最近在我们实验室里建立了一套加磁场高温光学实时观察装置．作为磁场发生器的电磁铁，在发热体中心最高可产生0.14T的侧向磁场．运用这套加磁场实时观察装置，能有效地阻抑KNbO3熔体内的重力对流，减少界面边界层厚度．
A magnetic-field applied to high temperature optical in situ observation (M in situ observation) technique was established in
the authors’ laboratory. An electromagnet was used as a magnetic field generator. This magnet was designed to supply up to 0.14T transversely to the center
of the heater.
By using M in situ observation technique, the relative extent of boundary layer can be reduced and the buoyancy driven convection can also be damped.
The effect of the magnetic-field upon oxide crystal growth was verified tentatively.
