氧化物颗粒 meaning in Chinese
oxide particle
Examples
- In the ingots the particles of rare earth oxide are dispersive distribution
在坯条中，稀土氧化物颗粒为弥散分布，稀土的强化机制为弥散强化。 - During the heating process the fibers of rare earth oxide break and become the spheral particles progressively
在热处理过程中，纤维状稀土氧化物颗粒断裂，并逐步聚集成短棒状或球状。 - Usually , they are stretched step by step and form the fibers fmally , but the y2o3 particles ca n ' t form the fibers and just smash
多数情况下稀土氧化物颗粒被逐渐拉长成纤维状，但氧化钇颗粒破碎成颗粒而不形成纤维状。 - Therefore , the strenthening mechanism of rare earth is dispersive atrenthening . the particles exist not only on the boundaries but also in the grains
稀土氧化物颗粒不仅存在于晶界上，也存在于晶粒内部，晶粒内部的稀土颗粒粒径比晶界上的颗粒小。 - These particles will aggregate into a certain structure when the applied field yields a critical value . the other is fabricated from " half - metallic " oxides , i . e . , ferromagnetic oxides which are predicted theoretically to be completely spin - polarized and really found experimentally to have very high spin - polarization . when a magnetic field is applied to half - metallic granular systems , the resistance will drop rapid and dramatically , which is called the extrinsic magnetoresistance effects in half - metallic granular systems
在磁性材料中，亦有由在理论上具有完全的自旋极化率、在实验中也被证实具有高自旋极化率的一系列半金属氧化物材料构成的多晶、粉末等颗粒体系，被发现能在外磁场下发生显著的电阻下降，即半金属氧化物颗粒体系中的外禀磁电阻效应。
