[求助] 求助段落翻译(汉译英,信号处理相关)

能者,请帮忙!汉译英
段落:大地电磁信号非线性动态变化特征可被HHT方法较好地刻画出来:1)HHT方法对大地电磁信号的动态变化过程刻画得比较清楚,反应了大地电磁信号的非线性、非平稳性,每时段都有各自的频率特性、能量差异,其它方法难于揭示出这些细微性变化,这种变换特征为地下介质的研究提供一种新的思路与方法;2)时频谱阵图上的能量主要集中在0~1000Hz内,这与实际大地电磁低频模式的频率设置范围是10~1000 Hz情况相符;3)在IMF序列曲线上和时频谱值图像中, 大地电磁数据的突变点、持续时段和频带能量分布均能够清晰地显现,验证了HHT方法具有完全局部时频特性。

MT signal nonlinear dynamic characteristics can be portrayed well by HHT Method:
1) HHT Method describes the dynamic changing process of magnetotelluric signals clearly, reflects(中文应为“反映”)that the magnetotelluric signals is non-linear, non-stationary and every time interval has its own frequency characteristics, energy difference, therefore other methods have difficulty to reveal these minor changes. The characteristic changing provides a new thought and method for the research of underground media;
2) The time frequency spectrum matrix concentrated mainly in the range of 0-1000Hz, which accord with the actual land of low-frequency electromagnetic mode set of 10-1000 Hz;
3) In the IMF sequence curve and time frequency spectrum, the mutation point of magnetotelluric data, and sustained periods and energy distribution are able to clearly show, which certificated that the HHT method has full local time-frequency characteristics.
