Fundamentals of contrast matching in porous media with pressurised gases

We propose to perform systematic SANS and USANS measurements of contrast matching of porous media with pressurised gases to establish standard procedures for this technique. We...我们拟针对多孔介质与加压气体的对比匹配（contrast matching）开展系统性小角中子散射（Small Angle Neutron Scattering, SANS）与超小角中子散射（Ultra-Small Angle Neutron Scattering, USANS）测量，以确立该技术的标准操作流程。我们……
