MIXING STATE DETERMINATION METHOD FOR DETERMINING MIXING STATE OF POWDER MIXTURE, MIXING STATE CALCULATION DEVICE, MIXING RATIO CALCULATION DEVICE CONTROL PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method for determining the mixing state of a powder mixture, relative to a large amount of a sample used as a measuring object.;SOLUTION: In this mixing state determination method for determining the mixing state of the powder mixture, the powder mixture is formed by using the X kinds of powders; and simultaneous equations to the number of X are formed from the (X-1) kinds of physical property values having a proportional relation to the mass of the powder, the mass of a part of the powder mixture formed by mixing the X kinds of powders with a prescribed mass ratio, and the (X-1) kinds of physical property values, in proportion to the mass of the part of the powder mixture, and by solving the equations, the mass ratio of the X kinds of powders in the part of the powder mixture can be calculated. As a result, by comparing the result with a prescribed ratio with which the powder mixture is mixed, the mixing state of the part of the powder mixture can be determined.;COPYRIGHT: (C)2009,JPO&INPIT
