| 5. | As a result , analysis and discussion show that the influence of interfacial crack or rigid line inclusion on the interaction between screw dislocation and inhomogeneity is significant
分析结果表明，界面裂纹和刚性线夹杂对螺型位错与夹杂的干涉作用具有强烈的扰动效应。 |
| 6. | In addition , the growth mechanism of c - axis was screw dislocation growth or rough interface growth , but that of a , b - axis was two - dimension nucleation growth . because in low supersaturation , the speed of helix dislocation growth and rough interface growth was higher than that of two - dimension nucleation growth
另外，由于羟基磷灰石晶体结构的特点， c面主要以螺旋位错生长和粗糙面生长两种机制为主，而a 、 b面则主要以光滑面的二维成核生长为主。 |
| 7. | When the radian of rigid line reaches extensive magnitude , the presence of interfacial rigid line inclusion can change not only attraction force on dislocation arisen by soft inhomogeneity into repulsion force , but also the interaction effects between screw dislocation and soft matrix . soft inhomogeneity can repel screw dislocation in piezoelectric material due to their intrinsic electromechanical coupling behavior
当界面裂纹达到一定弧度时，可以将硬夹杂对位错的排斥作用改变为吸引；当刚性线夹杂达到一定弧度时，不但可以将软夹杂对位错的吸引改变为排斥，也可以改变软基体对位错的作用性质。 |
| 8. | Applying perturbation technique , the image force on dislocation is obtained when dislocation located arbitrary point either outside or inside inhomogeneity , however , a number of previous related investigations on above problems only calculated the interactive dislocation force as the dislocation lies on the x - axis . the variation of screw dislocation forces for correlative material parameters and different radians of crack or rigid line is discussed particularly
针对以往大多数相关文献~ ( [ 7 ] - [ 16 ] )只求出了位错在x轴上时位错力表达式，本文应用扰动技术，导出了位错在基体或夹杂中任意点的位错力公式；并讨论了位错力随材料相关参数，裂纹或刚性线弧度的变化规律。 |
