This paper mainly discusses the upper semi-continuity of G-proper effective solution mapping for multi-objective optimization.

The effective calorific value,composition and thermal stability of the smelting coal are all important for the COREX process,because they can influence the smelting process by influencing the coal consumption,the utilization rate of reduction gas,and the height of the fixed b.

Coal consumption of COREX is too much and coke is still used to supply effective calorific value of coal and form a fix bed with carbon.

A new measurement for alternating-current virtual value is presented.

According to the principles of numeration table, the author puts forward simple but practical methods of how to measure the mean values, virtual values and peak values of non sine waves.

The AC voltage meter and the AC current meter used in power system are usually rectifying instruments, which adopt principle of responding to the average value of voltage and current and get the virtual value by using of the proportion between the average value and it.
