Abstract: In the course of tesing technology on-line , owing to the frequency error , especially due to the curve rigidity effect , the calculated tension of cables has some errors .This paper introduces the method for correcting the tension of cables by using the principles of Least squares , and it also analyses its accuracy .The results verify that the modificatory technology of the natural frequency is right ;the tension of cables accuacy is better and the cables are safe

Key words: principles of Least squares , tension , frequency , accuracy evaluation
