2.DENSITY GRADIENT EFFECTS IN THE TOKAMAK EDGE TURBULENCE WITH TEMPERATURE GRADIENT DRIVING
8.Comparing with the ultrasonic transmission method, the reflection|transmission method averts the influence of temperature gradient and pressure gradient in the chamber of sample.
9.Finite element method was used for the calculation of temperature field, temperature gradient and thermal stress of the coal water slurry (CWS) ceramic nozzle.
10.The high optical quality Yb∶YAG boules,76mm in diameter, were grown by temperature gradient technique (TGT).
