The cable sag and bending stiffness effects are studied on the higher natural frequencies of cable vibration. it is found that the differences of the higher adjacent frequencies go to the fundamental frequency of the taut string theory even though the cable sag or bending stiffness is included. this unique characteristic of cable vibration is used to determine the cable tension with the well - known taut string theory
2 .考慮垂度和抗彎剛度對高階自振頻率的影響，探討了索相鄰頻率之差，發現索的高階頻差就是弦振動理論的基頻，利用這一特性，分析了頻差法測索力的精度和適用范圍。 -
