瞬变记录仪技术与精确的高分辨率电流放大器一起提供了一种在超低频段内获得复介电常数ε~*(ω)的数据的简单方法。常见的在超低频段内的复介电常数ε~*(ω)是采用与傅里叶变换法结合起来的直流瞬态特性方法进行测量的,把这些结果与用超低频电桥法观测到的结果相比较,往往出现不一致 Transient recorder technology, along with a precision high-resolution current amplifier, provides a simple way to obtain data with a complex permittivity ε ~ * (ω) in the ultra-low frequency range. The common complex dielectric constant ε ~ * (ω) in the ultra-low frequency range is measured by the DC transient method in combination with the Fourier transform method. These results are compared with those observed with the ultra-low frequency bridge method Compared to the results, often inconsistent
