Result］ It could be concluded through analyzing the model that both the mass uncertainties of quinoline phosphomolybdate precipitates and tested samples were from the resolving power and precision of balance and its maximum tolerance in assay certificate; the uncertainty brought in by volumetric flask was from the permissible error of 250 ml volumetric flask, the operation of increasing the volume to scale of volumetric flask while diluting solution and the difference between experimental temperature and the temperature at the time when the volumetric flask was calibrated; the uncertainty brought in by pipette was from the permissible error of itself, the operation of increasing the volume to intake scale while taking solution and the difference between experimental temperature and the temperature at the time when the pipette was calibrated.

METHODS: Rat bilateral olfactory bulbs and olfactory mucosa at 1/3 nasal septum were obtained, sliced, digested in trypsin, and made into monoplast suspension. At 1×109/L, cells were incubated in uncoated 25 cm2 culture flask. At 18-20 hours, cell suspension was moved into another uncoated 25 cm2 culture flask (the first differential adhesion). At 24 hours, cell suspension was moved into a poly-D-lysine-coated 25 cm2 culture flask or poly-D-lysine-coated 6-well culture plate (the second differential adhesion). At 48 hours, parenchyma cells were removed after a half of medium was changed.

For the minimum dry density test of sand, test devices are improved to simplify the procedures and the test steps are adjusted to reduce the measurement error. The reverse graduated cylinder method and the tilting graduated cylinder method are recommended as the best methods for minimum dry density test and for leveling sand surface respectively. The optimum sampling quantity and the times of reversing graduated cylinder are studied.
