Abstract
The present review systematizes the equations relating the intensity o f fluorescence with the composition of the radiator (the ct equations) . The techniques for on of the influence coefficients are described an d the procedures accounting for the dependence of the coefficients on the sample composition are compared. The accuracy of analysis is shown to correlate with the validity of the approximation C(i) = f(I(i)), which is used to find the desired content as order approximation.
