激光可以改变这种局面,从而使同位素分离变得比较容易 、 比较廉价一些.

Lasers promise to change this by making <em>isotope</em> <em>separation</em> easier, and cheaper.

利用具有中间共振能级的无多普勒双光子相干选择激发来提高激光同位素分离的选择性和激发速率。

Selectivity and excitation rate of laser <em>isotope</em> <em>separation</em> can be enhanced by using the coherent selective Doppler-free two-photon excitation with intermediate resonant level.

一种液相级联的精馏塔，属于同位素分离、精馏设备技术领域。

The utility model relates to a rectification tower in a liquid phase cascade, which belongs to the technical filed of isotope separating and rectifying facilities.

不过, 也正因为这样, 要把某一元素的各同位素分离开来,就可能是极其困难的事,要付出很高的代价才能办到.

For that reason, however, separating the isotopes of an element can be exceedingly difficult and costly.
