The introduction of Pt buffer layer can also raise the coercivity in sputtered Co-Pt alloy films but the Pt films must have good FCC (111) texture. The analysis of XRD and TEM shows that there exists ordered CoPt〓 Ll〓 phase in Co-Pt alloy films.

Pt缓冲层的引入可以进一步提高溅射Co-Pt合金膜的矫顽力，但Pt膜必须具有良好的FCC（111）织构。X射线和TEM研究发现在Co-Pt合金膜中存在有序的CoPt〓 Ll〓合金相。

Due to the most of particle size are smaller than critical particle diameter Dp at 1 nm CoPt, the effect of superparamagnetism causes the decrease of coercivity. Approximately, the orientation of magnetic easy axis of CoPt thin films is random.

当CoPt厚度为1 nm时，由於大部分的颗粒尺寸小於临界直径Dp，因此产生超顺磁效应，造成整体薄膜之矫顽磁力的下降，大致上，於700℃退火30分钟之CoPt单层薄膜的易磁化轴方向呈现random orientation。

From TEM bright field image, it can be seen that the surface image of CoPt formed discrete islands, and gradually change to continuous film as the CoPt thickness increase. After annealed at 700℃ for 30 minutes, the single domain state is found by the observation of MFM images at 7.5 nm CoPt. At single domain state, the variation of coercivity with particle size agree with the theory of single domain particles.

由TEM平面明视野影像可以看到，随著CoPt厚度的增加，其表面型态由不连续岛状结构逐渐转变为连续膜，从MFM图可以发现於700℃退火30分钟之CoPt(7.5 nm)为单磁区状态，在此单磁区状态其矫顽磁力随颗粒直径的变化符合单磁区理论。

By using both the hydrogen decrepitation and double-alloy processes to avoid soft magnetic Laves phase,we prepared N35AH sintered Nd-Fe-B permanent magnet with ultra-high coercivity,which can be used at temperature up to 240℃.

现在汽车驱动电机、水力风力发电机、压缩机电机、船舶用大功率推进电机等领域对高使用温度烧结Nd-Fe-B磁体的需求日益增长，所以提高烧结材料的耐热性成为当今钕铁硼行业的主要研究方向之一。

The content of magnetic coercivity components is closely related to the content of the ferromanganese concretion.

铁锰结核含量高的样品，中磁组分、硬磁组分含量也高，而软磁组分含量低，与此对应的是这类样品的磁化率低。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
