In the surface analysis and the manufacture of photocathode the cesium ion source shows some advantages as compared with the neutral cesium source.

在光电阴极的制备及对光电阴极作表面分析中，铯离子源较中性铯源具有一定的优点。

The investigation indicates that rare earth elements have effect on the cesium ion exchange capacity, but hardly influence the distribution coefficient for cesium ion on Cs IS.

稀土元素对提铯离子筛的铯离子交换容量有一定的影响，但对铯离子分配系数影响不大；

It uses two ion exchange processes to remove the radioactive elements Cesium-134 (Cs-134), Cesium-137 (Cs-137) and Strontium-90 (Sr-90) from the seawater.

The first is a bulk removal, ion exchange process in which sodium is swapped for cesium or strontium within an inorganic, crystalline structure.
