Covering power, throwing power, polarization value, polarizability, peak point potential and peak point current of the brightener are also almost equal to those of the abroad counterparts.
The measuring vibrating signal method may be used on real time, mean while, vibrating signal can be measured by peaktopeakvalue or true virtual value .
