friction

• At any rate, friction always manifests itself as a force that opposes motion .
  总之，摩擦力总是表现为抗拒运动的力。
• The friction force is therefore called a nonconservative or a dissipative force .
  因此，摩擦力称为非保守力或耗散力。
• Afterwards they quarreled, which was a pity, and caused much friction .
  可惜的是，后来他们发生了龃龉，并引起了许多摩擦。
• When the friction force acts alone, the total mechanical energy is not conserved .
  当只有摩擦力作用时，总机械能就不守恒。
• Fillers include modifiers, extenders, plasticizer and low friction additives .
  填料包括改性剂，填充剂，增塑剂和低摩擦添加剂。
• The friction of n-butylstearate initially decreases with increasing temperature .
  N-硬脂酸丁脂的摩擦开始时随温度的上升而下降。
• Moving swiftly through the atmosphere, meteoroids are heated rapidly by friction .
  流星体在快速穿过大气层时，因磨擦而迅速加热。
• At any rate, but for friction our world would be very strange indeed .
  总而言之，要是没有摩擦力的话，我们的世界真会变得非常奇怪了。
• We try to remove or, at least, decrease friction in the working parts of our machines .
  我们要设法消除或至少减少机器活动部件的摩擦。
• That friction is more likely to be a molecular phenomenon closely associated with adhesion .
  摩擦很可能是与粘着力紧紧相连的一种分子。
