%X On the basis of the total least-squares(TLS) data processing theory and an iterative algorithm for TLS,first-order partial derivative of the nonlinear model was determined by using Taylor formula and the error magnitude of the results was derivated.The method was applied to the TLS precision evaluation,and the method for reliability testing is proposed.The experimental results verify the feasibility of the method in TLS precision evaluation.
