The importance of fixation in field in mycological study was discussed.

The application of polylactide in biomedical field was introduced, such as medicine slow release, bone screw fixation, surgical suture, ophthalmic material. And the prospects were outlooked.

Based on magnetic field and frictional-clamping principle, a new modularization design concept is presented for the fixation system of paper honeycomb parts with complex shapes.
