功

• The minus sign indicates that the work done by the force decreased the kinetic energy of the neutron .
  负号表明这个力所作的功降低了中子的动能。
• Heat, like work, is more a name for an energy currency than a name for a "real" energy .
  热同功一样，与其说它是“实在的”能量，不如说它是能流。
• We now equate this work to the total change in energy, kinetic and potential, of the element .
  现在我们使这个功等于流体无动能和热能的总能量的改变。
• An internal work product will occur when a bar force, n. is associated with a change of length, e .
  当杆件内力N和长度的变化e相结合时就得到内乘积功。
• The results which easily be duplicated in one laboratory, sometimes are not reproducible in another .
  一个实验室能顺利地复制而有时另一个实验室则不成功。
• Thus, the total work done during a loop displacement returning to the starting point is always zero .
  于是，在返回出发点的一闭路位移中所做的总功必为零。
• We shall use the symbol w without any subscript to denote work done on the system by its surroundings .
  我们将用不带任何注脚的符号W表示环境对体系作的功。
• The darter had sounded the alarm and drawn first blood, but its day was done .
  这一次是“飞鱼号”发出警报，立下了第一功，但是它光辉灿烂的日子随着结束了。
