The cross spectrum expression of energy flow is deduced when two linear accelerometers are arrayed to measure energy flow.
测量结果表明，在极低速状态下，仪表齿轮齿面间的摩擦系数几乎与齿面间的作用力无关，但随齿面相对滑动速度的增加而线性增加。
Results show that the frictional factor almost has nothing to do with applied forces, but increases linearly with the sliding speed between the tooth faces.
