Magnetostrictive materials belong to the intelligent material, when the external magnetic field changes, magnetostrictive materials can produce changes in the size or shape, Producing magnetostrictive phenomenon, for the displacement or force output.
We usually control the excitation voltage is used to realize the drive control of giant magnetostrictive materials.
If the magnetic fields are in the opposite direction, the magnetostrictive materials will shorten.
Because of the bias magnetic field, frequency doubling of magnetostrictive materials is disappear.

Due to multiple episodes of gold mineralization and multiple sources materials in ore-forming, there are heated debates on the era of the mine, and the main mineralization age of the Gupao gold deposit is focused on the Caledonian or Early Yanshanian.
The mineralization of it formed in several stages and its mineralizing materials originated from multiple sources [4, 5].
