摩擦系数的选取是件麻烦的事情,必须得小心考虑实际工况
--(Extreme care is needed in using friction coefficients and additional independent references should be used. For any specific application the ideal method of determining the coefficient of friction is by trials. A short table is included above the main table to illustrate how the coefficient of friction is affected by surface films. When a metal surface is perfectly clean in a vacuum . the friction is much higher than the normal accepted value and seizure can easily occur. )
