介绍螺栓在施加压缩载荷的同时，采用拧紧力矩的方法来测定摩擦系数，再依据这一摩擦系数控制预紧力．此方法在螺栓拧紧过程中测定摩擦特性，而不降低拧紧效率．
Introduction Bolts apply a compressive load at the same time, the method of tightening torque to determine the friction coefficient, and then control the pre-tightening force based on this coefficient of friction. This method determines the friction characteristics during bolt tightening without reducing the tightening efficiency.
