Study on Data Processing of Pod's Non-Destructive Measuring

The basic principle of the pod's non-destructive measuring based on vibration is that silkworm chrysalides' weight can be indirectly obtained by measuring the vibration energy eigenvalue of silkworm chrysalides. In the process of measuring, measuring resuits differ from each other. It s difficult to deter mine vibration parameter with the norm simple data processing. Provided with certain precision the neces sary measuring times can be determined through analyzing the vibration character of silkworm chrysalides and verifying the data distribution of silkworm chrysalides' vibration in terms of statistics.
