1ppendi& The principle of 338 relief map ++; relief map is a new method to analy2e head bioelectricity in accordance with computer technology and computer picture disposal technology. As a new method around the world right now , it transforms huge comple9 but abnormity head bioelectricity to a form which could refle9 'uantitative change and orientation by computer. 7t displays comple9ion about diversification of head energy, it becomes an e9cellence , no wound and scientific method for s(ull sic(ness diagnose and research on head energy 'uantitative analysis. 7t is useful to analysis correctly on head energy using this technology .
