Theory and application study of on line test and self trigger ultrasonic passive localization for partial discharges(Ⅱ);

IInfluence of microphone phase difference on acoustic passive localization with two arrays;

The actuator adopts the principle of bionics and works with a new method of clamp passively and drive initiatively and a distortion structure with the thin shelf flexible hinge.

With the cross bearing technology and the principle of radio positioning as the basis,the design of the test route of passive positioning equipment under field test are given.

The emplacement is closely related with the regional and large ductile shearing; as a result of the difference of displacement component of shear zones, the favorable place for magmatic passive emplacement is provided, and formed the paleoplutonic rock of Dashan gneiss.
