求翻译：由此可见，当x在0.3~0.7之间时，复合材料在高频段出现了强化的自然共振峰，这可能是复合体系内BaFe12O19与BaTiO3之间的界面耦合相互作用所导致的。是什么意思？

Thus, when x in the range of 0.3 to 0.7, composite materials at high frequencies enhanced natural resonance peak, which may be caused by the interface coupling interaction between the composite system bafe12o19 and batio3.

It can be seen, when the 0.3 ~0.7 X between composite materials in high-frequency field, the strengthening of the natural resonance peak, this may be a composite system BaFe O 19 12 with 3 of the interface between BaTiO coupled interaction.

Thus it can be seen, when x when 0.3~0.7, the compound materials appeared the strengthened natural resonance peak in the high frequency band, this possibly is in the compound system between BaFe12O19 and the BaTiO3 contact surface coupling affects mutually causes.

We can see that when x is between 0.3~0.7, emerged in high frequency hardening of composite natural resonance peaks, this might be a compound system BaFe12O19 interface coupling caused by interaction with the BaTiO3.
