1. The method has solved the difficulty of the saltatory stress and the strain on the rotation symmetry face of cymbal transducer for bringing the design.

2. Particle degeneracy and its poor ability to tracking saltatory states are two main problems when a particle filter is applied to a fault prediction.

3. The third variation type is called saltatory variation type, which is formed from the liquid segregation mainly with immiscibility.

4. The extended particle filter can resolve the problem of particle degeneracy to a certain extent but can not track the saltatory state.

5. Conclusion The feature of mediastinal lymph node metastases in lung cancer may be saltatory and multiple.

6. While the diffusion effect is the process of pursuing scope economy when sports economy evolves to such an extent as to form periphery, saltatory and grading diffusion.

7. According to the operation principle of taximeter, this paper advances the mathematical model changing the continuous segmenting to saltatory segmenting, and probes into the application of this model.
