摘要: 本文简单介绍了双金属结冲击压力传感器的性质、特点、结构和应用范围。给出了三种形式的铜-康铜传感器的结构参数和一定实验条件下的V-p响应关系。在实验的压力范围内基本上为一直线，并给定了这些直线的拟合方程。实验结果的分散性，在45 GPa时小于12%，而在80 GPa和116 GPa时小于8%。结合具体实验，用Ⅲ型传感器探测了Al-Cu飞片击靶时产生的双波压力及时间间隔，同理论预估结果符合较好。Abstract: This paper briefly describes the behaviors, feature, construction and application of the bimetallic junction sensor. It also presents the construction parameters for three combined types of sensors and their V-p curves under the experimental conditions, which show that there principally exists a linear dependence in the pressure range. Their fitting formulae are also given. The diversity of the experimental results are less than 12% at the pressure of 45 GPa and less than 8% at 80 GPa and 116 GPa, respectively. The pressures induced by the double shock waves and their time interval were measured by type Ⅲ sensor. The obtained results are in good agreement with the predicted values.
