An abnormal condition variously characterized by stupor, stereotypy, mania, and either rigidity or extreme flexibility of the limbs.It is most often associated with schizophrenia.
Symptoms such as nausea,vomiting,dizziness and dystaxia were common in this group of patients,and headache and nuchal rigidity were found in 51.6% and 32.3% patients respectively.
The cutters used in high speed machining(HSM) have poor rigidity, therefore the method fits to HSM of die cavity due to the unfluctuating cutting force characteristic.
That we use finite element analysis calculate to the strength and the rigidity of the bodywork structure.Thus the optimum fillet of the small underframe structure can be specified.
In this paper , a rigidity theorem of hypersurface in real space form will begiven.In addition, we obtain rigidity theorems of submanifold in sphere which improvethe result of Hou and Xu.
