1 Pore The image of the pore can be presented on the negative as an isolated or group of round, oval, pear-shaped dark spots, smooth contours, sharp images, the whole image blackness is large, no obvious changes. 2 Sparseness Sparseness is small, discrete holes distributed throughout the thickness of the casting. The image presented on the negative is related to the thickness of the casting. Thin sections may show up as fine reticulated images; thick sections will show up as faint dark spots,...

Brief description of the molecular sieve problem The purifier CO₂ suddenly started to run abnormally and suddenly went out of range in liquid air separation plants, the dew point never changed significantly. The dew point did not change significantly. In order to ensure that the other molecular sieve had enough time to regenerate, the time could not be shortened any further. At this point there was a relatively stable situation with no further deterioration. Check the trend graph for a cold bl...
