Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

On the basis of researches above, a prototype which consists of two paralleled DC/DC SEPIC converters with coupled inductors is designed. Some experiments have been made. The experimental results show that the approach proposed is accurate and feasible again.
