B, voltage-withstand test is carried out in the boric acid test fluid of 70g/L, pressure stabilizing 3 minutes；
C, after the sample after voltage-withstand test being cleaned with ultrapure water, 100 DEG C oven 3 minutes；
D, sample to be tested is taken out, after placing room temperature, is integrally applied at the sample to be tested back side and is covered with one or two layers with solidification filling
The substance of sealing function, and keep to drying regime；
E, sample is put into the ammonium pentaborate test fluid of 80g/L and carries out volume test, gained capacity is sample to be tested single side appearance
Amount.
A further improvement of the present invention is that: the substance with solidification filling sealing function in step D is acrylic acid tree
Rouge, alkyd resin, epoxy resin, liquid glue, adhesive tape or transparent nail polish.
Compared with the prior art, the present invention has the following advantages:
Because the microstructures such as positive and negative corrosion layer aperture, hole density are different, show and be presented as on macro property than having
Institute's difference, traditional specific volume test method fail to show specific specific volume front and back.The present invention can be very good characterization electrode
