摘要

采用电接触技术对铝箔进行了冲击压缩下的电阻测量。冲击波压力p与电阻R和电阻率R的关系在压力范围高达22 GPa时得到。所发现的相关性R(p)是压力单调递增的平滑函数。r(p)的依赖关系更为复杂:随着压力的增加，电阻率先减小后增大。

Electrical Resistivity of Aluminum under Shock Compression

Electrical resistance measurements of aluminum foil are conducted under shock compression using the electric contact technique. Shock wave pressure p dependences of the electrical resistance R and the resistivity r are obtained for pressure range up to 22 GPa. The found dependence R(p) is a monotonically increasing smooth function of the pressure. The dependence r(p) is more complex: with increasing pressure, the electrical resistivity first decreases and then increases.
