Soil classification References: 1. Holtz, Robert, D., Kovacs, Williams, D. An Introduction to Geotechnical Engineering. Englewoods Cliffs, New Jersey; Prentice-Hall, 1981. ... • Sand fraction = percent passing through the number 200 sieve = F 200 • The Course grained soils are then divided into Gravel (R 4 > 50) and Sand (R<= 50)

The slot width, or the screen gauge, is sometimes sized to be equal to the formation sand grain size at the 10-percentile point of the sieve analysis. The theory is that because the larger 10% of the sand grains will be stopped by the openings of the screen, the larger sand will stop the remaining 90% of the formation.

In the real mobile screen production line, the yield of normal products is relatively high, so some defects are difficult to collect. Besides, samples of emerging defects are difficult to collect in large numbers in a short time. To address the few-shot problem caused by these, we propose a few-shot classification method to simultaneously recognize both the …
