中文摘要：研究了一种铝合金液氢含量快速检测方法。在该方法基础上设计了铝合金液氢含量快速测定装置。该装置通过动态改变测氢系统真空室的容积达到快速动态测定熔体氢分压的目的，具有结构简单、测试速度快、精度高和制造成本低的特点。设计了主要以石英砂、膨润土、水为主要材料，通过压制和烧结工艺实现成型的探头。实验证明，该方法可以满足实际测试中的各项指标。
英文摘要：A rapid method for measuring hydrogen content in molten aluminum alloy was studied. Based on the method, a device of rapid measuring hydrogen content in aluminum alloy liquid was designed. The device can fast measure hydrogen content in molten aluminum alloy through dynamic change of vacuum chamber volume in the hydrogen system. It has the characteristics of simple structure, rapid measuring, high precision and low manufacturing cost. The probe is designed and manufactured, which is formed through pressing and sintering quartz sand, clay and water. Experimental results show that this method can meet the actual needs of the various index.
