1. Do you mean virtual currency like BTC and counterfeit currency like LTC? At present, the country has not explicitly stipulated that the Internet virtual currency is illegal, nor has it been recognized as legal. Now it belongs to the gray zone. However, many foreign countries have used virtual currency to trade goods, because virtual currency is used for Internet, and there is no need to convert us dollar or euro. If you feel satisfied, please give me some dog money
2. Is more than the general disk capacity of the disk, some game capacity will use D9, but D9 expensive
3. The DVD disc is composed of two substrates. Each substrate can hold two layers of data at most. The DVD head can read these two layers of data by adjusting the focal length
D5, that is, single-sided and single-layer, with a maximum of 4.7G. Data is printed on one side and words or patterns are printed on the other side
D9, that is, single-sided and double-layer, with a maximum of 8.5g, with data on one side and text or pattern printed on the other side.

4. With the development of DVD, because of the new technology, the interactivity of DVD becomes stronger and stronger, and the load information is more and more, so it is more and more complex and longer. In the process of development, DVD has mainly experienced the following three stages: sprouting stage, expanding stage and mature stage. Here are the specific conditions of these stages
the first stage is the initial stage of DVD market
ring this period, movie companies headed by Warner and Columbia mainly released single-sided single-layer (D5) DVD discs. Due to the limitation of capacity, there was little additional content in the disc except for the movie itself which lasted about 2 hours. Generally, there was a theater version of trailer and cast & crew, Moreover, the menu of DVD is very simple and static, and e to the lack of additional content, there are few options in the menu
with the development of technology, double-sided and single-layer (D10) discs have become popular. Generally, one side is the full screen version of the film, and the other side is the wide screen version of the film, such as tornado and Qianlong Hongtian released by Warner in the early stage. In fact, D10 has no essential difference from D5 in terms of additional content, but because it contains two different formats of positive films at the same time, you can get the best display effect whether you are a 4:3 TV or a 16:9 TV, which is favored by many fans
e to the immature proction technology of DVD in this period, most of the picture quality is not ideal from today's point of view, which can clearly show the sense of graininess<
in the second stage, the expansion period, a large number of Se versions emerged, and DVD began to share equally with VHS videotapes
with the expansion of consumer groups, all the major film companies in the United States have launched their own DVD discs one after another. At the same time, DVD has graally squeezed LD out of the mainstream market for its excellent image quality, sound effect and unique interactivity, And with VHS video, this time appeared to SE version as a representative of the new type of DVD. Se, short for special edition<
in the third stage, the mature stage, publishers began to take DVD as the main body of distribution.
in the early stage of adoption, e to the immature technology, there were some small problems, such as Warner's "matrix" D9 DVD could not be read smoothly on many machines, although Warner did not admit what caused the problem, But it's generally believed that it's out of the proction and lamination of D9. In addition, D9 is still unable to perfectly solve the problem of layer change pause. However, with the stability of D9 technology, more and more DVD still adopt this format. There are two main reasons: first, the positive film and more and more additional content make the capacity of D5 unable to meet the demand for a long time; The second is the emergence of a large number of positive films with a capacity of more than 4.7G. If D10 is used, players will manually change faces in the middle of appreciation, while D9 does not have this problem; Third, in order to avoid piracy, the distribution company intends to make the positive film capacity more than 4.7G and add a lot of additional content, which makes it difficult for piracy
at present, the DVD in zone 1 is basically in single-sided and double-layer D9 format, with a maximum capacity of 8.5g. Depending on the length of the film, the length of the positive film is generally about 4g-7g. Generally, there are all kinds of additional information about the film, such as shooting gags, clips deleted for some reasons ring the public show, comments of the director and actors on the film, etc., which have certain collection value. There are also legitimate "terminator sequel" released with D18 and double D9 format for players to choose from. In China, single-sided and single-layer D5 or single-sided and double-layer D10 are commonly used for DVD, and D9 has appeared recently. The maximum capacity of D5 is only 47g. Due to its capacity, there is little additional data except positive film. D10, however, mostly has one film on both sides, but the price is not very high. Therefore, it has a high cost performance ratio, but it also has no additional content. In addition, D10 includes positive films and a lot of additional content, but in this way, it needs to be manually changed in the middle of the broadcast. It is a helpless way. I believe that in the future, it will completely transition to D9 or even D18

5. DVD can be divided into the following categories in terms of capacity: DVD 5, DVD 9, DVD 10 and DVD 18, with capacities of 4.7G, 8.5g, 9.4g and 17g respectively. DVD 9 is one of the formats on DVD capacity< DVD adopts VBR format of MPEG2 to compress image. It is a kind of dynamic variable data stream compression, ranging from 1m to 9.8m. The largest data stream can reach 10.8m in total. It is very different from VCD in the past. VCD adopts CBR format, the data stream is fixed, and the length of each disc is fixed; The length of DVD's stored movie can be changed. The data stream is small and the time is relatively long. On the contrary, the length of DVD's stored movie is short when the data stream is large. This is also the main reason why the quality of DVD 9 is higher than that of DVD 5

The capacity of DVD9 is almost twice of that of DVD5. For films of the same length, large data stream compression can be used in DVD9 to ensure the quality of the picture. In order to accommodate the whole film, DVD5 can only rece the data stream and sacrifice the quality of the picture. Generally speaking, DVD 5 can store movies for about 100 minutes, and its picture quality can be guaranteed. Although the DVD standard is 133 minutes, it also depends on the quality of the original materials, and sometimes the quality of 133 minutes can not meet the DVD standard. The capacity of DVD 9 is just suitable for the actual situation in China. With large capacity, we can try our best to improve the collected data stream, make up for the lack of raw materials, and give you a real DVD experience
Second, advanced technology and protection of right. The technology content of DVD9 is quite high in both proction and proction. The proction technology of DVD 5 has been mature. At present, the vast majority of the pirated market is DVD 5. The proction complexity of DVD-9 is much higher than that of DVD-5, and there should be no errors in every step and option in the whole process. At present, there is still a major problem in the detection of DVD-9. Now DVD-R can record DVD-5, but there is no way to record DVD-9 for the time being, so the detection is relatively cumbersome and takes a little more time. At present, the technology of die cutting and disc pressing of DVD 9 is not perfect in China, and only a few manufacturers can proce it. There are many more manufacturers of DVD 5< Third, the program is rich in content. Generally speaking, the content of DVD 5 is relatively single, and it has not reached many functions of DVD standard. DVD 9 procts add some functions of real DVD, including multi language, multi subtitle, multi angle and other functions, so that consumers can truly realize the advantages of DVD< 4. High quality. The overall quality of DVD 9 is higher than that of DVD 5. The DVD9 uses pure gold as the reflector, which is golden in appearance, while the DVD5 is silver.

6. DVD is divided into many specifications according to its capacity. According to the different capacity, DVD can be divided into single-layer single-sided, single-layer double-sided, double-layer single-sided and double-layer double-sided. The DVD head can read these two layers of multi-faceted data by adjusting the focal length
the most common is D5 disc, which is short for DVD-5, that is, single-layer single-sided disc, with a maximum capacity of 4.7G. The disc has only one layer and only one side has data written on it. D5 disc can meet a 100 minute film with Duby digital surround sound system and two text subtitles
D9 disc, which is the abbreviation of DVD-9, is more common, that is, double-layer single-sided data disc, with a maximum capacity of 8.5g. The films released on D9 discs are usually films in AC3 and DTS sound systems, or long films with more than 120 minutes
in China, D10 disc, which is short for dvd-10 disc, is a single-layer double-sided disc with a maximum capacity of 9.7g. Both sides are data planes, and the film name is printed on the disc core. Most of the films released in the form of d10 are two films on one disc
the rare one in China is D18, which is the abbreviation of DVD-18, that is, double-sided double-layer disc, with a maximum capacity of 17g,
both sides are data planes. This kind of disc is usually a film with many movies. Or in addition to movies, there are movie music stored in DVD-audio format.
the most common is D5 disc, which is short for DVD-5, that is, single-layer single-sided disc, with a maximum capacity of 4.7G. The disc has only one layer and only one side has data written on it. D5 disc can meet a 100 minute film with Duby digital surround sound system and two text subtitles
D9 disc, which is the abbreviation of DVD-9, is more common, that is, double-layer single-sided data disc, with a maximum capacity of 8.5g. The films released on D9 discs are usually films in AC3 and DTS sound systems, or long films with more than 120 minutes
in China, D10 disc, which is short for dvd-10 disc, is a single-layer double-sided disc with a maximum capacity of 9.7g. Both sides are data planes, and the film name is printed on the disc core. Most of the films released in the form of d10 are two films on one disc
the rare one in China is D18, which is the abbreviation of DVD-18, that is, double-sided double-layer disc, with a maximum capacity of 17g,
both sides are data planes. This kind of disc is usually a film with many movies. Or in addition to movies, there are movie music stored in DVD-audio format.
7. Simply speaking, it's right to have different capacities.
if it's complicated,
DVD-5 (12 cm, single side / single layer) 4.37 GB (4.70 BB)
DVD-9 (12 cm, single side / double layer) 7.95 GB (8.54 BB)
if it's a DVD disc, often D5 is just a positive film. Generally speaking, 130 minutes of positive film can also be put into D5, and D9 may have more audio track choices and gags, The picture quality of D5 is not necessarily worse than that of D9

8. It is a kind of carbon structural steel bar with high yield strength and good toughness
carbon structural steel, English Name: carbon structural steel, a kind of carbon steel. The carbon content is about 0.05% ～ 0.70%, and it can be as high as 0.90% in some cases. It can be divided into ordinary carbon structural steel and high quality carbon structural steel. It is mainly used in railway, bridge, all kinds of construction engineering, manufacturing various metal components under static load, unimportant mechanical parts without heat treatment and general welding parts.

9. On October 22, 2009, Microsoft officially released Windows 7, and DirectX 11 integrated into windows 7. In fact, DirectX 11 is only a substantially enhanced version of DirectX 10, not a complete innovation of 9.0c and 10.0/10.1. DirectX 11 brings five important features: tessellation (subdivision surface technology), multi threading (multithreading), directcompute (general computing), shader model 5.0 (rendering engine 5.0) and texture compression (texture compression), which bring users better visual enjoyment. Win7 directly provides DirectX 11, while Vista can support 11.0 by upgrading the DirectX driver package
you can regard D11 as the upgraded version of d10, D10 as the upgraded version of D9, and D11 corresponds to win7 operating system, which needs certain configuration support. Under the same configuration, it can be said that D11 card should be better than D9 card< br /> http://ke..com/view/1630503.htm
