查询词典 conductivity

The ionic space charge in the micro-voids of water tree will produce a period vibration by AC voltage stimulating. Under superposition voltage, the vibration can impel the ion penetrating into the tiny crackle between micro-voids of water tree and lead to a change in the conductivity of water tree. With this the ultra-low frequency spatial current signal of the water tree would be emerged in detecting circuit. The polarization and depolarization of the polar end-group of the PE formed in water tree developing will also contribute to this special signal.
