但晶胞常数，衍射峰的数目和强度却发生了变化。

But cell constant, diffraction site and intensities have been changed.

射线衍射表明，其主物相仍然是六方晶系的微晶镁，晶胞常数与微晶镁相同。

XRD indicated that the main phase of the resulting microcrystalline Mg remained the hexagonal crystal structure and the lattice constants keep the same values with the pure microcrystalline Mg.

同时，随着Y3 +取代的增加，晶胞常数减小，介电性能随结构的变化而呈现有规律的变化。

Simultaneously with increasing of Y3 + substitution, crystal cell constant was minished. The dielectric properties were changed regularly with the change of structure.
