1. alleviate the method for the tin one of the main divisions of the male role in traditional opera length on substrate surface, it comprises the following steps:

  • The first solution is prepared to water by adding a certain amount of water-soluble gold-containing compound;

    Add the first complexing agent to described first solution;

    Add the second complexing agent to described first solution;

    Prepare the second solution, it comprises a certain amount of buffer reagent be dissolved in water;

    Add water-soluble sn-containing compound to described second solution;

    In conjunction with described first and second solution to form the 3rd solution, it comprises a large amount of gold in solution and tin ion;

    Anode electrode is immersed described 3rd solution,Cathode substrate is immersed described 3rd solution, described cathode substrate comprises cathode substrate surface;

    Described anode electrode and described cathode substrate are connected to the power supply that can provide electric current;

    Open described power supply to provide described electric current to described anode electrode, described cathode substrate and described 3rd solution;

    WithBy a certain amount of gold and tin codeposition to described cathode substrate on the surface.
