4.Investigation Development of the Explosion-Suppression Characters of multiplayer Mesh-hole Construction
5.When designing the stencil aperture itself, common practice is to work backwards from the bump specification.
6.Methods The natural porous hydroxylapatite (NPHA) and bone morphogenesis protein (BMP) were combined as NPHA/BMP complex.
7.This technique is the biotechnology equivalent of screening sand through progressively finer meshes to determine particle sizes.
8.For a given aperture size and vibration acceleration, the relations between material flow, flow time and vibration frequency were studied by experiments.
9.Plymesh aeration pads are used to fluidize and to optimize the flow rate of powdered and pulverized products in silos and in bunkers.
10.Methods HA/TCP ceramics were sintered at 1250℃and fabricated into tube like columns of Φ18 mm×30mm with a central hole of Φ4mm. Bone like apatite was precipitated on the ceramics by immersing the ceramics in dynamic revised simulated body fluid (RSBF) before implantation. 13 male dogs were used in this study, and a 30mm long segmental bone defect was made in the middle of one femur of each dog.
