...而镍层中的磷不参与合金反应，因此多余的磷原子则会留在镍层和合金层界面，过多的P在镍和IMC界面富集将形成黑色的富磷（P-Rich）层，同时，存在的镍层腐蚀会影响焊料与镍层的结合，富磷层和镍层腐蚀的存在会降低焊点与焊盘之间的结合强度；当焊点在组装过程中...

该金属屏蔽层含有磷，且具有含磷率大于其它部分的富磷部位。
The barrier metal layer contains phosphorus, and includes a phosphorus-rich portion where the phosphorus content is higher than that at other portion.
富磷锆石是岩浆高度演化的结果，可以看成是高磷花岗岩的一种特征矿物。
The P rich zircon is the product of a highly evolved magma, and is might be one of the important characteristic minerals in the high P granite.
随着提高加热温度和延长保温时间，“上坡扩散”的富磷层深度和浓度将不断增加。
With increase of heating temperature and duration of heating time, the depth and concentration of phosphorous-enriched layer in uphill diffusion increases continuously.
