Abstract:
A structural parameter analyzing apparatus comprising:a structural parameter setting unit for setting a structural parameter;a data input unit for inputting a measured value of a sample;calculated value calculation means for determining a calculation value corresponding to the measured value according to the structural parameter from said structural parameter setting unit;first logarithmic conversion means for making logarithmic conversion of the calculated value;second logarithmic conversion means for logarithmic converting a value of the measured value subtracted by a background strength;sum total calculation means for squaring a difference between the two logarithmic conversion values obtained by said first and second logarithmic conversion means to obtain a sum total s;a determination unit for determining a minimum of a plurality of sum totals s obtained by said sum total calculation means by varying the structural parameter; andan output unit for outputting a structural parameter of the minimum sum total.
