1. The dredging machine comprises a main vehicle with a vehicle body leg device and a tilter, and a deep well dredging device and an abutment device which are arranged on the frame of the main vehicle.

2. Some technical questions were analysed and discussed in this article. These questions are about the cleaning, tilter sterilization, bacteria-free packing, etc.

3. Compared with the one stage low-pass filter, the designed three stage decimation filter has much less computation and better tilter character.

4. Spreaded spores and mycelium of Aspergillus fumigatus onto slides and used immunofluorescent assay to identify antibody tilter of mice serum.

5. Coatd plate bar using recombinant GM protein (AFMP1) and employed indirect ELISA to detect antibody tilter of mice serum.

6. Check the inner and outer sides of the foam insert and the filter paper inside the tilter.
