thickness loss
2.If weight bearing or stress loading of the affected joint continues， thinning of the cartilage may progress to eventual full-thickness cartilage loss.
3.The thickness of the films could be effectively controlled by changing the electrophoretic time. When the thickness of the films reaches 30μm,the best general performance have been got: dielectric constant ε33T/ε0=781,dielectric loss tanδ=0.0083,remnant polarization Pr=24.6μC/cm2 and coercive field Ec=61.9kV/cm.
7.The best approach to an estimate of heat loss by this mechanism may be to calculate the heat loss by conduction and to adjust the effective wall thickness used in the conduction calculation to take in to account the fact that air motion will strip away the heated layer surrounding the skin and increase the transfer of heat to the air.
8.The disperse uniformity of EPS in cement was improved by special surface treatment technology of EPS. The microwave loss mechanism of this absorbing material was analyzed and the influences of EPS filling patio, EPS bead diameter and sample thickness to absorbing property were analyzed by energy conservation principle.
9.The horizontal and vertical momentum loss caused by the shock of heavy rain in low-level wind shear of thunderstorms on the airframe and wing are analyzed, the water film thickness on the airframe and wings estimated, and the flight resistance resulted from raindrops-striking caused by the roughness of airplane when the heavy rain shocks the airplane is discussed.
10.In this paper,high heat penetration into a moving particulate bed is described mathematically with a comprehensive heat and mass transfer model.The distribution of gas velocity and pressure,the temperature field of gas and solid in the moving particulate bed are examined for different conditions.The results show that thermal penetration into the moving packed-bed particles by fluid flow in porous media is high only in the position near the gas entrance.The thermal penetration thickness tends to increase with the fluid flow velocity and decrease with the particle moving velocity.In the region of thermal penetration,the porosity of solid bed has significant effect on gas field and pressure loss.it is feasible to reduce the gas pressure loss by a larger width/height packed bed in design and operation.The correspondence between thermal infection depth and particle bed height would be helpful to keep high oapacity of reactor and reduce the cost of operation.
