中文摘要	A non-destructive evaluation (NDE) system was set up in our laboratory. A high-T-c dc superconducting quantum interference device (dc SQUID) made from YBa2Cu3O7-delta thin film on a 24degrees bicrystal SrTiO3 substrate was adopted as the magnetic flux sensor. Novel excitation coils and a balance circuitry were proposed and employed for evaluation of multilayer aluminium structure with artificial slits in an unshielded noisy environment. Our experimental data demonstrate that the NDE system with proper location of two thin excitation coils could make full use of the dynamic range of the SQUID and enhance the spatial resolution of detection.
