剩磁比 的英文怎麼說
中文拼音 [shèngcíbǐ]
剩磁比
英文
remanence ratic-
The finer the grain is, the higher the magnetic properties are, such as the improvement of coercivity. according to the theory of remanence, the intensity of remanence is in direct proportion to the density of magnet and ms. the improvement of remanence resulted from the interaction of density of magnet and ms, but the ms took the more important role
究其原因：晶粒的細化可以提高磁體的矯頑力；而根據剩磁的理論公式，剩磁與磁體密度和飽和磁化強度成正比，剩磁的提高是磁體密度和飽和磁化強度的提高的綜合效果，但其中飽和磁化強度的提高佔主導地位。With the increasing of the doping amount of these four rare earths, both the specific saturation magnetization and the specific remanent magnetization decrease gradually to the same extent

為了進一步抵消剩餘磁通，提高互感器的精度，提出了一種並聯電容線圈補償零磁通的方法，並進行了理論推導，設計了基於該方法的100匝電流互感器，通過校驗證明它可以改善零磁通電流互感器的比差和角差特性，提高互感器的精度，將電流互感器的二次匝數由普通互感器的幾千匝降到了100匝，提高了測量微小電流的能力。X - ray diffraction results revealed that the structure of as - deposited smco film was amorphous and crystallization happened after the films annealed at 500 in vacuum. the magnetic tests of smco thin films showed that its coercivity reduced with the increase of film ' s thickness while the ratio of mr / ms was opposite. the films " coercivity and mr / ms declined after it annealed at 500 because the machanism of magnetization were changed from domain wall nailing into magnetic nuclear forming
研究結果表明，由於雜質fe的摻入降低了smco薄膜的磁性能；制備態smco薄膜為非晶態結構，矯頑力hc隨著薄膜厚度的增加而減小，剩磁比mr ms隨膜厚增加而增加；經過500真空退火熱處理后，薄膜出現smcos的結晶物，矯頑力hc降低， mr ms減小，磁化機制由疇壁釘扎類模型轉為形核類模型。Ii. hc and mr / ms rise with the extension of time, which also because the fcc texture changes into fct texture
（二）隨著熱處理時間的延長，矯頑力和剩磁比顯示出與（ l ）相同的變化趨勢，其解釋也是同樣的。The highest hc and mr / ms are obtained when c thickness is 10a. iv. hc decreases with the increasing of film thickness from 600a to 1400a
（ 4 ）薄膜的厚度在600 1400人的范圍內，隨著厚度的增加，矯頑力呈現降低的趨勢，而剩磁比的變化並不明顯。I. hc is greatly improved from several oe to nine thousands oe with the rise of annealing temprature, but mr / ms decreases, which mainly because fcc texture changes into fct texture
熱處理溫度在600 850的范圍內，隨著的溫度的升高剩磁比稍有降低，主要原因是晶相結構的形成和fcc相到fct相的轉變。The particle size of the product is about 16 nm with perfect crystal structure. the product exhibits superparamagnetism and strong magnetic responsivity, the saturation magnetization being 55. 4emu / g and the magnetic susceptibility being 8. 28 10 - 3emu / oe. the particle size distribution is homogeneous with good dispersion. 2
