Chapter 1 narrated the phylogeny and status quo of eit and the significance of this project mainly 本文第一章主要讲述了国内外关于电阻抗断层成像研究的现状和本课题研究的意义等内容。
Current density in tissue , that is , the intensity of hf current per unit of area , is even more important than electrical resisance 组织中的电流密度（也就是流过每单位面积的高频电流强度）甚至比电阻抗更重要。
Hf - current generates warmth in tissues . this warmth rises proportionally to electrical resistance and superproportionally to the square of current density 高频电流流过组织时产生热量,这些热量和电阻抗、电流强度的平方成正比。
Pertaining to elements of electrical impedance concentrated in discrete units rather than being distributed over transmission lines or through space 用于修饰或说明电子元件,其电阻抗集中在各个分立的器件中,而不是分布在整个传输线路上或按空间分布的。
