经典

• It establishes an absolute energy, removing the classical arbitrariness of the zero of energy .
  它规定了绝对能量，排除了经典的能量零点的任意性。
• So far we have implicitly treated the electron as if it were a classical particle .
  直到目前为止，我们一直隐含地把电子当作一个经典粒子加以处理。
• In fact, we had no reason to expect complete identity of classical and quantum mechanical forms .
  事实上我们也没有理由要求经典形式同量子力学的形式完全一致。
• Classical mechanics and electromagnetism were inadequate to explain the motion of electrons with the atom .
  经典力学和经典电磁学不足以解释电子在原子内的运动。
• Forces, in the classical sense, are envisioned as due to the exchange of quanta of the field in question .
  经典意义下的力被看成是由于交换有关的场量子而产生的。
• Quantum mechanics showed classical mechanics to be incorrect for describing the internal motions within atoms .
  量子力学证明，用经典力学描述原子内部的运动也不正确。
• Bohr developed his theory using three concepts, all of which were at variance with the classical theories .
  玻尔在发展他的学说时用了三个概念，都是与经典理论相矛盾的。
• The classical analog of this state of motion is a straight-line trajectory back and forth through the nucleus .
  这个运动状态的经典对应，是通过原子核来回运动的直线轨道。
• In comparison with the classical lunar theory the motion of an earth satellite offers important practical differences .
  与经典的月球理论相比较，地球卫星的运动有显著的实际差别。
• One can make a plausible guess as to how to get the proper equation for quantum mechanics from classical mechanics .
  我们可以似乎合理地推想如何从经典力学得到量子力学的适当方程。
