To reach the ground state, physicists had to cool their beams to nearly absolute zero. They also had to make the quanta as large as possible by making a beam stiffer to increase its frequency.
为了实现真正的基态，物理学家不得不将光束冷却到接近绝对零度，他们还要通过使光束保持静止来增大其频率，让量子尺度变得尽可能大。
If there is no the sun radiation, the ground temperature will quickly reduced to near absolute zero.
如果没有太阳光的照射，地面的温度将会很快地降低到接近绝对零度。
If there is no the sun radiation, the ground temperature will quickly reduced to near absolute zero.
