- A spherical cavitated bifurcation problem is examined for a solid sphere composed of a class of compressible hyper-elastic materials.
- After a thermodynamics calculation,it was found that it is possible for the die to be cavitated in normal work condition.
- It is suggested to weld and apply anti-abrasion-cavitation material on seriously cavitated area, obvious result has been abtained.
- IRM cement, Cavit, Dycal, but also Grossman cement lowers the bonding strength of a composite material to dentin by one-half of the control value.
- Conclusions Today Ivalon painless hemostasia sponge are idea nasal cavit filling material. Furthermore it brings forward new demand to clinical nursing.
- The high efficiency and high cleaning degree of ultrasonic washing is benefit from penetrability and cavit action shock wave while its sound wave is spreading into the medium.
