3.The stability of the Ekman flow during ACRT (accelerated crucible rotation technique) process, and the effects of the crucible diameter Φ, the maximum variation of the rotation speed, △ωmax , as well as the liquid height H in the crucible on the Ekman flow,were studied with hydraulic analogue experiments.

4.In the process of single crystal growth,the carbon is incorporated into silicon lattice through the way which molten silicon absorbs CO gas. This CO gas is generated from interaction between silica crucible and graphite crucible.

5.Test A: porcelain Crucible ? A porcelain crucible was heated to a dull red color, placed on the test material, and allowed to cool to ambient temperature.
测试A：陶瓷坩埚。将置于所测试材料表面的陶瓷坩埚，加热至暗红色然后让其冷却，温度降至室温。
6.The result shows that, if Reynolds number Re ≤ ReC1(the low critical Re), the Ekman flow is stable, if Re≥ ReC2(the high critical Re), the Ekman flow during the crucible deceleration period is unstable, and the Ekman flow height h increases with increase of the crucible diameter Φ and the maximum variation of the rotation speed △ωmax .
结果表明，当雷诺数Re＝0．678R（｜△ωmax｜／v）0．5≤ReCl（下临界值）时，Ekman流场稳定； Re≥ReC2（上临界值）时，减速过程的Ekman流场完全不稳定。
7.CRUCIBLE 416R should be forged at 2050 to 2150°F (1121 to 1177°C) and finished above 1400°F (760°C). CRUCIBLE 416R is not adaptable to severe upset forging operations.
在小弟我以前做事的铸造工厂,只要是碰到3字头与4字头铸件变形,都需要热处理后才能整形.要不然内部会产生应力导致铸件破裂.
