1. As for the recording disk, Tsinghua can use it, and pioneer is the best recorder (personal opinion), but there are few good pioneer agents in China. Sony is good, read disk and burn are excellent, as long as you do not object to using Japanese goods, is a good choice, do not use MSI. Don't use Samsung. I've tried all these, garbage in garbage (personal opinion). Support the domestic procts, please use Jianxing domestic best (or personal opinion), pirates favorite, thick leather and easy to operate (unit boys say) read disk is good, burning is also good. The price is also cheap. After sales, anyway, my side is OK. If you have any problems, you can replace them. I just recommend the brand and model. You can see for yourself. It's almost the same anyway
in addition, you can go to the recording bar to have a look. It's all about how to choose and buy. You can also learn from the bad goods you buy. I went there before I bought it
the above are personal opinions, please don't scold me. Hee hee^^

2. First of all, we should understand the meaning of water resources. Water resources can be divided into broad sense and narrow sense. Water resources in a broad sense refers to all water bodies on the earth; Narrow sense of water resources is what we usually call water resources, refers to the earth's fresh water resources
water on earth is stored in the ocean, land and atmosphere. Ocean water accounts for 97%, and is the main body of water on the earth. Atmospheric water mainly exists in gaseous state with the smallest specific gravity. Land water can be divided into fresh water and salty water according to salinity. Salty water is mainly distributed in Inner Flow lakes and underground salty water. Fresh water accounts for 2.5% of the global water reserves, including river water, fresh water lake water, underground fresh water and glaciers. Glaciers and deep groundwater account for 98% of the total fresh water, which is difficult to use under the existing technical conditions. At present, the freshwater resources used by human beings are mainly rivers, lakes and shallow groundwater, accounting for only 0.3% of the global freshwater resources
it can be seen that the water resources available for human use on the earth are limited. With the growth of population, the improvement of people's living standards and the development of social economy, the consumption of water resources has increased dramatically, resulting in the rection of available water resources. This is the limited water resources, but also by varying degrees of pollution, what is the cause of water pollution? It is mainly instrial wastewater, pesticide and fertilizer in agricultural proction and urban sewage. The lack of freshwater resources is not a unique problem for indivial countries, but a problem faced by global development. The world bank's 1995 survey report pointed out that 80 countries, accounting for 40% of the world's population, are facing a water crisis. About 1 billion people in developing countries cannot drink clean water, 1.7 billion people do not have good sanitation facilities, and about 25 million people die from drinking unclean water every year
China is rich in water resources, ranking sixth in the world; However, China's per capita share of water resources is small, only 1 / 4 of the world average; China is short of water resources. Saving and protecting water resources is the core way to solve the problem of water resources in China. Although the construction of water conservancy and inter basin water transfer can effectively alleviate the problem of water shortage in local areas and local time, it can only treat the symptoms, not the root cause
water resources are renewable resources. From the point of view of the earth's water environment and the total amount of water resources, they should be recyclable and sustainable. However, on the one hand, water resources do not mean all the water bodies in the world, but only the fresh water resources that can be used by human beings, and the proportion of these fresh water resources that can be directly used by human beings is very small; On the other hand, in a certain space and time, e to natural reasons (such as climate, river distribution), or human reasons (such as unreasonable use, pollution and waste), water resources are not only limited, but also may be exhausted. Therefore, we should dialectically and scientifically understand the process of water cycle and the attributes of renewable resources, and understand why the "water ball" in our life also causes "water shortage". We should protect water resources, save every drop of water, and not let our descendants see the last drop

bitcoin has not experienced big ups and falls for several days, and it may have much to do with the bubble of the market. Tesla's float is up to 990 million US dollars, or about 6 billion 400 million yuan. Some people really like this price, while others worry about it. After all, some people have made a lot of money in bitcoin, but some people think that the bubble will always be broken. The high price now does not know what will bring serious consequences. p> Third, the price of bitcoin can not be sustained< p> JPMorgan team believes that bitcoin's surge since January this year seems to be more affected by speculative capital flows. Analysts at the bank pointed out that in the past five months, the total institutional inflow was only about $11 billion, but the market value of bitcoin increased by about $700 billion. According to Xinhua news agency, JP Morgan believes that from the perspective of risk assets, the reasonable price range of bitcoin is $11000 to $25000. The price of $25000 has reflected the long-term acceptance of bitcoin by institutions, and the current price of more than $50000 is unsustainable
4. The proper bubble, bitcoin itself is of no use value, and no organization will endorse it. Therefore, its own value is 0
in terms of value preservation, he is not even as good as q-coin, at least there is a Tencent company endorsing q-coin
the sharp rise of bitcoin mainly comes from two aspects. One is that global criminal organizations such as drugs seek hidden currency circulation channels, which creates a "rigid demand" for bitcoin. The other is the international speculators
as we all know, hype is not a long-term thing. Any out of control hype in history will lead to a collapse. The black capital chain itself is the target of governments. Therefore, the foundation of bitcoin value is not reliable. This is more than anyone else's bubble
of course, some normal commercial institutions can also use bitcoins, but as currencies, they need stable currencies instead of such bulge. Therefore, its soaring value will lead to its withdrawal from the normal currency circulation. As a tool of value preservation and appreciation, bitcoin rarely gets long-term holding from large investment institutions (short-term holding is actually speculation)
