Step 1 measures the porosity of sample 3.The measurement of porosity is to be based on Archimedes principle, uses water-boiling method in test
Measure the porosity of electrode.Firstly, weighing the sample dry weight needed, it is denoted as m0；Ground sample will have been weighed and be put into clean beaker
In, distilled water is injected into cup, until flooding sample；Then it places the beaker and is heated to boiling in thermostatic drying chamber, and keep
Fluidized state 2h infiltrates into distilled water completely in the hole in TiO2 electrode；Then stop heating down to room temperature.Then
Sample is quickly removed to be put into and gets out the small of weighing in advance and hangs in basket, is hung on the suspension hook of balance, continues sample
It is immersed in water, weighs the suspension weight of saturated sample in water, be denoted as m1；Saturated sample is taken out, is carefully wiped with wet rag
The water of desaturation specimen surface quickly weighs the quality of saturated sample, is denoted as m2；The porosity of electrode: P=is calculated by formula
(m2-m0)/(m2-m1)。
Step 2, in 3 central bore of sample, 301 depth of drilling are 2/3 rock sample height to be measured, and 301 diameters of drilling are
