Abstract
The physical meaning of the condition dμz/dt=0 in electron spin resonance(ESR)from a mathematical perspective is analyzed.The ESR theory has been extended from DC magnetic field to AC magnetic field,and the ESR theory under DC magnetic field is only a special case when the frequency of AC magnetic field is 0,thus establishing the ESR theory under general conditions and the method of implementing ESR under general conditions.The establishment of this theory can enable analytical instruments developed by means of the ESR principle to eliminate the high energy consumption,heavy weight,and high cost of DC magnetic fields.Only the original modulated magnetic field can be used to realize ESR,greatly reducing the volume,weight,energy consumption,and cost of the analytical instrument.It has a certain theoretical research and promotion application value.关键词
