quality will change when users look at it from different angles. Compared with when looking at it obliquely, when the picture quality has changed to an unacceptable critical angle, it is called the viewing angle of the display. There are three definitions of viewing angle.Since then, more and more people have found that led display The value of, thus affecting the choice of many people. https://www.betopview.com/

　　Step 1 compare

　　Looking at the LCD from an oblique direction, compared with the front view, the white part will be darker and the black part will be brighter, so the contrast will decrease. Generally, the angle when the contrast drops to 10 is defined as the viewing angle of the LCD. That is to say, it is difficult to distinguish black and white when the definition is larger than this viewing angle. This article is most commonly used in the specifications of panel manufacturers and monitor manufacturers.

　　2. Gray scale inversion

　　Theoretically, from zero gray scale (black) to 255 gray scale (white), the higher the gray scale, the brighter it will be. However, at a certain large angle, the LCD may see that the low gray scale is brighter than the high gray scale, that is, it may see a phenomenon similar to black-and-white inversion, which is called gray scale inversion. The maximum angle that will not produce gray scale inversion is defined as the viewing angle, that is, beyond this angle, it is possible to see gray scale inversion, which is an unacceptable image quality.

　　3. Color difference

　　When you look at the LCD from different angles, you will find that the color will change with the angle, for example, the original white picture becomes yellow or blue, or the color becomes lighter, etc. As the angle becomes larger, when the color change has reached an unacceptable critical point, the angle is defined as the viewing angle.

　　Response time

　　The definition of response time is the time it takes to change from black to white plus the time it takes to change from white to black at the same point on the panel. The problem of LCD response time is because LCD controls the gray level of light by the rotation angle of liquid crystal molecules, and it takes time when the liquid crystal molecules rotate. Generally, the purpose of monitor is word processing and web browsing. Under normal circumstances, monitor will display the same picture for a long time. For a while, and then switch to a different screen. In this case, it doesn’t really matter how fast or slow the response time is for the user. However, if you want to use monitor to watch an animation or movie because the screen will keep changing, the response time will affect the quality of the screen.

　　Reaction time

　　Generally, the screen update frequency of LCD panel is 60Hz, that is, the screen will be changed 60 times per second, regardless of whether the currently displayed picture is changing, it will be re-displayed at this frequency, so the duration of each screen is 1/60 = 16.67ms. If the response time is much longer than this value, blurred images may be seen when the screen is moving.

　　ghost

　　The afterimage refers to the phenomenon that the previous picture does not disappear immediately after the picture switching, but slowly disappears. The afterimage is not the same thing as the reaction time. It may take two or three seconds to completely disappear, and the reaction time of the liquid crystal is ten to tens of milliseconds. A well-designed liquid crystal display, even if the reaction time is 15+35ms, can’t let the user see the afterimage. The mechanism of the afterimage is somewhat complicated, usually when the same picture is displayed for too long. Charged ions in the liquid crystal are adsorbed on both ends of the upper and lower glass to form a built-in electric field. These ions are not released immediately after the screen switching, which makes the liquid crystal molecules not turn to the required angle immediately. Another possibility is that the liquid crystal molecules are disordered during the state switching due to poor design of the pixel electrode. In this case, it is also possible to see the afterimage, so it is wrong to think that the afterimage will not be seen if the reaction time is fast.
