【Abstract】 A simple formula for calculating the furnace resisitance of graphitization furnace is developed.It is believed that the furnace resistance is a three-dimensional network electric resistance in nature and is comprised of a great quantity coduction resistance.The in-depth analysis about the dispersivity of the resistivity of the resistor grain and the initial furnace resisitance is conducted.Then the assembly average and standard deviation of the resistor grain are given under the same conditions of furnace charging.A method that can easily tell whether the furnace resistance is usual or not is presented.更多还原
