The results indicate that the concentration of P is less, the P atoms at grain boundaries are solid solution state and the influnce of Ce on the chemical state of P at grain boundaries is very small.
结果表明:当晶界P偏聚浓度较低,并以固溶态存在时,Ce对P的化学状态影响较小;当P的晶界浓度较高时,并以不同的化学状态存在时,Ce的影响较大,较多的Ce会改变P的化学状态。
补充资料：化学平衡状态
在一定条件下的可逆反应里，正反应和逆反应的速度相等，反应混合物中各组成成分的百分含量保持不变的状态。对化学平衡状态的理解，可用“逆”、“等”、“定”、“同”、“变”等5个字加以概括。逆：指化学平衡的研究对象是可逆反应。等：指正、逆反应速度相等，表明化学平衡是一种动态平衡，反应并没有停止。定：指反应混合物中各组成成分的百分含量一定，它是正、逆反应速度相等的必然结果。同：指在相同条件下，可逆反应不论从正反应开始进行还是从逆反应开始进行，可达同一平衡状态。变：指外界条件改变时，平衡状态可能发生改变，即平衡发生移动。
