由于复合氧化物中的阀金属元素的特殊性质，为保证处理液在工业生产中的稳定性，应尽量将阀金属阳离子单离子化，这样处理有如下好处：避免阳离子在水溶液中水解变性；便于处理液与腐蚀箔的浸润；尽量缩小晶粒尺寸。

The relationship between the CaOxa stones growth and the morphology of CaOxa crystals was discussed. The reasons why multicarboxylate such as citrates and tartrates were used as stone inhibitors in clinic were also discussed.

We note from the further studies that in the crystals, which sharing the similar crystal structures and coordinational environments, the magnitude of the Stokes shift of the luminescence of the dopant ion is in line with the average covalency of the replaced lattice site. This is because that the nature of Stokes shift is the energy transfer from the luminescent ion to the host lattice. The value of this energy is determined by the frequency of the host lattice in which the frequency is controlled by the chemical bond characters.

更深入的研究发现，在晶体结构和中心离子配位环境非常相似的系列晶体中，掺杂离子发射光的Stokes位移值与其所取代格位的平均共价性成正比的关系，这是由于Stokes位移的本质是发光离子在发光过程中向基质以光波辐射的形式传递能量，这一能量的大小是由基质的振动频率决定的，而基质的化学键性质恰恰决定着基质的振动频率。
