常見例句雙語例句Based on the classical electromagnetic theory of Maxwell, the expression of the relative dielectric constant and relative magnetic permeability is deduced also;同時從經(jīng)典麥克斯韋電磁場理論出發(fā),推導出復相對介電系數(shù)和復相對導磁率的表達式;It is shown that radomes have the most optimized transmission performances if the relative permittivity of organic magnetic material equals to the relative permeability.數(shù)值結(jié)果表明,相對介電常數(shù)和相對磁導率相等的磁性天線罩具有最佳的電磁傳輸特性。The axial magnetic force increases with the increment of magnetic annular axial length and decreases with the increment of axial gap, radial off-centre or magnetic annular relative permeability.軸向磁力增加與增量磁性環(huán)形軸向長度和與軸向間隙,徑向偏離中心或磁性環(huán)形的相對磁導率的增量減少。zl50.com 返回 relative magnetic permeability
