Structural fissures are further divided into five sub - types , with mesh and high angles fissures being dominant 构造缝可进一步分为5种类型,以高角度缝和网状缝为主。
Moreover , the diffraction peak shifts toward high angle as sr content increases . it is ascribed to the substitution of la3 + by sr2 + in lscf increases the average radius of a ions and causes a charge imbalance 且随着sr含量的增加,衍射峰值向高角度方向稍有偏移,这是由于低价sr ~ _ ( 2 + )取代高价la ~ ( 3 + )增加了a位离子的平均半径,同时引起电荷不平衡。
