16、 of glass, law (PV=nRT), through determination due to samples samples warehouse into samples by caused of samples samples warehouse gas capacity of reduced to precise determination samples of skeleton volume (containing closed hole), thereby get its really density, really density = quality/skeleton
17、volume.Gas expansion and substitution method is replaced by a gas discharge in the liquid sample volume.This method excludes the possibility of leaching method for sample dissolution, has the advantage of without damage to the sample.Because the gas can into the small samples of irregular air porosi
18、ty and surface subsidence, so sample size closer to the skeleton of the sample volume is measured, which can be used to calculate the density of the sample, the test values are closer to the true density of the sample.Instrument test system and standard of the sample the sample Bin bin form, as show
