adjusted net profit calculation As of December 15, the number of gasoline stocks in the EIA increased by 12.37 million barrels, an increase of 173.28 million barrels, and the previous value increased by 566.4 million barrels. As of December 15, the EIA refined oil depot increased by 769 million barrels, or 14.56 million barrels. In the week ended Dec. 15, the U.S. government said an increase of 754, 000 barrels of U.S. crude oil inventory in Cushing, Oklahoma. "Manufacturing companies with complex and lengthy international supply chains, such as the automotive industry, could also face significant challenges. These developments could also have a significant impact on productivity growth. " According to the travelling expenses data, in mid-december in zhejiang market price of R22 / everything/R410a 1.53/2.57/36500 yuan/ton, respectively, from early September at the bottom of the periodic rebounded 20% / 38% / 46% respectively, the downstream demand off-season, but the price of raw material hydrofluoric acid, chloride methane due to higher environmental factors superposition enterprise starts ascending space limited (according to the travelling expenses, effective device industry starts. Seventy percent), refrigerant price off-season does not light. Moreover, the average price of r22/r22/r134a/R410a has increased by 68%/32%/103%, respectively, from 2016Q4. Compared with the raw material spread, we have been able to calculate the company's overall profitability. In just three days, the 30-year bond jumped 16 basis points, the biggest gain since December 2008. 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. In economic terms, the benefits of holding any two currencies should be equal in the equilibrium of the foreign exchange market, which is: Ri=Rj (interest rate parity). Here, R stands for yield, and I and j represent currencies of different countries. If the benefits of holding two currencies are unequal, you will have A arbitrage: buy A kind of foreign exchange and sell B foreign exchange.
