| 摘 要： | 文章从理论上探讨了用减压凝固法定量检测气体含量的条件和可能性，推导了计算公式；并使用减压凝固装置，通过控制试样的冷却速度和减压速度，使溶解在合金液中气体以气孔方式保留在试样中，测出试样密度，成功地计算出气体含量。

| Abstract: | Both theoretical and experimental investigation are carried Out to quantitatively determine gas solubility in liquid alloys with decompressing solidification device. It is found that turning the solved gas into gas phase and keeping it in sample by control.ling chilling condition and pressure-reducing velocity make it possible to measure the gas content by means of density detecting |
