| 7. | 7 ) by using in - situ hydrothermal synthesis and sol - gel complex method a stoichiometry tetragonal perovskite pbti03 ceramic film was successfully prepared on tini substrate
通过采用原位水热solgel复合合成法，在tint基体上成功制备了结构较为致密的pbtio 。 |
| 8. | No evidences of low - temperature phase transition were found for pbtio3 , while the tetragonal - orthogonal and orthorhombic - rhombohedral phase transitions were present for batio3
没有发现钛酸铅存在低温相变的证据，而钛酸钡则存在四方正交和正交三角铁电相变。 |
| 9. | In the orthorhombic phase , the desorption activation energy has an obvious increase with the increase of temperature , while it varies smoothly in the tetragonal phase as the temperature increases
当样品为正交相时，脱附活化能随着温度的升高明显增加，而四方相时则变化比较平缓。 |
| 10. | The xrd peak of 2 6 = 45 ? was gradually widened with the increasing of pt . it might mean that rhombohedral phase was gradually converted to tetragonal phase in this system
在pmn - pt系统中，随着pt含量的增加， 2 = 45的xrd特征峰出现明显峰宽化现象，表明pmn - pt由三方相逐步向四方相转化。 |
