阻抗

This method is using two times conformal transformation method and mirror theory to calculate the characteristic impedance.

这种方法是采用两次保角变换结合同轴线特性阻抗公式进行特性阻抗计算。

We can also see that because damping factor is a ratio that requires the load impedance to compute, it must be stated against some known impedance to be meaningful.

我们还可以看到因为阻尼因子是一个比率值，而且需要负载阻抗已知才能够进行计算，所以阻尼因子必须和某一已知的阻抗同时具明才有意义。

"But if damping factor is a number derived from the speaker impedance, and speaker impedance dances all over the chart, how can damping factor just be a single number?"...

"但是如果阻尼因子是从扬声器的阻抗计算出来的数值，而且扬声器阻抗会在整个图表上跳舞的话，怎么有可能阻尼因子只是一个单一的数字？"。。。

Technically, the damping factor is the specified load impedance (in use, that'd be the speaker system) divided by the amplifier's output impedance.

技术上，阻尼因子就是指定的负载阻抗（实践中，也就是扬声器系统）除以放大器的输出阻抗。

The impedance of a probe-coil above a conductive plate with finite thickness was derived and expressed in series expansion,and then the impedance characteristics of the coil due to lift-off variation were analyzed.

推导了线圈置于有限厚度的金属平板上方时其阻抗计算的级数表达式，并以此为基础分析了由线圈的提离改变所引起的线圈阻抗的变化特征。

AC analysis shows lower electrochemical impedance and the diffusibility of lithium ion is clearly improved due to Y3+ doping.

交流阻抗测试结果表明， Y3+的掺入能降低材料的电化学反应阻抗和提高材料中Li+的扩散能力。

AC analysis shows lower electrochemical impedance and the diffusibility of lithium ions is clearly improved due to Y(superscript 3+) doping.

交流阻抗测试结果表明，Y(上标 3+)的掺入能降低材料的电化学反应阻抗和提高材料中Li的扩散能力。

This is called an impedance discontinuity or an impedance mismatch.

这被称为阻抗不连续或阻抗不匹配。

In this paper, a new medical impedance imaging modality (Magnetic resonance electrical impedance tomography-MREIT) is first introduced, including its mathematical theories and the reconstruction algorithms. Then its application in early breast cancer detection research is introduced in detail. Finally, its future research direction and major problems are summarized.

本文在此前提下介绍了一种高分辨率的医学电阻抗成像技术－磁共振电阻抗成像技术的成像原理与成像算法，然后介绍了MREIT技术在早期乳腺癌检测方向的应用，最后分析了该研究方向的发展前景以及目前存在的问题。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。

Increased appearance of lymphocele was noticed in patients with diabetic nephropathy, congenital malformations of the urinary tract, and inflammatory diseases, including glomerulopathy and extraglomerular ones, after high-voltage radiotherapy and after removal of the renal graft.

经过高压放射疗法和切除移植肾后，在糖尿病肾病患者、泌尿系统先天性畸形患者和炎症患者身上发现淋巴囊肿有所增加，包括肾小球病和球外疾病等。
