Loading is the work load that is allocated to a work centre. For example, time might be lost while changing over from making one ingredient of another. If the machine in time breaks down, it will not be available. If there is machine reliability data available, this also needs to be taken into account. Sometimes the equipment could possibly be awaiting parts to reach or be 'idling' for a few other reason. Other losses could include an allowance for the device being run below its optimum speed as well as an allowance for that 'quality losses' or defects which the machine may produce. Of course, many of these losses must be small or non-existent in a well-managed operation. Finite loading is definitely an approach which only allocates work to a work up to and including set limit. This limit will be the estimate of capacity to the work centre (based on the times designed for loading). Infinite loading is surely an method of loading work which does not limit accepting work, but rather tries to cope with it. From the total formula of capital, G- w-g, the surplus value is created in the process of direct production, which is also realized in the process of circulation. So, it seems to capitalist surplus value is the proliferation of all capital in advance, because (1) as for the cost of capital, in order to produce goods, he not only to advance capital to buy the Labour force, but also bought consumed in the process of production of a variety of means of production, these fees by capital purchase price as a factor of production to join the formation of the cost price; (2) in terms of the capital, capital purchased in advance of production and labor under the direction and supervision of the capitalists, in the process of production, play the function of the production of surplus value, not only the cost of capital is involved in the formation of the surplus value, and all the upfront capital as the material factors of production (including those not yet take fixed capital), in the whole process of production, to participate in the formation process of the surplus value, therefore, all the capital should be paid in advance. The residual value is not only the increase of the capital, but also the total capital increase. These are all distorted surface phenomena. In fact, the value of proliferation is just hired laborers in the process of production created the new value of the cost of living, the balance after deduct the labor price (wages), as the proliferation of alterable capital or hire workers free of charge for the rest of the product of Labour, is surplus value. The surplus value, as a product of the concept of total prepaid capital, is the transformation form of profit. Investors are confused and lost on the way forward, the confusion and bewilderment itself will keeps everyone to learn, so investors are eager to learn has been exist, is the power of the instinct of the profit will lead us to learn. It is not easy to learn the key question is: futures, its difficulty may not be less than the difficulty of the transaction, this kind of difficult to make a lot of people were forced to study only a period of time, that then is in a state of flow for a long time, but it is difficult to further more in-depth study. In theoretical economics, investment means buying (and therefore producing) capital goods - not being consumed but being used in future production. Examples include building railroads, or factories, cleaning the land, or allowing yourself to go to college. Strictly speaking, investment in formula GDP= C + I + G + NX is also part of gross domestic product. In that respect, the function of investment is divided into non-residential investments (such as factories, machinery, etc.) and residential investment (new homes). The correlation between I = (Y, I) is known to have a close relationship with income and interest rates. Higher incomes would boost higher investment, but higher interest rates would discourage investment because it would be more expensive to borrow. Even if companies choose to use their own funds to invest, interest rates represent the opportunity cost of investing in those funds rather than the interest that will lend out. Analysts are vehemently arguing that a sharp rise in the yield curve is a sign of a major shift in sentiment, or a temporary jolt from a position adjustment. Quality control indicators include: gasoline antiknock property (research octane number, motor octane number, antiknock index), sulfur content, vapor pressure, contents of olefins, aromatics, benzene content, corrosion, distillation range, etc. In January 2014, the national general motors (gm) IV standard was used. The state administration of quality supervision and inspection and the national standards commission issued the mandatory national standards for motor vehicles in phase V. The plan is to be implemented at the end of 2016. The sulfur content is the most critical environmental protection indicator in vehicle gasoline. In order to further reduce the emission of vehicle pollutants, the national V standard lowers the sulfur content limit from 50ppm in the fourth stage to 10ppm, which is 80% lower. Manganese has the potential risk to human health, and the vehicle emission control system will also have adverse effects. According to the principle of prevention, the limit value of the manganese content indicator is reduced from 8mg/L in the fourth stage to 2mg/L, which stipulates that no artificial addition is allowed. In order to further reduce the photochemical pollution caused by the evaporation of gasoline, and reduce the gas intake system of the automobile engine, the national five standard reduced the level of olefin from 28% to 24% in the fourth stage. Due to the decrease of octane number caused by the reduction of sulfur and manganese, the number of gasoline used in phase V was adjusted from 90, 93 and 97 to 89, 92 and 95 respectively. At the same time, considering the development trend of the automobile industry, the index requirements of motor gasoline are added in the standard appendices.
