The quality of device 112, m02For the quality of porcelain crucible 113, m11For the first sample and the common mass of reticular structure container 112, m12For
The common mass of second sample and porcelain crucible 113, m21For 1 unit interval (such as third sample and reticular structure in one hour
The common mass of container 112, m22For the common mass of the 4th sample and porcelain crucible 113 in 1 unit interval.
Under normal circumstances, multiple unstable rock sample mass percents can be obtained to carry out the stability analysis of rock sample, this is just
Each predetermined time is needed once to be tested.For the experimentation of first time with reference to the above, second of later experiment will
Without measuring quality m again01, quality m02, quality m11And quality m12.What above-mentioned quality was all no variation in.It only needs to obtain
Quality mj1With quality mj2.Their acquisition modes concrete operations are as follows：
The porcelain crucible 113 of the above-mentioned reticular structure container 112 with third sample and the 4th sample of band is put back into fluid cylinder 111,
Continue timing, again may be by the η that above-mentioned calculation formula is calculated in other timesiValue, and then according to above-mentioned multiple ηi
Obtain ηiRelation curve is changed over time, and then evaluates stability of the rock sample in the liquid to be evaluated.
It should be noted that：In experiment, it is ensured that liquid to be evaluated is constant, replaces a variety of rocks, then can evaluate
Stability of the different rocks in same liquid.Similarly, using same rock, different liquid to be evaluated is replaced, then can be evaluated
Influence of the different liquids to the rock stability.
