5. (2) Either the amplitude modulation EMW or the ELF continuous and pulse EMW has the same results in producing the window bio effect.The modulation waves have the same frequency with the ELF waves;

• 生物学窗效应既可由ELF(极低频)正弦(调制波)振幅调制的高频电磁波(载波)产生,又可由ELF连续波或ELF脉冲波产生,只是前者的频率窗只体现在调制波频率上而不体现在载波频率上,而且,前者的窗效应频率与后者的窗效应频率是相同的;
