The result is a smoother surface, lowercontact stresses and an increase in service life.
结果是表面更为平滑、接触应力降低和使用寿命延长。
2
Their high torque ratings permit use of smaller diameter units which lowercontact velocity on high speed applications.
其高扭矩比率允许使用较小直径的单位联连接速度较低的高速应用。
3
Members of highly ranked groups can be polluted by coming into contact with bodily secretions, particularly saliva, of individuals of lower-ranked castes.
