- For the samples with x>0.11 after crystallization, a tetragonal phase Y_2Fe_(14)B appears, which will harden the previous magnetic properties. Under optimum annealing temperature and huration, the maximum H_c for x=0.25 can reach to 4.6 kOe. 当样品晶化后;对x>0.;1的样品出现四方相Y_2Fe_(14)B;使原耒的软磁性硬化;当x=0
- At the same time, the larger porocity, the smaller bore, the evener porocity and the more tetragonal pHase amounts of coatings were, the more excellent thermal cycling performance was. 同时，涂层的孔隙率越大，孔尺度越小、分布越均匀、所含四方相越高，则涂层的抗热震性能越好。
- The tetragonal phase of PbTiO3 is very stable owing to its large tetragonal strain, and relatively small tetragonal stain of BaTiO3 is an important reason for its low-temperature phase transition. 由于钛酸铅具有较大的四方应变，使得其能够在四方相稳定下来，而钛酸钡较小的四方应变是其仍能够发生低温铁电相变的一个重要原因。
- It was ascertained that the addition of MnO and CoO did not cause a remarkable change in crystalline structure, with the specimens remaining the coexistence of rhombohedral and tetragonal phases. 研究结果表明，添加MnO和CoO对材料的晶体结构未产生显著影响，各组分样品保持三方-四方共存结构。
