[求助] 英译汉一小段

请高手帮忙:

  An alternative method of determining the site impedances is to calculate an impedance estimate for each time-frequency element. This gives an estimate of the instantaneous impedance for any spectral frequency at any time. The total impedance map can therefore be referred to as an ‘evolutive impedance’, just as a TFD spectrum is referred to as an evolutive spectrum. Since the impedance is a site function and is expected to be constant for the recording time, the instantaneous impedance estimates in any spectral frequency can be statistically reduced to a single impedance estimate equivalent to that produced by the stationary analysis of a stationary M T data set.Due to its robustness to non-normal distributions and outliers, the median was used to estimate the impedance amplitudes. The mode was used to estimate the phases, as the wrapping on
the unit circle hides the wings of the distribution and even the median will generally result in biased estimates. We can therefore refer to this statistical estimate taken from the evolutive impedance distribution as a ‘stationary impedance’ estimate.

另一种方法确定网站的阻抗是计算阻抗估计为每一次频率的元素。这给出了一个估计的瞬时阻抗的任何光谱的频率在任何时间。总阻抗地图,因此可以称为'演化阻抗' ,正如一位TFD的频谱是被称为一演化谱。由于阻抗是一个网站的功能和预计将不断为录音时间,瞬时阻抗估计,在任何光谱频率可以统计减少到一个单一的阻抗估计相等于说,所产生的平稳分析静止吨的数据集。由于其鲁棒性的非正常分布和离群,中位数是用来估计阻抗振幅。该模式是用来估计阶段,由于包装上
单位圆内隐藏的翅膀分布,甚至位数通常会导致偏见的估计。因此,我们可以参考这个统计估计,采取从演化阻抗分布作为一个'静止阻抗估计。
