Three precautionary measures to prevent natural gas hydrates in pipe from blocking are put forward, that is, not to used bending pipe if possible during construction stage ; increasing pigging frequency before pipeline commissioning to elimninate water within pipe ; injecting inhibitor in regular way
提出了三項預防水化物的措施：施工階段避免過多使用彎管；投產前增加吹掃次數，徹底清除水；運行初期定期注入抑制劑。 -
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。 -
Based on the exact solution of the static nonlinear bending problem which is given in reference [ 2 ], the characteristic relation between the natural frequency and the static load is gained by means of the modified iteration method
靜平衡問題採用文獻[ 2 ]給出的精確解，在此基礎上用修正迭代法求解，得到了其固有頻率載荷特徵關系。 -
Testing of paper and board - determination of the bending stiffness - part 1 : length of natural frequency method
