| 摘 要： | 任何复数均可利用指数形式表示。可以证明,其模值与相位之间存在着可以相互转换的关系。本文从付氏变换出发,推导出频率域复数电磁场的模值与相位的关系式,并给出其易于进行数值计算的形式。通过引入单位相位的概念,使得将模值数值转换为相位成为可能。本文还讨论了数值转换的精度及其在频率测深中的应用问题。

| Abstract: | Any complex can be expressed in the form of exponent. It can be proved that certain relation exists between the amplitude and phase.Starting from Fourier transform, the formula exhibiting this relation can be got, and the formula suitable for numerical calculation has also been shown here.By introducing the concept of element phase. It is possible to transform the amplitude into phase.The precision and application has also been discussed. |
