Over the past decade,the laser cooling and trapping of atoms technology has been well developed,and in a variety of forms.

十多年了，激光冷却和俘获原子的技术得到了充分的发展，出现了各种各样的形式。

Since the neutron is uncharged, it is not affected by the charged electrons and protons of the target atom, and is therefore more likely to be captured than any other particle, provided that it is in resonance with an energy level of the nucleus.

由于中子不带电荷，所以不受带电粒子和靶原子的质子的影响。而且，如果中子同核的能级协调一致，就会更易于被其他任何粒子俘获。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
