摘要：

The influence of the height of melt volume on temperature field in the melt is studied. The maximum velocity of ascending and descending flow has been determined for the Stockbarger growth using the ACRT for a crucible of 100 mm in diameter at Taylor number Ta > 10(8). The sharp increase in the amplitude of temperature fluctuations with decreasing height of the melt volume has been revealed. The increase in the amplitude of temperature fluctuations is caused by modulated crucible rotation. The ascending and descending flow velocity decreases on the axis of a cylindrical crucible with decreasing height of the melt volume. (C) 1999 Elsevier Science B.V. All rights reserved.
