Abn amro believes that after a strong 2017, precious metals will face many headwinds at the start of 2018. The bank said rising dollar and bond yields would put downward pressure on gold and silver prices in 2018. Gold is expected to trade between $1,200 / $1,250 an ounce next year. Think the dissipative structure theory, the negative entropy is to maintain and develop dissipative structure in the process of ordering "power", only the negative entropy flow to the system input, to offset the internal entropy, generated by the block system to the direction of a disorderly change, in order to maintain and develop ordering movement of the system. Obviously, this view only looks at the ordering process of dissipative structure from the perspective of pure "energy exchange". However, the nature of the material in addition to the energy the most basic characteristics, but also has many other features, such as physical properties, chemical properties and biological characteristic, social characteristic, the information characteristics, the material properties of the energy as long as the organization and cooperate well, can be used to promote the human survival and development, to maintain and develop human ordering, played the same energy orderization and objectively, and can according to the main body of the objective need of ordering energy converted into a number of standards, the dissipative structure of the ordering process is not only determined by the energy exchange, must also be by "material exchange" and "information exchange". It can be seen that some non-energy forms of the generalized preordering energy can be attached to the ordering energy and indirectly affect the preordering degree of the dissipative structure. Cave although not directly provide food for animals, for example, energy, but it can be for animals from the cold in winter, make animals reduce body heat loss, and reduce the disease incidence and mortality of animals, the objective effect and reduce the loss of food energy, improve the body of food energy use efficiency. Obviously, these not energy in the form of "ordering energy" from the objective effect does play a orderization and energy is exactly the same effect, also can promote the development of the dissipative structure ordering, plays an alternative on features, compensation, strengthen, catalytic, extension, ordering the role of energy, is a kind of indirect power energy. On the basis of "dissipative structure theory", the concept of unified axiology is put forward. But the DRAM and NAND semiconductor industries have gone from boom to bust in the face of rising prices and the abundance of falling prices. Will it be any different this time? Or is the need for mobile device memory and disk replacement sufficient to continue to delay the abundance until the foreseeable future?
