矩

• A matrix of this sort occurs, for example, in electric networks when mutual inductance is present .
  例如，当电网络中有互感时，就会出现这种阵矩。
• Bending moments produced by lift generally have only a small effect on the resultant bending moment .
  一般由升力所产生的弯矩对最终的弯矩只有很小的影响。
• Any heteronuclear diatomic molecule must have a dipole moment since its two ends are different .
  任何异核双原子分子必然具有偶极矩，因为它的两端是不同的。
• A torque of this kind, arising from a pair of equal and opposite forces, is sometimes called a couple .
  由一对相等而相反的力产生的这类转矩，有时叫做力偶。
• As can be seen by reference to eq. (4. 1. 3), a couple has the same moment about all points .
  正如依据式（413）可看到的那样，力偶对所有点之矩都是相等的。
• An explanation of the magnitude of such a dipole moment must seal explicity with two contributing factors .
  对这和偶极矩大小的解释必须明确研究两个有关的因素。
• The interaction forces that may be present among the particles of a system give rise to internal torques .
  系统内各质点间可能存在着的相互作用力，会产生内力矩。
• The two-moment description tells where the ions are located and roughly how broad the distribution is .
  二阶矩描述给出了离子的停止位置，并粗略地给出分布的宽度。
• For a rigid body rotating about a principal axis, the angular acceleration is related to torque by t =ia .
  对于绕主轴转动的刚体来说，角加速度与转矩的关系是TIa。
• Torsional microslip at the clamps results in spurious torques which act like pivot friction torques .
  夹紧处扭杆的微小滑移会产生干扰力矩，它的作用和轴颈的摩擦力矩一样。
