例句
- Use of a torque wrench for pulling on the nuts is suggested for actual bolt tightening.
在實際螺栓緊固時，建議採用一把扭矩扳手套在螺母上。 - At the same time, the relationship between screwing length and axial stress distribution of bolt screw thread is studied, which offers reference to the design of nut height.
文中還對旋合長度對螺栓軸嚮應力分佈的影響也進行了研究，為螺母高度的設計提供了參考。
