脈動性水流装置 (Pulsating water pressure) の物理的性質 (第1報)

抄録

This study was carried out to evaluate the physical property of pulsating water pressure.
1. A water pressure in handpice of pulsating water pressure showed a correspondence with a magnitude of the force in the dial number.
2. A water pressure of handpiece at apical or the speed at which a water pressure rises were found almost in parallel in the magnitude of the force in the dial number.
3. If a spouting time was controlled, the water quantity of pulsating water pressure showed a marked decrease in a dial number 4 or 5 compared with 1 or 2.
4. A guantity of adhesive materials was removed by pulsating water pressure were found in parallel in the surface roughness on specimens.
