Because consumption strongly relies on the composition and performance of material of mould powder for thin slab casting, the experiment measures the melting temperature, surface tension and fluid length of mould powder by regulating the content of Li_2CO_3, NaF, Na_2CO_3, CaF_2, cryolite and the basicity of mould powder, in order to study the relationship between the composition and performance of material and the consumption of mould powder for thin slab casting.
According to the econometric results ,It is shown that ,using the data of GDP and the intensity of steel consumption in China,we can carry on a more accurate short forecast to the total amount of the steel market demand,the apparent volume of china’s steel consumption will arrive at about 0.34 billion tons in 2005;
there is a long-term cointegration relation between the apparent volume of the steel consumption with the investment in fixed assets,therefore,we can use the data of investment in fixed assets to forecast the total amount of the steel market demand in a long term, the apparent volume of china’s steel consumption will arrive at about 0.44 billion tons in 2010;
A direct method in optimal portfolio and consumption choice
In this paper, we use a direct method to solve the optimal portfolio and consumption choice problem in the security market for a specific case, in which the utility function is of a given homogenous form, i.e.
An optimal investment/consumption problem with higher borrowing rate
In this paper, optimal investment and consumption decisions for an optimal choice problem in infinite horizon are considered.
this paper gets the optimal consumption and optimal investment in the form of with .
