a位 meaning in Chinese
asite
position a
Examples
- Block a sequence of bits of fixed length
定长的块a位序列。 - 4 . magnetism study on we presented a detailed study of dy - doping effect on magnetism
第四章研究了a位第二类稀土元素替代对锰氧化物磁性的影响。 - Moreover , the diffraction peak shifts toward high angle as sr content increases . it is ascribed to the substitution of la3 + by sr2 + in lscf increases the average radius of a ions and causes a charge imbalance
且随着sr含量的增加，衍射峰值向高角度方向稍有偏移，这是由于低价sr ~ _ ( 2 + )取代高价la ~ ( 3 + )增加了a位离子的平均半径，同时引起电荷不平衡。 - The investigation of structure by x - ray diffraction shows that crystal parameters changes clearly when percenting ca and la into pbtio _ 3 , it was caused by the ca ion and la ion replaced the pb ion of a position in perovskite compound , that bring lattice mismatch and asymmetrical replace
在pbtio _ 3中掺入la和ca可以有效改变薄膜的晶格常数,这是因为在abo _ 3型化合物中,钙离子、镧离子取代了a位的铅离子,造成晶格失配和不对称取代。 - However few existed in nature . many of the multiferroelectric magnetoelectric material have been synthesized by two phases for the purpose , and many of the research have always been concentrated on the substitution between the a - site cation ln and other metallic ions effect on the properties
这些材料很少存在于自然界中，为了达到这种效果，大多可以利用两相混合烧结获得，且主要就钙钛矿结构相中a位离子ln与其它金属离子的取代及对性能影响进行研究。
